Full textAbstract:
Distributed Denial of Service attacks are an ever prevalent challenge for system administra-tors today to overcome. The attack, which is all about restricting legitimate users access to a service, such as a web-page. Can cost companies and governments millions of dollars if not properly managed. This study aims to explore if there is any difference in performance between some of the most modern iterations of popular server operating systems today. Those server operating systems are: Windows Server 2016, Ubuntu 16 and FreeBSD 11. And submitting them to one of the most popular DDoS attacks at the time of writing, a so called HTTP-Get request. The webservers used are some of the most widely used today, Apache and Microsoft IIS. Each server will be submitted to attacks, and compared between one another. Different de-fence methods will also be tested and examined. Tests include shorter tests that is repeated multiple times for data validity, and one longer test for every condition in order to control if the results are similar. During these tests, the operating systems will measure CPU/RAM utilization, and a control computer will measure Round Trip Time. Windows Server 2016 using IIS and FreeBSD 11 perform similarly resource wise, but Win-dows Server 2016 with IIS had a better Round Trip Time performance. Windows Server 2016 with Apache performs worst in all measurements, while Ubuntu 16 performs in the middle, but has the most stable performance.

Full textAbstract:
International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, CaliforniaThis paper illustrates a device driver implementation used to support a PC compatible telemetry device. Device requirements included operation on Windows NT 4.0, Windows 95, Windows NT 5.0 and Windows 98 platforms. A single device driver was not possible due to the differences between driver requirements on the various operating systems. The Windows Driver Model (WDM) was considered for NT 5.0 and Win98, however, NT 4.0 and Win95 does not support the WDM. To minimize software development and support efforts, it was clear that an architecture compatible to both WDM, NT 4.0 and Windows 95 needed to be developed. The resulting layered device driver architecture provides a common upper interface and uses a register based model to describe the hardware at the lower interface. The common upper interface is compatible with all of the target operating systems and presents a consistent Applications Programming Interface (API) for the telemetry application developer. The lower interface is specific for each platform but contains minimal device specific functionality. A simple register I/O driver is easily implemented using all of the target operating systems. The layered architecture and register based interface to the hardware results in a multiple operating system code set which differs only at the lowest layer.

The purpose of this thesis is to investigate if there are environments that use some kind of central authentication system within institutions/schools. The hypothesis is that an institution not using a form of central authentication service has more need for maintenance and as such is considered a higher cost for the organization. The gathering of data has been done through interviews with technical personal at Blekinge Tekniska Högskola and Linköpings Universitet. Based on the technical background of the authors, and the system limited to discussing Windows and UNIX operating systems, a discussion and analysis of the systems working today has been done, with emphasize on the hypothesis.

Migration from an existing information technology system to a new system presents many managerial challenges. There are technological challenges associated with running the old system, maintaining data integrity and bringing the new system online all without seriously impacting daily operations. There are human factors to consider like resistance to change and conflict management. In addition, organizational issues like management support and cross functional communication channels need to he addressed. This thesis reviews the technical migration from an operational NetWare network to Windows NT completed at the Defense Manpower Data Center (DMDC) in Monterey, CA. The DMDC case presents a typical set of issues that an IT manager is likely to face when implementing technology driven change. Technical, human and organizational factors of technical change are discussed. A list of lessons learned and a set of technical management guidelines are derived from analysis of the DMDC case. Details of Windows NT 4.0 and 5.0 features are included.

This thesis investigates how different Linux-distributions installation interface relate to the ISO 9241 standard, parts 12 and 13, and how they relate to the installation interface of Windows XP, with the hypothesis: "There is a Linux-distribution whose installation interface according to applicable HCIrecommendations is equivalent to that of Windows XP." With the checklists provided by ISO 9241 an empirical study has been made, and so comparable measurements of how well the Linux-distributions and Windows XP follows the recommendations of the standard was obtained. By comparing the results from the tests similarities and differences between the installation interfaces can be deducted. As the result and the conclusion shows there are Linux-distributions whose installation interface, according to the applicable HCI-recommendations, are equivalent to that of Windows XP.

Full textAbstract:
The importance of effective and efficient distribution is evident from its associated costs. Transportation and shipping alone comprise roughly 15 percent of a product's sales in the U.S. Physical distribution is very energy and labor intensive, which have both become relatively more expensive in the last 10-15 years. Not surprisingly, there is a growing demand for automated planning systems that produce economical routes. Other than the cost savings, introduction of these systems enables companies to maintain a higher level of service for their customers, it makes them less dependent on human planners, it supplies better management information facilities and it makes distribution planning work faster and simpler.

Amazon.com is a leading retailer and UPS is the leading package delivery company in the world. Amazon spends hundreds of millions of dollars each year shipping products to customers via parcel carriers such as UPS. Arguably, both companies rely on each other for their future success and are therefore interested in developing a closer relationship. But supplier collaboration efforts are challenging and partnerships between industry leading companies are not common. This research paper demonstrates a case study where two industry giants are working together on a process improvement projects to better serve their customers. This project has a goal of finding opportunities to delivery and sort UPS Ground packages more efficiently so as to allow for a longer window of time each day that the UPS Ground ship method is available. Additional goals exist around implementing more consistent processes and delivering product to UPS earlier in the evening for more efficient sorting. This project demonstrated that significant transportation savings can be achieved through these process improvements. Amazon and UPS are able to work together in a productive way to strengthen their long term relationships.

Full textAbstract:
The purpose of this study has been to evaluate the usability of Windows 8 when using keyboard and mouse. Sub goals have been to uncover the usability problems and to generate recommendations for organizations upgrading to Windows 8.Usability testing according to ISO/IEC 25062:2006 was performed on users that had experience from Windows 7. Tests were performed on both Windows 7 and 8 for comparison purposes. Interviews with administrators involved in the operating system migration process were conducted. The interviews were performed to identify problems with previous migration processes.This study uncovered usability problems in Windows 8. Usability tests performed gave negative results in categories of effectiveness, efficiency and satisfaction for Windows 8. The severity of the usability problems uncovered was high and affected the usability of the system. Problems were caused by fundamental Human Computer Interaction mistakes made by the design and from introducing a new mental model for navigation. Hidden functions proved to be one of the large problems for users when trying to execute their daily tasks.The interviews of the administrators uncovered experiences made from earlier migration processes. The lack of training provided to the employees and the introduction of new IT solutions in an organization resulted in a lower satisfaction score on the yearly employee report. Comparing results from the usability testing with feedback from the interviews have been used to suggest topics for training. The topics for training cover the elements and functions that users struggled with during the usability testing of Windows 8. Other measures for an easier transition when upgrading to a new operating system have been proposed.

Die Arbeit präsentiert ein Multimedia-Framework für Linux, das im Unterschied zu früheren Arbeiten auf den Ideen "retained-mode processing" und "lazy evaluation" basiert: Statt Transformationen unmittelbar auszuführen, wird eine abstrakte Repräsentation aller Medienelemente aufgebaut. "renderer"-Treiber fungieren als Übersetzer, die diese Darstellung zur Laufzeit in konkrete Operationen umsetzen, wobei das Datenmodell zahlreiche Optimierungen zur Reduktion der Anzahl der Schritte oder der Minimierung von Kommunikation erlaubt. Dies erlaubt ein stark vereinfachtes Programmiermodell bei gleichzeitiger Effizienzsteigerung. "renderer"-Treiber können zur Ausführung von Transformationen den lokalen Prozessor verwenden, oder können die Operationen delegieren. In der Arbeit wird eine Erweiterung des X Window Systems um Mechanismen zur Medienverarbeitung vorgestellt, sowie ein "renderer"-Treiber, der diese zur Delegation der Verarbeitung nutzt.

Behzadnia, Peyman. "Dynamic Energy-Aware Database Storage and Operations." Scholar Commons, 2018. http://scholarcommons.usf.edu/etd/7125.
Full textAbstract:
Energy consumption has become a first-class optimization goal in design and implementation of data-intensive computing systems. This is particularly true in the design of database management systems (DBMS), which is one of the most important servers in software stack of modern data centers. Data storage system is one of the essential components of database and has been under many research efforts aiming at reducing its energy consumption. In previous work, dynamic power management (DPM) techniques that make real-time decisions to transition the disks to low-power modes are normally used to save energy in storage systems. In this research, we tackle the limitations of DPM proposals in previous contributions and design a dynamic energy-aware disk storage system in database servers. We introduce a DPM optimization model integrated with model predictive control (MPC) strategy to minimize power consumption of the disk-based storage system while satisfying given performance requirements. It dynamically determines the state of disks and plans for inter-disk data fragment migration to achieve desirable balance between power consumption and query response time. Furthermore, via analyzing our optimization model to identify structural properties of optimal solutions, a fast-solution heuristic DPM algorithm is proposed that can be integrated in large-scale disk storage systems, where finding the most optimal solution might be long, to achieve near-optimal power saving solution within short periods of computational time. The proposed ideas are evaluated through running simulations using extensive set of synthetic workloads. The results show that our solution achieves up to 1.65 times more energy saving while providing up to 1.67 times shorter response time compared to the best existing algorithm in literature.
Stream join is a dynamic and expensive database operation that performs join operation in real-time fashion on continuous data streams. Stream joins, also known as window joins, impose high computational time and potentially higher energy consumption compared to other database operations, and thus we also tackle energy-efficiency of stream join processing in this research. Given that there is a strong linear correlation between energy-efficiency and performance of in-memory parallel join algorithms in database servers, we study parallelization of stream join algorithms on multicore processors to achieve energy efficiency and high performance. Equi-join is the most frequent type of join in query workloads and symmetric hash join (SHJ) algorithm is the most effective algorithm to evaluate equi-joins in data streams. To best of our knowledge, we are the first to propose a shared-memory parallel symmetric hash join algorithm on multi-core CPUs. Furthermore, we introduce a novel parallel hash-based stream join algorithm called chunk-based pairing hash join that aims at elevating data throughput and scalability. We also tackle parallel processing of multi-way stream joins where there are more than two input data streams involved in the join operation. To best of our knowledge, we are also the first to propose an in-memory parallel multi-way hash-based stream join on multicore processors. Experimental evaluation on our proposed parallel algorithms demonstrates high throughput, significant scalability, and low latency while reducing the energy consumption. Our parallel symmetric hash join and chunk-based pairing hash join achieve up to 11 times and 12.5 times more throughput, respectively, compared to that of state-of-the-art parallel stream join algorithm. Also, these two algorithms provide up to around 22 times and 24.5 times more throughput, respectively, compared to that of non-parallel (sequential) stream join computation where there is one processing thread.

Full textAbstract:
Since the Asian Financial Crisis of 1997 and the Global Financial Crisis of 2007, members of the Association of Southeast Asia Nations (ASEAN) have sought to strengthen ASEAN’s regional economies through a digital trade project known as the ASEAN Single Window (ASW). The purpose of this case study was to explore the business strategies that multinational organizational leaders used to overcome business barriers while implementing ASEAN partnership contracts and ASW region-wide projects. This study may be unique in that, at the time of this research, there was no published study in which researchers had explored a single window for a vast, multination geographical region. Data collection was done via in-depth interviews with ASW executives, studying online ASW-related conferences, and examining relevant strategic documents. A 6-phase thematic analysis process based on methodological triangulation corroborated the data and addressed construct validity through data familiarization, generating initial coding, categorizing codes and searching for themes, breaking codes into subcategories, data reduction and defining and naming themes, and report generation. The 4 strategic themes that emerged were business models and processes, public–private partnerships, project management methodologies, and overlapping themes. The findings offer insights into ways to overcome the ASW’s constraints and barriers. These strategic themes developed into a list of critical success factors and a summary list of principle business strategies and best practices. The implication for social change is a regionally collaborative trading environment providing potential economic options that not only impede the deterioration of the regional social fabric but support new opportunities such as trade liberalization and economic stability.

Classically, wide-area synchronized power system monitoring has been an expensive task requiring significant investment in utility communications infrastructures for the service of relatively few costly sensors. The purpose of this research is to demonstrate the viability of power system monitoring from very low voltage levels (120 V). Challenging the accepted norms in power system monitoring, the document will present the use of inexpensive GPS time synchronized sensors in mass numbers at the distribution level. In the past, such low level monitoring has been overlooked due to a perceived imbalance between the required investment and the usefulness of the resulting deluge of information. However, distribution level monitoring offers several advantages over bulk transmission system monitoring. First, practically everyone with access to electricity also has a measurement port into the electric power system. Second, internet access and GPS availability have become pedestrian commodities providing a communications and synchronization infrastructure for the transmission of low-voltage measurements. Third, these ubiquitous measurement points exist in an interconnected fashion irrespective of utility boundaries. This work offers insight into which parameters are meaningful to monitor at the distribution level and provides applications that add unprecedented value to the data extracted from this level. System models comprising the entire Eastern Interconnection are exploited in conjunction with a bounty of distribution level measurement data for the development of wide-area disturbance detection, classification, analysis, and location routines.
The main contributions of this work are fivefold: the introduction of a novel power system disturbance detection algorithm; the development of a power system oscillation damping analysis methodology; the development of several parametric and non-parametric power system disturbance location methods, new methods of power system phenomena visualization, and the proposal and mapping of an online power system event reporting scheme.Ph.

Full textAbstract:
Autonomy in multi-robot systems is bounded by coordination among its agents. Coordination implies simultaneous task decomposition, task allocation, team formation, task scheduling and routing; collectively termed as task planning. In many real-world applications of multi-robot systems such as commercial cleaning, delivery systems, warehousing and inventory management: spatial & temporal constraints, variable execution time, and energy limitations need to be integrated into the planning module. Spatial constraints comprise of the location of the tasks, their reachability, and the structure of the environment; temporal constraints express task completion deadlines. There has been significant research in multi-robot task allocation involving spatio-temporal constraints. However, limited attention has been paid to combine them with team formation and non- instantaneous task execution time. We achieve team formation by including quota constraints which ensure to schedule the number of robots required to perform the task. We introduce and integrate task activation (time) windows with the team effort of multiple robots in performing tasks for a given duration. Additionally, while visiting tasks in space, energy budget affects the robots operation time. We map energy depletion as a function of time to ensure long-term operation by periodically visiting recharging stations. Research on task planning approaches which combines all these conditions is still lacking. In this thesis, we propose two variants of Team Orienteering Problem with task activation windows and limited energy budget to formulate the simultaneous task allocation and scheduling as an optimization problem. A complete mixed integer linear programming (MILP) formulation for both variants is presented in this work, implemented using Gurobi Optimizer and analyzed for scalability. This work compares the different objectives of the formulation like maximizing the number of tasks visited, minimizing the total distance travelled, and/or maximizing the reward, to suit various applications. Finally, analysis of optimal solutions discover trends in task selection based on the travel cost, task completion rewards, robot's energy level, and the time left to task inactivation.

Full textAbstract:
Physiological signals, which are controlled by the autonomic nervous system (ANS), could be used to detect the affective state of computer users and therefore find applications in medicine and engineering. The Pupil Diameter (PD) seems to provide a strong indication of the affective state, as found by previous research, but it has not been investigated fully yet.
In this study, new approaches based on monitoring and processing the PD signal for off-line and on-line affective assessment (“relaxation” vs. “stress”) are proposed. Wavelet denoising and Kalman filtering methods are first used to remove abrupt changes in the raw Pupil Diameter (PD) signal. Then three features (PDmean, PDmax and PDWalsh) are extracted from the preprocessed PD signal for the affective state classification. In order to select more relevant and reliable physiological data for further analysis, two types of data selection methods are applied, which are based on the paired t-test and subject self-evaluation, respectively. In addition, five different kinds of the classifiers are implemented on the selected data, which achieve average accuracies up to 86.43% and 87.20%, respectively. Finally, the receiver operating characteristic (ROC) curve is utilized to investigate the discriminating potential of each individual feature by evaluation of the area under the ROC curve, which reaches values above 0.90.
For the on-line affective assessment, a hard threshold is implemented first in order to remove the eye blinks from the PD signal and then a moving average window is utilized to obtain the representative value PDr for every one-second time interval of PD. There are three main steps for the on-line affective assessment algorithm, which are preparation, feature-based decision voting and affective determination. The final results show that the accuracies are 72.30% and 73.55% for the data subsets, which were respectively chosen using two types of data selection methods (paired t-test and subject self-evaluation).
In order to further analyze the efficiency of affective recognition through the PD signal, the Galvanic Skin Response (GSR) was also monitored and processed. The highest affective assessment classification rate obtained from GSR processing is only 63.57% (based on the off-line processing algorithm). The overall results confirm that the PD signal should be considered as one of the most powerful physiological signals to involve in future automated real-time affective recognition systems, especially for detecting the “relaxation” vs. “stress” states.

Different embedded OSs tackle these constraints in different ways. We survey two of the more popular embedded OSs: Linux and Windows CE. To reveal their strengths and weaknesses, we examine and compare each of the OS’s process management and scheduler, interrupt handling, memory management, synchronization mechanisms and interprocess communication, and power management.text

Security damage about “Unauthorized use” are usually be discovered after it happened. And it costs about 50% financial loss in 30% respondents in 2006, CSI/FBI. Because of the popularity of Microsoft Window operation system, we discuss the “anomaly user behavior” in recent papers. After that we propose a view about “too large”, “include too many system information” in dataset that used for building normal user behavior model. It brings information security analyzer a lot of inconvenient in Microsoft Window OS environment.Then, we reference the thought, “Window Title”, and recommend a kind of dataset. The proposed dataset takes advantage of “few dataset”, “distinguish anomaly user behavior”.Finally, we use “Support Vector Machine” to verify the effect, and give some experimental results to explain the cuts of the dataset in our proposed system.

The driver is an interface of the communication of computer and peripheral device, so the connection between most devices and operating systems needs assistance via it. In Microsoft's window operating system, the driver is a very complicated set of Kernel-Mode Code. After the driver loads to the operating system, set about disposing the hardware interface in the operating system at once, and manage the system demand during operation, so the relation between the driver and operating system is close. That is to say, the developer of the driver does not have relevant background knowledge, and then the development of the program may encounter the difficulty. In this thesis, we combine the development concept of the software and hardware, and set up the development environment of USB device driver, so the user can utilize this environment to produce the driver fast. Passing the package simulation device that we designed, it can imitate USB device and convey the package. Our design method can get the result of planning and proving each other of the software and hardware, and even there is not any hardware device on the initial stage of developing, the test job will not have great influence.

The device driver plays an important role in an operating system. It is the communication bridge between the hardware peripheral and the application programs running on computer. Device drivers are very sophisticate to develop, because it depends on knowledge of peripheral device specification as well as the OS. kernel’s details. Because a driver is a program which operates in the kernel of OS, it is very sensitive to the modification/upgrade of an OS. Even dealing with the same peripheral device, it usually can not avoid to redevelop a new version of device driver for a newer version of OS. Therefore, the development of device drivers has become a big problem for many PC peripheral system providers. In this thesis, we proposed a device driver generator for PC peripherals using USB interface. More specifically, we focus on the USB force feedback devices. Given the necessary parameters for a specific device, the tool can automatic generate a specific device driver, an INF file and a corresponding application program for verification. This tool can release a software engineer from learning the heavy burden of investigating the operating system core and relevant knowledge of the hardware, hence accelerates the development of the driver. In short, it is a very useful synthesis tool for device driver, which can help many hardware peripheral providers to solve their problem.

Οι ανάγκες της εποχής μας για πληροφορία και επικοινωνία ανά πάσα στιγμή και σε οποιοδήποτε μέρος έχουν οδηγήσει στην ανάπτυξη ολοένα και μικρότερων, αλλά παράλληλα και ισχυρότερων, φορητών συσκευών. Η τελευταία λέξη της τεχνολογίας αφορά υπολογιστές τσέπης (Pocket PC) σε μέγεθος κινητού τηλεφώνου, οι οποίοι φέρουν ισχυρό υπολογιστικό κύκλωμα, πολλαπλές δυνατότητες δικτύωσης/επικοινωνίας και ένα λειτουργικό σύστημα (Windows CE/Windows Mobile) που επιτρέπει την ανάπτυξη πληθώρας εφαρμογών. Ενδεικτικά αναφέρονται μερικές χρήσεις των Pocket PC ως κινητά τηλέφωνα, ως συσκευές αναπαραγωγής πολυμεσικών αρχείων (ήχου/εικόνας), ως προσωπικές ατζέντες, ως συσκευές πλοήγησης κ.ά. Στην διπλωματική εργασία θα περιγράψουμε λεπτομερώς το λειτουργικό σύστημα, τα τεχνικά χαρακτηριστικά των Pocket PC και τις δυνατότητες τους. Επίσης θα παρουσιάσουμε τα περιβάλλοντα υλοποίησης εφαρμογών για τις πλατφόρμες αυτές.
Μια άλλη τεχνολογία που και αυτή έχει εισβάλλει πρόσφατα στη ζωή μας είναι το Σύστημα Εντοπισμού Θέσης (GPS - Global Positiong System). Το GPS χρησιμοποιεί δορυφόρους που βρίσκονται σε τροχιά γύρω από τη Γη για την εύρεση του στίγματος και για την ακριβή μέτρηση χρόνου. Αν και αναπτύχθηκε για στρατιωτικούς σκοπούς, πλέον χρησιμοποιείται κατά κόρον από απλούς πολίτες. Οι εφαρμογές του GPS ποικίλουν από την πλοήγηση μέσα σε μια πόλη μέχρι την ορειβασία και από το κτηματολόγιο μέχρι την ωκεανογραφία. Η τεχνολογία στις μέρες μας επιτρέπει την κατασκευή GPS δεκτών πολύ μικρού μεγέθους και με δυνατότητα επικοινωνίας με διάφορα είδη υπολογιστών, συμπεριλαμβανομένων και των Pocket PC. Με το κατάλληλο πρόγραμμα στο Pocket PC έχουμε τη μοναδική δυνατότητα να επεξεργαζόμαστε εν κινήσει τα χωρικά δεδομένα του δέκτη. Στην εργασία θα περιγράψουμε αρχικά την τεχνολογία του GPS και στην συνέχεια το πρωτόκολλο εξαγωγής δεδομένων από το GPS δέκτη.
Στην τρίτη φάση της εργασίας καλούμαστε στην έμπρακτη υλοποίηση του συνδυασμού των 2 τεχνολογιών. Πιο συγκεκριμένα θα επιχειρήσουμε να υλοποιήσουμε μια Windows Mobile εφαρμογή που θα τρέχει σε ένα Pocket PC και θα χρησιμοποιεί τα δεδομένα από το GPS δέκτη, καθώς και άλλη σχετική πληροφορία, για να καταγράψει την σήμανση του οδικού δικτύου.In our modern society the continuous need for information and communication has led to the development of even smaller, but at the same time and more powerful, mobile devices. State of the art technology introduces pocket computers (Pocket PC) with size similar to a cell-phone, including powerful processing circuits, multiple capabilities of networking and an operating system (Windows CE/Mobile) capable for developing a broad range of applications. Pocket PCs can be used as sophisticated cell-phones, multimedia reproduction devices (picture, sound and video), personal organizers, city navigators and more. In this master thesis, we will describe in detail this operating system, the technical characteristics of Pocket PCs and their capabilities. We will also present the software development kits (SDKs) available for these devices. Another achievement of technology which has invaded recently in our lives is the Global Positioning System (GPS). GPS uses satellites orbiting the earth, to find our current location on Earth and for precise time calculation. At start it had only military use, but nowadays it is used extensively by citizens for civilian purposes. The applications of GPS vary from navigating through a city to oceanography. Modern technology is able to manufacture small GPS receivers with the capability to connect to a number of devices, including Pocket PCs. With the appropriate program running on the Pocket PC, we have the unique possibility to process territorial data on the go. In our thesis we will describe the GPS system and the protocol responsible for exporting data from a GPS receiver.

Full textAbstract:
Mobile devices as smartphones, tablets and laptops, are nowadays considered indispensable objects
by most people in developed countries. A s personal and work assistant s , some of th e s e
devices store , process and transmit sensitive and private data. Naturally , the number of mobile
applications with integrated cryptographic mechanisms or offering security services has been
significantly increasing in the last few years. Unfortunately, not all of those applications are secure
by design, while other may not implement the cryptographic primitives correctly. Even the
ones that implement them correctly may suffer from longevity problems, since cryptographic
primitives that are considered secure nowadays may become obsolete in the next few years.
Rivest, Shamir and Adleman (RSA) is an example of an widely used cryptosystem that may become
depleted shorty . While the security issues in the mobile computing environment may be of
median severity for casual users, they may be critical for several professional classes, namely
lawyers, journalists and law enforcement agents. As such, it is important to approach these
problems in a structured manner.
This master’s program is focused on the engineering and implementation of a mobile application
offering a series of security services. The application was engineered to be secure by design
for the Windows Phone 8.1 Operating System (OS) which, at the time of writing this dissertation,
was the platform with the most discreet offer in terms of applications of this type. The
application provides services such as secure exchange of a cryptographic secret, encryption and
digital signature of messages and files, management of contacts and encryption keys and secure
password generation and storage. Part of the cryptographic primitives used in this work
are from the Elliptic Curve Cryptography (ECC) theory, for which the discrete logarithm problem
is believed to be harder and key handling is easier. The library defining a series of curves
and containing the procedures and operations supporting the ECC primitives was implemented
from scratch, since there was none available, comprising one of the contributions of this work.
The work evolved from the analysis of the state-of-the-art to the requirements analysis and
software engineering phase, thoroughly described herein, ending up with the development of a
prototype. The engineering of the application included the definition of a trust model for the
exchange of public keys and the modeling of the supporting database.
The most visible outcomes of this master’s program are the fully working prototype of a mobile
application offering the aforementioned security services, the implementation of an ECC
library for the .NET framework, and this dissertation. The source code for the ECC library was
made available online on GitHub with the name ECCryptoLib [Ana15]. Its development and
improvement was mostly dominated by unit testing. The library and the mobile application
were developed in C?. The level of security offered by the application is guaranteed via the
orchestration and combination of state-of-the-art symmetric key cryptography algorithms, as the Advanced Encryption Standard (AES) and Secure Hash Algorithm 256 (SHA256) with the ECC
primitives. The generation of passwords is done by using several sensors and inputs as entropy
sources, which are fed to a cryptographically secure hash function. The passwords are stored in
an encrypted database, whose encryption key changes every time it is opened, obtained using
a Password-Based Key Derivation Function 2 (PBKDF2) from a master password. The trust model
for the public keys designed in the scope of this work is inspired in Pretty Good Privacy (PGP),
but granularity of the trust levels is larger.Dispositivos móveis como computadores portáteis, smartphones ou tablets, são, nos dias de hoje, considerados objectos indispensáveis pela grande maioria das pessoas residentes em países desenvolvidos. Por serem utilizados como assistentes pessoais ou de trabalho, alguns destes dispositivos guardam, processam e transmitem dados sensíveis ou privados. Naturalmente, o número de aplicações móveis com mecanismos criptográficos integrados ou que oferecem serviços de segurança, tem vindo a aumentar de forma significativa nos últimos anos. Infelizmente, nem todas as aplicações são seguras por construção, e outras podem não implementar as primitivas criptográficas corretamente. Mesmo aquelas que as implementam corretamente podem sofrer de problemas de longevidade, já que primitivas criptográficas que são hoje em dia consideradas seguras podem tornar-se obsoletas nos próximos anos. O Rivest, Shamir and Adleman (RSA) constitui um exemplo de um sistema criptográfico muito popular que se pode tornar obsoleto a curto prazo. Enquanto que os problemas de segurança em ambientes de computação móvel podem ser de média severidade para utilizadores casuais, estes são normalmente críticos para várias classes profissionais, nomeadamente advogados, jornalistas e oficiais da justiça. É, por isso, importante, abordar estes problemas de uma forma estruturada. Este programa de mestrado foca-se na engenharia e implementação de uma aplicação móvel que oferece uma série de serviços de segurança. A aplicação foi desenhada para ser segura por construção para o sistema operativo Windows Phone 8.1 que, altura em que esta dissertação foi escrita, era a plataforma com a oferta mais discreta em termos de aplicações deste tipo. A aplicação fornece funcionalidades como trocar um segredo criptográfico entre duas entidades de forma segura, cifra, decifra e assinatura digital de mensagens e ficheiros, gestão de contactos e chaves de cifra, e geração e armazenamento seguro de palavras-passe. Parte das primitivas criptográficas utilizadas neste trabalho fazem parte da teoria da criptografia em curvas elípticas, para a qual se acredita que o problema do logaritmo discreto é de mais difícil resolução e para o qual a manipulação de chaves é mais simples. A biblioteca que define uma série de curvas, e contendo os procedimentos e operações que suportam as primitivas criptográficas, foi totalmente implementada no âmbito deste trabalho, dado ainda não existir nenhuma disponível no seu início, compreendendo assim uma das suas contribuições. O trabalho evoluiu da análise do estado da arte para o levantamento dos requisitos e para a fase de engenharia de software, aqui descrita detalhadamente, culminando no desenvolvimento de um protótipo. A engenharia da aplicação incluiu a definição de um sistema de confiança para troca de chaves públicas e também modelação da base de dados de suporte. Os resultados mais visíveis deste programa de mestrado são o protótipo da aplicação móvel, completamente funcional e disponibilizando as funcionalidades de segurança acima mencionadas, a implementação de uma biblioteca Elliptic Curve Cryptography (ECC) para framework .NET, e esta dissertação. O código fonte com a implementação da biblioteca foi publicada online. O seu desenvolvimento e melhoramento foi sobretudo dominado por testes unitários. A biblioteca e a aplicação móvel foram desenvolvidas em C?. O nível de segurança oferecido pela aplicação é garantido através da orquestração e combinação de algoritmos da criptografia de chave simétrica atuais, como o Advanced Encryption Standard (AES) e o Secure Hash Algorithm 256 (SHA256), com as primitivas ECC. A geração de palavras-passe é feita recorrendo utilizando vários sensores e dispoitivos de entrada como fontes de entropia, que posteriormente são alimentadas a uma função de hash criptográfica. As palavras-passe são guardadas numa base de dados cifrada, cuja chave de cifra muda sempre que a base de dados é aberta, sendo obtida através da aplicação de um Password-Based Key Derivation Function 2 (PBKDF2) a uma palavrapasse mestre. O modelo de confiança para chaves públicas desenhado no âmbito deste trabalho é inspirado no Pretty Good Privacy (PGP), mas a granularidade dos níveis de confiança é superior.

The Chinese characters are numerous and complicated. In order to reduce the data volume of various fonts, Windows system uses the vector font of TrueType from composite method. Chinese fonts are usually used in graphic software. However, font translations among some Chinese software packages are incompatible, e.g. the international CorelDraw and domestic graphic software for titles. They do not access the Windows to get the bitmap data, instead they access the data of font dot to display the character. Therefore, the TrueType font from composite method shows the overlay of strokes in many characters. To solve the above problems, is we need to transfer the vector font to outline font of the TrueType font in the Chinese Windows system. This research adopts the mathematical theory of the Bezier curve to describe the outline of font, and uses the graphic user interface of windows system to provide a more user-friendly interface that eliminate the inconvenience of command line interface. The main transfer font is DYNA font, and the thesis also can be applied to other font of composition.

Heterogeneous multicore systems with highly parallel computing are the significant trends for being used to improve the performances of processors in computing. They are provided with some modules for communications between different cores and with different instruction set architectures so that it is difficult to develop applications on such systems. Therefore, we present an integrated development platform for heterogeneous multicore to simplify the application development flow. The architecture of the platform is composed of application layer, abstraction layer and hardware layer. The hardware layer is the heterogeneous multicore system with a master processor and multiple slave coputational units; The abstraction layer is divided into two parts: one is the platform management core on a master processor; the other is the implementor for accelerated functions on each slave coputational unit. The former manages not only resources of accelerated functions and slave coputational units by using semaphore machanism but also shared memory by using dynamic storage management. In addition, it coordinates the communications between different cores by using interrupts and FIFOs; In the application layer, we consider the code to be accelerated on a coputational unit as function-like sub-program, called accelerated function. Therefore, we provide APIs not only on the master processor for caller but also on the slave coputational unit for the callee. Furthermore, we provide an integrator to make a single executable for simplifying implement manner. Finally, we apply the framework of the platform to Windows CE (WinCE) operating system, and we successfully realize it on TI DM3730 processor. Using the procedure of developing applications as examples, we verify that this platform doesn''t affect the total performance, and that it is feasible.

This thesis develops a device driver for a National Instrument (NI) Analog-to-digital conversion (A/D) board to be used in a NI PXI system under the Windows CE environment. The PXI standard is an extension to the popular PCI bus interface tailored to fit hostile instrument usage environment. Even though it posses many rugged elements, the PXI system is not popular among the PC market. The peripheral support around it is therefore very limited. This thesis uses the Platform Builder provided with WinCE to develop the device driver for the NI A/D board. The software is developed under Embedded Visual C++, and the driver is fully compatible for PXI system installation.

With technology advancement, mobile devices prevail among embedded system products. However, many applications can not run directly on mobile devices due to limitation in computing power and platform variety. This thesis implements an X window remote operation system which allows users to access remote applications everywhere through a browser with no plug-in installation required and no other client-end software needed. There are Web ＆ WebSocket Server, X Server Manager, Application Manager, and Input Handler on the server side. The Web ＆ WebSocket Server realize the communication interface between server and clients while X Server Manager, Application Manager, and Input Handler deal with user input and requests from client side. The user interface on the client side is achieved by a web page. The development of this X window remote operation system features four main characteristics. First, the output display produced by remote application is presented by drawing instructions. Forwarding drawing instructions consumes less bandwidth than forwarding pictures of the application output. Second, web browser is used as the unified platform. A drawing library for HTML5 canvas element is implemented which realizes drawing application screen on the web page. Third, server directly pushes screen update information to client. This thesis uses HTML5 WebSocket as the communication protocol between client and server, which allows the connection established by a client to remain open. Fourth, this system supports multiple connections. The connections are isolated and will not interfere with each other. This thesis achieves the goals of decreasing the response latency and reducing the amount of data transferred over network from remote X window operation system. As a result, users can operate remote X window applications easily and smoothly.

Die Arbeit präsentiert ein Multimedia-Framework für Linux, das im Unterschied zu früheren Arbeiten auf den Ideen "retained-mode processing" und "lazy evaluation" basiert: Statt Transformationen unmittelbar auszuführen, wird eine abstrakte Repräsentation aller Medienelemente aufgebaut. "renderer"-Treiber fungieren als Übersetzer, die diese Darstellung zur Laufzeit in konkrete Operationen umsetzen, wobei das Datenmodell zahlreiche Optimierungen zur Reduktion der Anzahl der Schritte oder der Minimierung von Kommunikation erlaubt. Dies erlaubt ein stark vereinfachtes Programmiermodell bei gleichzeitiger Effizienzsteigerung. "renderer"-Treiber können zur Ausführung von Transformationen den lokalen Prozessor verwenden, oder können die Operationen delegieren. In der Arbeit wird eine Erweiterung des X Window Systems um Mechanismen zur Medienverarbeitung vorgestellt, sowie ein "renderer"-Treiber, der diese zur Delegation der Verarbeitung nutzt.
