Die heutige Informationsgesellschaft hat die Formen des menschlichen Handelns in vielen Bereichen des taeglichen Lebens veraendert. Die Moeglichkeit, Informationen über das Internet auszutauschen, draengt konventionelle Kommunikationsformen immer mehr in den Hintergrund. Gerade in den Bereichen eBusiness und ePayment, welche aufgrund der zunehmenden Globalisierung unabdingbar sind, spielen dabei die Sicherheit und die Authentitaet der uebertragenen Daten eine wichtige Rolle.

This thesis is about the theory behind and software development of TDE View. The application produces a graphical presentation containing graphical objects, such as charts and tables, which display real time data derived from online and currently available services in Swedbank. TDE View is a long term replacement of the previous solution, TDE System Monitor, the purpose of TDE View is to provide the ability to preview the aforementioned features online instead of local deployment. Moreover, the thesis will cover aspects regarding concepts and ideas in transferring data from different hosts in

Abstract:

In this project you can find a study about different encryption algorithms, which are use to safeguard the information on messages over the network. We have developed a client-server application which will send information through the network which has to be secured. There are two kinds of encryption algorithms, the symmetric and the asymmetric key algorithms. Both were used to establish the communication, the asymmetric algorithm (RSA) is used to set up a symmetric key and then, all the communication process is done only with the symmetric algorithm (Blowfish).<br>En este proyecto encontraras

This adaptation of the RSA encryption process was devised to be used on any type of data file, binary as well as text. In the process of developing this computer system, software tools were constructed that allow the exploration of the components of the RSA encryption algorithm. The RSA algorithm was further

Abstract:

In the digital world of today, information is always at risk regardless of its state, at rest or in transit. Cryptography is the technology that promises to address the security issues that emerge. Hence, it was a reasonable consequence to introduce cryptography to databases. However, manually encrypting and decrypting data along with the key management is a burden for the regular user of a database. The need for removing this burden gave birth to Transparent Data Encryption (TDE). TDE technology is widely available nowadays and a number of vendors have developed their own solutions for prot

Telemetry data has great value, as setting up a framework to collect and gather it involve significant costs. Further, the data itself has product diagnostic significance and may also have strategic national security importance if the product is defense or intelligence related. This potentially makes telemetry data a target for acquisition by hostile third parties. To mitigate this threat, data security principles should be employed by the organization to protect telemetry data.

Abstract:

This thesis examines a variety of arithmetic coding encryption schemes proposed in existing literature and the attacks against these schemes. A classification scheme for arithmetic coding encryption schemes is proposed and a new adaptive brute-force attack is described. Under certain conditions, it is shown that an adaptive brute-force attack is capable of recovering the key. The way in which the arithmetic coding encryption scheme is initialized appears to make a significant difference to the security of the system as a whole.

Abstract:

Wireless sensor networks have become increasingly popular in many applications such as environment monitoring and law enforcement. Data aggregation is a method used to reduce network traffic but cannot be used together with conventional encryption schemes because it is not secure and introduces extra overhead. Homomorphic encryption is an encryption scheme that allows data processing on encrypted data as opposed to plaintext. It has the benefit that each intermediate node does not have to decrypt each packet, but the resulting cyphertext is usually much larger than the original plaintext. This

Abstract:

Even if an encryption algorithm is mathematically strong, humans inevitably make for a weak link in most security protocols. A sufficiently threatening adversary will typically be able to force people to reveal their encrypted data. Methods of deniable encryption seek to mend this vulnerability by allowing for decryption to alternate data which is plausible but not sensitive. Existing schemes which allow for deniable encryption are best suited for use by parties who wish to communicate with one another. They are not, however, ideal for personal data storage.

Abstract:

Large-scale data management systems rely more and more on cloud storage, where the need for efficient search capabilities clashes with the need for data confidentiality. Encryption and efficient accessibility are naturally at odds, as for instance strong encryption necessitates that ciphertexts reveal nothing about underlying data. Searchable encryption is an active field in cryptography studying encryption schemes that provide varying levels of efficiency, functionality, and security, and efficient searchable encryption focuses on schemes enabling sub-linear (in the size of the database) sear

Abstract:

Since the 1970s, a large number of encryption schemes have been proposed, among which some have been standardised and widely adopted all over the world, such as data encryption standard (DES) and advanced encryption standard (AES). However, due to the special features of three-dimensional (3D) content, these encryption standards are not a suitable solution for 3D ap- plications. The problem of 3D content encryption is beyond the application of established and well-known encryption algorithms. This is primarily due to the structure of 3D content and the way it is used commercially. Unlike data
