Abstract:

Zusammenfassung. Das Zusammenspiel von negativem Affekt und nachfolgender Affektregulation auf das Essverhalten wurde mit 70 Versuchspersonen (Vpn) experimentell untersucht. Nach einer Imaginationsinduktion von negativem Affekt wurden die Vpn in eine positive oder in eine negative Selbstaktivierungsgruppe eingeteilt. Die Diätintention der Probanden wurde durch eine “Neujahrsvorsatz-Methode“ erfasst. Es ergaben sich folgende Interaktionen zwischen Selbstaktivierung und Diätintention: (a) Vpn mit negativer Selbstaktivierung und niedriger Diätintention aßen mehr Schokolade als Vpn in allen anderen Bedingungen. (b) Vpn mit positiver Selbstaktivierung und hoher Diätintention aßen mehr Kekse als Vpn in allen anderen Bedingungen. Die Befunde sind nicht mit der Hypothese von Tice, Bratslavsky und Baumeister (2001) vereinbar, die eine einfache Beziehung zwischen negativem Affekt und nachfolgendem Verlust der Impulskontrolle beim Essen postulierten. Es gab darüber hinaus positive Korrelationen zwischen der Menge der verzehrten Schokolade und Persönlichkeitsdispositionen mit Beziehung zu Depressivität. Implikationen der Befunde für eine Diät und die Gesundheit werden diskutiert.

Abstract:

Zusammenfassung: Sechsundsechzig Studierende nahmen an einem computer-basierten Training motivationaler Lernstrategien teil. Gegenstand des Trainings war eine Strategie, eine Lernabsicht zu entwickeln, indem man sich den persönlichen Nutzen des zu erwerbenden Wissens verdeutlicht. Die Vpn erhielten (1) kein spezifisches Training, (2) nur ein Training der motivationalen Lernstrategie oder (3) ein kombiniertes Training der Lernstrategie und darauf bezogener Selbstregulation. Nach dem Training bearbeiteten die Vpn einen Lehrtext, den sie zuvor als weniger motivierend beurteilt hatten. Es wurde erhoben, inwieweit die Vpn die Trainingsinhalte zur Anwendung brachten, welches Motivationsniveau sie bei Anwendung der gelernten Strategie erreichten und wie viel Wissen sie aus der Bearbeitung des Textes gewannen. Die Vpn des kombinierten Trainings schnitten hinsichtlich aller drei Variablen besser ab als die Vpn des Lernstrategietrainings und die Vpn ohne Training, und die Vpn des Lernstrategietrainings schnitten ebenfalls besser ab als die Vpn ohne Training. Die Ergebnisse entsprechen aktuellen Theorien des Trainings von Lernstrategien, die davon ausgehen, dass es sinnvoll ist, neben der Vermittlung von Wissen über einzelne Lernstrategien auch den zielführenden Einsatz der jeweiligen Lernstrategie zu trainieren.

Abstract:

Zusammenfassung: Die Untersuchung galt der Frage, welche Bedeutung ausschließlich den Körper- und Gliederbewegungen des Menschen in face-to-face Situationen bei der Eigenschaftsattribution zukommt. Hierzu wurde das Verfahren der Skriptanimation eingesetzt, womit sich die entsprechenden Bewegungen von anderen normalerweise zur Verfügung stehenden Informationen isolieren und auf eine Computerpuppe übertragen lässt. Insgesamt 153 Versuchspersonen nahmen an drei Versuchsreihen teil und beurteilten nacheinander 12 verschiedene Fernsehakteure: 55 Vpn beurteilten die Originalaufzeichnung der Akteure; 33 Vpn beurteilten die originalgetreu reanimierten Körper- und Gliederbewegungen der Darsteller; 65 Vpn beurteilten die im Bewegungsablauf modifizierten Animationen. Als Beurteilungsinstrument wurden Ratingskalen eingesetzt. Die Ergebnisse veranschaulichen, dass die Eliminierung bzw. Konstanthaltung aller Begleit- und Kontextinformationen keinen systematischen Einfluss auf die Eigenschaftsattributionen ausübte. Andererseits genügten bereits kleine Modifikationen im Bewegungsablauf der Kopf- und Rumpfbewegungen, damit sich das Bild, das sich die Vpn von den dargestellten Personen machten, auf nahezu allen Urteilsskalen entweder verbesserte oder verschlechterte. Die Ergebnisse werden mit Erkenntnissen aus Multikanalanalysen nonverbalen Verhaltens in Zusammenhang gebracht.

Abstract:

Epizootic hemorrhagic disease virus (EHDV) is a Culicoides transmitted orbivirus that causes haemorrhagic disease in wild and domestic ruminants. A collection of 44 EHDV isolated from 2008 to 2012 was fully sequenced and analysed phylogenetically. Serotype 2 viruses were the dominant serotype all years except 2012 when serotype 6 viruses represented 63 % of the isolates. High genetic similarity (>94 % identity) between serotype 1 and 2 virus VP1, VP3, VP4, VP6, NS1, NS2 and NS3 segments prevented identification of reassortment events for these segments. Additionally, there was little genetic diversity (>96 % identity) within serotypes for VP2, VP5 and VP7. Preferential reassortment within the homologous serotype was observed for VP2, VP5 and VP7 segments for type 1 and type 2 viruses. In contrast, type 6 viruses were all reassortants containing VP2 and VP5 derived from an exotic type 6 with the remaining segments most similar to type 2 viruses. These results suggest that reassortment between type 1 and type 2 viruses requires conservation of the VP2, VP5 and VP7 segment constellation while type 6 viruses only require VP2 and VP5 and are restricted to type 2-lineage VP7. As type 6 VP2 and VP5 segments were exclusively identified in viruses with type 2-derived VP7, these results suggest functional complementation between type 2 and type 6 VP7 proteins.

Abstract:

Virtual private network (VPN) gateways are widely applied to provide secure end-to-end remote access and to relay reliable interconnected communication in cloud computing. As network convergence nodes, the performance of VPN gateways is limited by traditional methods of packet receiving and sending, the kernel protocol stack and the virtual network interface card. This paper proposes a generic high-performance architecture (GHPA) for VPN gateways in consideration of its generality and performance. In terms of generality, we redesign a generic VPN core framework by modeling a generic VPN communication model, formulating generic VPN core technologies and presenting corresponding core algorithms. In terms of performance, we propose a three-layer GHPA for VPN gateways by designing a VPN packet processing layer based on a data plane development kit (DPDK), implementing a user space basic protocol stack and applying our proposed generic VPN core framework. On the basis of the research work above, we implement a high-performance VPN (HP-VPN) and a traditional VPN (T-VPN) that complies with GHPA and traditional methods, respectively. Experimental results prove that the performance of HP-VPN based on GHPA is superior to T-VPN and other common VPNs in RTT, system throughput, packet forwarding rate and jitter. In addition, GHPA is extensible and applicable for other VPN gateways to improve their performance.

Abstract: A VPN is an essential tool for securing your personal data and protecting your privacy online. We’ve put together the ultimate guide to VPNs to show you what a VPN does, how VPNs work, and how they protect you. Learn how to choose the right VPN, or secure your privacy right now by downloading our own powerful and lightning-fast VPN app. A VPN works by using encryption protocols to funnel all your internet traffic through an encrypted tunnel a virtual private network between your computer and a remote VPN server. This hides your IP address and secures your data, preventing others from intercepting it. Without a VPN, all your internet traffic is potentially exposed to your internet service provider (ISP), the government, advertisers, or other people on your network. That’s why VPN connections boost your privacy and security online. VPN is virtual because it’s created digitally there isn’t a physical cable that reaches from your device directly to the VPN server.

Abstract:

The ever-increasing internet is an ISP challenge for the future of the expected global computer network traffic and QoS needs. To maintain competitive ISPs in Indonesia with the development of internet usage, the demand for QoS must be increased. MPLS VPN networks combine layer 2 switching technology with layer 3 routing technology. MPLS VPN networks have emerged as technologies that meet VPN requirements such as private IP, and the ability to support overlapping addresses in resolving speed and QoS problems. The method used is experimental research. From the measurement results obtained by VPN and MPLS VPN network delay has a very good delay value. For throughput on VPN networks have medium quality and MPLS VPN networks have good quality. And for the packet loss value for both types of networks is 0%. This shows that MPLS VPN network throughput has better QoS while for delay and packet loss on VPN and MPLS VPN networks have the same quality value.

Abstract:

Banna virus (BAV) is the type species of the genus Seadornavirus within the family Reoviridae. The Chinese BAV isolate (BAV-Ch), which causes encephalitis in humans, was shown to have a structural organization and particle morphology reminiscent of that of rotaviruses, with fibre proteins projecting from the surface of the particle. Intact BAV-Ch virus particles contain seven structural proteins, two of which (VP4 and VP9) form the outer coat. The inner (core) particles contain five additional proteins (VP1, VP2, VP3, VP8 and VP10) and are ‘non-turreted’, with a relatively smooth surface appearance. VP2 is the ‘T=2’ protein that forms the innermost ‘subcore’ layer, whilst VP8 is the ‘T=13’ protein forming the core-surface layer. Sequence comparisons indicate that BAV VP9 and VP10 are equivalent to the VP8* and VP5* domains, respectively, of rotavirus outer-coat protein VP4 (GenBank accession no. P12976). VP9 has also been shown to be responsible for virus attachment to the host-cell surface and may be involved in internalization. These similarities reveal a previously unreported genetic link between the genera Rotavirus and Seadornavirus, although the expression of BAV VP9 and VP10 from two separate genome segments, rather than by the proteolytic cleavage of a single gene product (as seen in rotavirus VP4), suggests a significant evolutionary jump between the members of these two genera.

Abstract:

Software-Defined Wide Area Networks (SD-WANs) are an emerging Software-Defined Network (SDN) technology to reinvent Wide Area Networks (WANs) for ubiquitous network interconnections in cloud computing, edge computing, and the Internet of Everything. The state-of-the-art overlay-based SD-WANs are simply conjunctions of Virtual Private Network (VPN) and SDN architecture to leverage the controllability and programmability of SDN, which are only applicable for specific platforms and do not comply with the extensibility of SDN. This paper motivates us to refactor traditional VPNs with SDN architecture by proposing an overlay-based SD-WAN solution named Software-Defined Virtual Private Network (SD-VPN). An SDN-based auto-constructed VPN model and its evaluating metrics are put forward to automatically construct overlay WANs by node placement and service orchestration of SD-VPN. Therefore, a joint placement algorithm of VPN nodes and algorithms for overlay WAN service loading and offloading are proposed for SD-VPN controllers. Finally, a three-layer SD-VPN system is implemented and deployed in actual network environments. Simulation experiments and system tests are conducted to prove the high-efficiency controllability, real-time programmability, and auto-constructed deployability of the proposed SD-VPN. Performance trade-off between SD-VPN control channels and data channels is evaluated, and SD-VPN controllers are proven to be extensible for other VPN protocols and advanced services.

Abstract:

Multiprotocol Label Switching (MPLS) is effective in managing and utilizing available network bandwidth. It has advanced security features and a lower time delay. The existing literature has covered the performance of MPLS-based networks in relation to conventional Internet Protocol (IP) networks. But, too few literatures exist on the performance of MPLS-based Virtual Private Networks (VPN) in relation to traditional VPN networks. In this paper, a comparison is made between the effectiveness of the MPLSVPN network and a classic VPN network using simulation studies done on OPNET® . The performance metrics used to carry out the comparison include; End to End Delay, Voice Packet Sent/Received and Label Switched Path’s Traffic. The simulation study was carried out with Voice over Internet Protocol (VoIP) as the test bed. The result of the study showed that MPLS-based VPN networks outperform classic VPN networks.

Abstract:

Virtual Private Network (VPN) is a private network that uses public network to tunnel the connection from the users’ end to the VPN server. VPN allows users to create a secure connection to another network over the public Internet. VPNs can be used to shield users’ browsing activity and encrypts data transmitted over the network to prevent sniffing attack. Nowadays, users can either pay a premium price for a good VPN service or risk their privacy using free browser-based VPN. Thus, SafeSearch is developed to address these issues in mind. With SafeSearch, users will not need to fork out a lot of money for premium VPN subscription services or expose themselves to targeted advertising when utilising free browser-based VPN. In this study, open VPN protocol was used to create the VPN server on a microcomputer called Raspberry Pi. The software used was mostly open-source except for the VPN client. Obfuscation technique was used to hide VPN traffic by disguising it as just another normal Internet traffic against Deep Packet Inspection when passing through firewall. After the VPN server was established, tests were carried out to evaluate the functionality and reliability of the VPN server in “real-world” environment. The tests conducted were network restriction penetration assessment, network performance and user acceptance test. Penetration assessment result showed that SafeSearch is capable of bypassing web filtering and deep packet inspection. Network performance during SafeSearch connection has slight latency and bandwidth decline, although it is not overly affected. The outcome of the user acceptance test was positive as the majority of participants of the study were confident that SafeSearch can secure their connection and protect their privacy when browsing the web. To conclude, both objectives of this project were fully achieved and the scope of study was followed thoroughly.

Abstract:

Bluetongue virus (BTV) is the type species os the genus orbivirus in the family Reoviridae. The virus has a fibrillar outer coat containing two major structural proteins VP2 and VP5 which surround an icosahedral core. The core contains two major proteins VP3 and VP7 and three minor proteins VP1, VP4 and VP6. Recent evidence has indicated that the core comprises a neucleoprotein center which is surrounded by two protein layers; VP7, a major constituent of capsomeres comprises the outer and VP3 the inner layer of the core . Antibodies to VP7 are currently used in enzyme-linked immunosorbant assays and immuno-electron microscopical (JEM) tests for the detection of BTV. The tests involve the antibody recognition of VP7 on virus particles. In an attempt to understand how complete viruses can interact with antibodies to VP7 various antibody types and methodologies were utilized to determine the physical accessibility of the core to the external environment.

By analyzing the problems of IPSec VPN, in terms of improving safety performance, the combination of PKI and IPSec VPN program was proposed. Theoretical analysis shows that such program can indeed solve the problem of authentication imperfect, thus improving the safety performance of the network.

VPN dapat terjadi antara dua PC atau bisa juga antara dua atau lebih jaringan yang berbeda. VPN dapat dibentuk dengan menggunakan teknologi tunneling dan encryption. Server OpenVPN menghasilkan profil jaringan terenkripsi, kemudian semua pengguna dapat membentuk jaringan VPN dan mereka dapat menggunakan layanan organisasi seolah-olah mereka secara geografis berada di tempat yang sama, konfigurasi ini juga memungkinkan penggunaan layanan atau aplikasi eksternal apa pun tanpa memengaruhi keamanan organisasi, VPN dapat berjalan pada IPv6 dan IPv4, dengan kelebihan yang banyak OpenVPN melintasi NAT (Network Address Translation). Jaringan VPN ini dibuat untuk memudahkan pekerja yang sedang melaksanakan aktivitas WFH (Work From Home) VPN sebuah koneksi virtual yang bersifat private dan tidak semua orang bisa mengaksesnya. Implementasi VPN dapat mempermudah komunikasi data jarak jauh tanpa khawatir ada tabrakan data, karena dengan menggunakan jaringan virtual ini dapat terhubung secara bersamaan. Dengan VPN, pengguna mempunyai keamanan data yang lebih dibandingkan dengan menggunakan jaringan lokal biasa. Ketika pengguna terhubung ke jaringan VPN maka akan mempunyai IP yang berbeda dengan IP Physical dibuktikan dengan tool tracert terlihat IP dan hoop. Raspberry Pi berfungsi untuk membuat sertifikat VPN client, karena fungsi tersebut tidak digabungkan ke dalam VPS Server karena masalah keamanan jaringan.

Abstract:

This paper presents the design and deployment of a remote access VPN function in CloudStack, an open-source platform for virtualized cloud management. The Remote Access VPN offers secure connectivity for remote users to communicate with virtual machines (VMs) within guest networks. Users can safely connect to cloud-based systems from external networks by using a VPN that uses L2TP-over-IPsec as the underlying protocol. With certain routing mechanisms that guarantee that only guest network traffic is routed through the VPN, the feature supports both "Road Warrior" (dynamic IP clients) and "Site-to-Site" (pre-configured IP clients) VPN connections. In addition to discussing upcoming scalability and usability improvements, this paper covers the technical design, implementation, and testing strategies for the Remote Access VPN feature.

Abstract:

Rotaviruses (RVs) are a major etiological agent of acute viral gastroenteritis in humans and young animals, with rotavirus B (RVB) often detected in suckling and weaned pigs. Group A rotavirus classification is currently based on the two outer capsid proteins, VP7 and VP4, and the middle layer protein, VP6. Using RVB strains generated in this study and reference sequences from GenBank, pairwise identity frequency graphs and phylogenetic trees were constructed for the eleven gene segments of RVB to estimate the nucleotide identity cutoff values for different genotypes and determine the genotype diversity per gene segment. Phylogenetic analysis of VP7, VP4, VP6, VP1–VP3, and NSP1–NSP5 identified 26G, 5P, 13I, 5R, 5C, 5M, 8A, 10N, 6T, 4E, and 7H genotypes, respectively. The analysis supports the previously proposed cutoff values for the VP7, VP6, NSP1, and NSP3 gene segments (80%, 81%, 76% and 78%, respectively) and suggests new cutoff values for the VP4, VP1, VP2, VP3, NSP2, NSP4, and NSP5 (80%, 78%, 79%, 77% 83%, 76%, and 79%, respectively). Reassortment events were detected between the porcine RVB strains from our study. This research describes the genome constellations for the complete genome of Group B rotaviruses in different host species.

Abstract:

Encryption Protocols e.g., HTTPS is utilized to secure the traffic between servers and clients for YouTube and other video streaming services, and to further secure the communication, VPNs are used. However, these protocols are not sufficient to hide the identity of the videos from someone who can sniff the network traffic. The present work explores the methodologies and features to identify the videos in a VPN and non-VPN network traffic. To identify such videos, a side-channel attack using a Sequential Convolution Neural Network is proposed. The results demonstrate that a sequence of bytes per second from even one-minute sniffing of network traffic is sufficient to predict the video with high accuracy. The accuracy is increased to 90% accuracy in the non-VPN, 66% accuracy in the VPN, and 77% in the mixed VPN and non-VPN traffic, for models with two-minute sniffing.

Abstract:

    Working remotely or what we know as Work From Anywhere is still a trend after the COVID-19 pandemic. Working from anywhere and anytime can increase productivity and reduce transportation costs, and is accompanied by fast internet support, good communication and collaboration platforms so this is very popular and in demand. When implementing WFA, it has its own challenges, namely data security. Not all organizations are supported by a reliable IT infrastructure that can protect employee data during WFA. One of the security system technologies that can be used during WFA is VPN. Currently there are many VPN protocols that can be used for WFA. However, in implementing a VPN network, there are several things that must be considered to ensure that the VPN network is successful and functional, such as security, choosing the right architecture, selecting technology and protocols, scalability, quality of service, management and monitoring, as well as security and privacy policies. ZeroTier is a next-generation VPN that is easy to configure, can support multiple devices, and uses an end-to-end connection, eliminating the need for a centralized VPN server. In implementing VPN ZeroTier the method used is the Network Development Life Cycle (NDLC). This methodology is used to plan, implement, and manage a VPN network with ZeroTier to function according to WFA needs.

Abstract:

Abstract: A strong IP technology that builds a secure and encrypted connection tunnel over the less secure internet is required by the majority of enterprise organizations. Joint location and link connectivity issues must be resolved for distant users and branch offices to have secure access to corporate applications and other resources. This ensures security while data passes over encrypted tunnels. Despite the development of IP-based VPN, JLP and LCP for VPN customer edge devices and provider edge nodes have not yet been completely investigated. The purpose of this work is to apply cutting-edge viewpoints to VPN-IP design that may be used in IP multi-protocol label switching (MPLSVPN) infrastructure for cloud computing. The system architecture includes mathematical formulas. End-to-end delay, throughput, and resource consumption behavior for IP tunneling are seen to behave moderately for low scale workloads. While showcasing the benefits of an MPLS-based IP-based VPN architecture, the difficulties of VPN-IP tunneling are explored. This study suggests cloud-based MPLS-VPN as a workable substitute for traditional VPN-IP tunneling in order to get the best performance and service delivery

Abstract:

In an era marked by technological advancement, the rising reliance on Virtual Private Networks (VPNs) necessitates sophisticated forensic analysis techniques to investigate VPN traffic, especially in mobile environments. This research introduces an innovative approach utilizing Convolutional Neural Networks (CNNs) and Graph Neural Networks (GNNs) for classifying VPN traffic, aiding forensic investigators in precisely identifying applications or websites accessed via VPN connections. By leveraging the combined strengths of CNNs and GNNs, our method provides an effective solution for discerning user activities during VPN sessions. Further extending this framework, we incorporate blockchain technology to meticulously record all mobile VPN transactions, ensuring a tamper-proof and transparent ledger that significantly bolsters the integrity and admissibility of forensic evidence in legal scenarios. A specific use-case demonstrates this methodology in mobile forensics, where our integrated approach not only accurately classifies data traffic but also securely logs transactional details on the blockchain, offering an unprecedented level of detail and reliability in forensic investigations. Extensive real-world VPN dataset experiments validate our approach, highlighting its potential to achieve high accuracy and offering invaluable insights for both technological and legal domains in the context of mobile VPN usage.
