Research ArticleOpen accessIn the abstractIntegration of Quantum Cryptography through Satellite Networks TransmissionSkander Aris, Abderraouf Messai, Malek Benslama et al.Problem statement: The security of the telecommunications satellite has become a crucial issue. The telecommunications can be set using the classical cryptography. But this so-called classical cryptography provides cryptographic security. This means that security is based on the difficulty of some mathematics problems. On the other hand, quantum cryptography provides security without conditions based on the law of quantum physics. … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Framework for Group Key Management Protocol Assessment Independent of View SynchronyDavid Manz, Paul Oman, Jim Alves-FossProblem statement: As group key management extended into the area of large dynamic networks, complex issues emerged involving the many operations that run over several network topologies. The issues that occurred due to multiple topologies were also compounded by differing views of the network, taken at different time slices or positions within the network. This was especially complex when figuring … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 6,942 accessesView PDFCite
Research ArticleOpen accessIn the abstractBluetooth Wireless Network Authentication Using Radio Frequency Communication ProtocolGhossoon M. Waleed, M. Faizal, R. B. Ahmad et al.Problem statement: Bluetooth has emerged as very popular ad hoc network standard today. Bluetooth network applications include wireless synchronization, e-mail/internet/intranet access using local personal computer connections, hidden computing through automated applications and networking.

Research ArticleOpen accessIn the abstractA New Enhancement for Security Mechanism in RoutersKhalid Khanfar, Riyad Khanfar, Walid Al-Ahmad, Eyas El-QawasmehProblem statement: Routers are very important components in any network. They control and organize the in-bound traffic and the out-bound traffic. Controlling a router by an intruder leaves the entire network unsecured. In different studies, Router security was discussed from different aspects such as the routing protocol, the firewall. In this research, we present a new effective security mechanism for … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 7,172 accessesView PDFCite
Research ArticleOpen accessIn the abstractArithmetic Encoding Based Dynamic Source Routing for Ad-Hoc NetworksAjay Koul, R. B. Patel, V. K. BhatAn ad hoc network is a collection of mobile stations forming a temporary network without the aid of any centralized coordinator. Routing messages are an essential component of Mobile Adhoc Networks, as each packet needs to be passed quickly through intermediate nodes from source to destination.
