Automated Validation of Internet Security Protocols and Applications[AVISPA]

  The AVISPA Tool provides a suite of applications for building and analyzing formal models of security protocols. Protocol models are written in the  High Level Protocol Specification Language, or HLPSL .  It  aims at developing a push-button, industrial-strength technology for the analysis of large-scale Internet security-sensitive protocols and applications. Also  provides a modular and expressive formal language for specifying protocols and their security properties, and integrates different back-ends that implement a variety of state-of-the-art automatic analysis techniques. Experimental results, carried out on a large library of Internet security protocols, indicate that the AVISPA tool is the state of the art for automatic security protocols. No other tool combines the same scope and robustness with such performance and scalability. With the spread of the Internet and network-based services and the development of new technological possibilities, the numbe...

Satellite Network Simulation In NS

 Hi,  This post is to show how we can simulate a satellite network in Network Simulator. Some extensions can enable ns to model; Traditional geostationary ``bent-pipe'' satellites with multiple users per uplink/downlink and asymmetric links. Geostationary satellites with processing payloads (either regenerative payloads or full packet switching). Polar orbiting LEO constellations such as Iridium and Teledesic.  These satellite models are principally aimed at using ns to study networking aspects of satellite systems; in particular, MAC, link layer, routing, and transport protocols.
