Toward Testing Security Attacks and Defense Mechanisms for P2PSIP in MANETs with a Simulator

Mobile Ad hoc NETworks (MANETs) are comprised of mobile devices communicating with each other over multi-hop wireless links. Because they do not require any fixed infrastructure, these networks are appropriate for communication in military operations, for example. The Session Initiation Protocol (SIP) is a standard for session establishment in Voice over IP context, notably, but is not adapted to MANETs and peer-to-peer (P2P) networks. Though solutions have been proposed, their security properties are not addressed in depth. We thus analyze the different threats affecting a military MANET used for P2PSIP, propose a security solution, based in large part on cryptographic challenges, to counter the identified threats and present some simulation-based experiment results for our proposed solution.
