A P2P File Sharing and Exchange Protocol Providing Receiver Anonymity and File Validation in Mobile Ad-Hoc Networks

Abstract

With the increasing popularity of P2P file sharing and advancement of mobile technologies, mobile P2P has revealed its attraction. Anonymity has become an increasing requirement in mobile networks. To reduce the garbage file which is sent to receiver, tile validation is another requirement in the mobile P2P environment. Both the anonymity and file validation issues have not been addressed very well. In this paper, we will analyze the security and anonymity in P2P file sharing and exchange system in mobile ad hoc environment, and we will propose a protocol which can provide receiver anonymity by using secret sharing and the file validation by the file's fingerprint. To choose the best one from several responders, we also import the trust table to evaluate every responder.
