Abstract

We consider the problem of anonymous file exchange in wireless ad-hoc networks. We propose a new protocol, dubbed RASH (roam and share), to address the problem. RASH is a peer-to-peer (P2P) protocol which fulfills three objectives: (a) protection of user privacy (understood as the confidentiality of their interests), (b) support for a high degree of file authentication and integrity (to reduce or eliminate false downloads and spoofs), and (c) enforcement of reciprocity (to remove freeloaders from the system). The environment of our scheme is purely ad-hoc, in that it does not assume pre-established trust, fixed-infrastructure, or the existence of specialized nodes
