To achieve anonymous communication in moblie P2P networks

Privacy and anonymity have become an increasing requirement in today's wireless networks. However, current mobile peer-to-peer architectures have not taken into account anonymity, especially the mutual anonymity between two nodes. In this paper, we propose a Secure-Information-Dispersal-Algorithm-based Mutual anonymity protocol (SIDAM), for mobile P2P networks. SIDAM achieves mutual anonymity in mobile P2P networks. We simulate SIDAM in a prototyped test-bed and initiate comprehensive attacks on our protocol. The simulation results indicate that SIDAM provides high anonymity with a low cryptography processing overhead.
