Abstract	Network coding has been demonstrated to be able to improve the performance of P2P content distribution. However, it is vulnerable to pollution attacks, leading to substantial performance degradation. Moreover, existing corruption detection schemes for network coding are not applied well to P2P systems. More efficient scheme based on attacker identification is required to thwart such attacks. In this paper, we propose an integrated system solution for secure P2P content distribution based on network coding, referred to as ISNC. In ISNC, we first design our system architecture based on extended uniform bipartite networks that can achieve high throughput with network coding. Based on the architecture, we present a secure network coding signature scheme and an identity-based malicious peer identification scheme. The two schemes can cooperate to thwart pollution attacks effectively in P2P network, not only detecting corrupted blocks, but also identifying all the malicious peers. Simulation results show that ISNC can effectively limit the pollution spread and identify malicious peers quickly, even when they collude to launch attacks. Compared with existing related schemes, ISNC is especially applicable for P2P content distribution, and can achieve both high security and overall efficiency.
