Poisoning attacks on Peer-to-Peer (P2P) networks are common nowadays. Poisoning refers to the condition in which malicious peers share corrupt or infected content in an attempt to destabilize the system and waste network bandwidth. By so doing, regular peers find less value in the P2P network and get discouraged from participating in the system. This problem can be thwarted by introducing mechanisms to verify the integrity of the downloaded content. However, this requires extra resources for
