A behavior-based trust model in P2P

P2P networks, also known as peer to peer network , enabling network-based P2P nodes dynamic, anonymity, scalability, etc. The security of the network caused a severe challenge. This paper introduces the traditional PKI system to authenticate the credibility of the node s based on the further introduction of the behavioral characteristics of the nodes, according to the node transactions to classify the different behaviors, according to punish, to further improve the reliability of the system.
