METHOD, DEVICE, SYSTEM, CLIENT NODE, PEER NODE AND CONVERGENT POINT FOR PREVENTING NODE FROM FORGING IDENTITY

摘要

In the field of overlay network, a method, a device, a system, a client node, a peer node and a convergent point for preventing a node from forging ID in a P2P network are provided, so as to solve the problems of high overhead and long delay in the existing technical solution for preventing node cheating. The method includes the following steps. After a client node finds a peer node serving the client node, at least one of the client node and the peer node performs ID authentication. After the authentication succeeds, the client node or the peer node establishes an ID anti-forgery log about the other party. The invention is widely applicable to ID authentication for network equipment in a P2P network.
