Study of Automated Trust Negotiation Mechanism Based on Cache Sequence Game in P2P Environment

Chunzhi Wang, Ruoxi Wang, Hongwei Chen and Ya Huang


The process of trust negotiation is the one of the resource requester and resource provider exposing the certificate set and strategy set with each other. The network authentication model based on trust negotiation fulfills the P2P network security, privacy, efficiency and success. The negotiation model will be constructed by the trust game tree. When the negotiation succeeds, cache the certificate sequence and directly show the sequence to complete the negotiation in the next negotiation. But the complete caching sequence will lead a heavy burden and cause safety problems to the system, splitting negotiation process into multi-step and caching part of sequence to improve overall performance. This study builds the caching sequence model based on mixed static game theory and simulates the situation of the caching sequence on partial by introducing the ratio factor. Finally, verify the assumption via the simulation tools named Gambit.
