Abstract

In this paper, we propose a group-based trust model named F-PKI (Freely organized one level Public Key Infrastructure) in P2P system based on Trusted Computing (TC) technology which is used to enhance PC security by incorporating hardware platform. In this model, peers are organized freely by group, each of which is a one level PKI. Preliminary evaluation results show that the proposed model is realistic and argue that not only the security of the trust model proposed is enhanced, but also facilitates authentication and trust establishment between peers in P2P systems. Simulation results show that the service selection success ratio is greater than 0.9 even when there are 50% malicious peers.
