%X The anonymity, self-organization and dynamicity of P2P networks make P2P-based viruses and Trojan prevalent, which pose threats to Internet security. P2P trust models can effectively abate this situation and settle many security problems. This paper intended to present a more effective trust model against the defects of current trust models. And presented a new time-space based trust model which made use of DyTrust model and took space into account additionally. Theoretical analysis and simulation experiment show that the time-space based trust model is effective on modeling dynamic trust relationships and resisting attacks.
