Abstract: To deal with trust negotiation in the heterogeneous platform composed of non-trusted computing and trusted computing platforms in Peer-to-Peer(P2P) system, a novel trust model is proposed based on Trusted Computing(TC) technology. Its framework and authentication flow are studied. The simulation result shows that peers have high anonymity degree and the model has good ability to withstand malicious peers’ behaviors.

摘要： 针对P2P系统中可信计算平台与传统的非可信计算平台所组成的异构系统间跨平台信任建立的问题，基于可信计算技术，提出一种全新的信任模型，对其架构和认证流程进行研究。仿真结果表明，系统中节点具有较高的匿名度，同时该模型具有良好的抵抗恶意节点行为的能力。
