摘　　要：随着P2P网络、Ad hoc、无线传感器网络的深入研究,信任和信誉成为保障这类自治网络安全的一个重要手段。虽然信任信誉系统在自治网络中起到了重要的作用,但其采用了间接推荐等技术,给信任信誉带来很多安全问题。介绍了信任信誉模型的相关概念,总结了目前对信任信誉模型的新攻击手段,并针对这些攻击,比较分析了在自治网络环境中具备一定防御能力的典型信任信誉模型的各自防御方法、防御效果以及性能情况。最后,在分析了现有研究存在的主要问题的基础上,展望了今后提高信任信誉模型安全性研究的主要方向。With the in-depth research of peer-to-peer networks, Ad hoc networks, wireless networks etc, trust and reputation become important means to the protection of Autonomous Networks. Although the trust and reputation managements have played an important role, indirect recommendation techniques bring a lot of security issues in the trust and reputation systems. After the concepts of trust and reputation were presented, some novel attacks related were given. And then several typical trust/reputation models with defense capabilities for the self-government networks were ana- lyzed and compared in security and performance after they were described briefly. Finally, the current problems and also challenges in the future in security of trust and reputation model were presented.
