摘要:
 为了动态提升P2P网络的适应性、可靠性和可信度，在DyTrust信任模型的基础上，考虑到风险因素和时间因素对P2 P网络节点信任的影响，引入一个基于服务质量的风险函数和时间衰减因子棕，提出一种适合P2 P复杂环境的信任模型。实验结果表明，相比现有信任模型，文中研究的P2 P网络信任模型具有更好的动态自适应能力、更强的恶意节点检测能力，以及更优越的反馈信息聚合能力，对P2 P网络的安全提供有力保障。
Abstract:
 In order to dynamically improve the adaptability,validity and reliability of P2P Network,based on DyTrust trust model,consid-ering the influence of risks and time on the trust of P2P network node,a risk function and a reduction time factorωis introduced based on service quality,propose a trust model adapted to P2P network. The simulation experiment proves that compared with current model,P2P network trust model can provide safeguard with P2P network safety because it has better dynamic self-adaptability,better ability to check the malicious peers,and better advantage to aggregate feedback information.
