中文摘要：
提出了一种评价离散度敏感的P2P电子交易系统信任模型,该模型引入了基于推荐节点数量和推荐信息离散程度的全局声誉信度概念,以及直接声誉的相对信度概念,并给出了基于信度的信任度计算方法。通过仿真实验和分析,验证了该信任模型的有效性和抗恶意节点能力。与EigenRep进行比较,表明该文模型在抗恶意节点攻击能力上有了显著提高。
英文摘要：
For the openness,anonymity,and dynamic characters in P2P systems,participants lack trust relationship inference each other in P2P e-commerce communities.A rating dispersion sensitive trust model for P2P transactions is presented.The credibility of global reputation and direct reputation is introduced.The credibility of global reputation is calculated from the recommended peers’ number and recommended rating’s dispersion.The validity and anti-attack ability are proved by the simulation and analysis.The results of the experiments are compared with EigenRep and shows the sound performance of the model.
