| 摘 要： | 为了解决P2P网络的信誉问题，以电子商务为研究背景，设计了一种基于信任衰减向量的P2P网络信誉模型（P2P-Rep）。本模型采用混合结构式P2P网络的架构，对电子商务中各交易指标的评价向量进行衰减计算，基于交易评价因子推理计算直接信任度、间接信誉度和综合信誉度。仿真实验验证了该模型较低的资源开销和较高的交易成功率。

| Abstract: | In order to solve the reputation of P2P e-commerce,a reputation model P2P-Rep is proposed based on trust attenuation vector.It adopts hybrid P2P structure and damply calculated appraisal vectors which are based on each transaction factor.Using transaction appraisal factors,direct trust,indirect reputation and integrated reputation are calculated.Simulation results show this reputation model can cut down resource spending and increase the success rate of transaction. |
