【摘要】 由于传统的集中式信任机制不适合P2P网络,提出了一种应用于P2P网络的分布式信任模型。它根据交易历史信息来计算节点的全局可信度。此模型运算量小,没有迭代运算不收敛的问题,并能较好地处理冒名和诋毁等非法行为,具有较强的安全性。计算机仿真亦证明了此模型的良好性能。更多还原

【Abstract】 As the traditional concentrated trust method could not be used in peer-to-peer networks,a distributed peer-to-peer trust model was proposed.A peer’s trust value was calculated according to the historical transaction information of the peer in this model.This model used an easy method to calculate the trust and avoided the divergence of iteration for trust calculation.In addition,this model could deal with some security problems,such as impostor attack and slander.The computer simulation results testify these merits.更多还原
