分布式信任模型直接信任的模糊计算方法

在电子商务、数据通信和网络安全等应用系统中，信任模型是不可缺少的基本机制。但是对于Ad—hoe网络，Peer-to—Peer网络等分布式系统，由于不存在集中专用的服务器，传统的信任模型无法被采用。本文分析了保证分布式信任模型有效性的关键因素，提出了一种新的直接信任模糊计算方法，仿真数据表明，新方法比传统方法更准确。

FUZZY METHOD FOR DIRECT TRUST IN DISTRIBUTED TRUST MODEL

Trust model is one of the key mechanism in the e-business?data communication and network security system.Traditional trust model is invalid in some new distributed system,such as Ad-hoc network and Peer-to-Peer network.In this paper,we figure out the key element for distributed trust model's validity and introduce a new fuzzy method for direct trust.At last,the simulation results prove our new method's advantages.
