摘要/Abstract

摘要： 针对EigenRep信任模型没有对节点恶意欺骗行为做出信誉惩罚修正的问题,改进了全局信誉的计算方法,即加入了影响因子,使得节点计算的全局信誉更客观。同时针对EigenRep模型每次交易都需要在全网络范围内做全局信誉的迭代计算从而导致系统开销过大的问题,提出了一种新的信任机制。实验表明,该机制结合风险、本地信任度和全局信誉的策略,可以大大减少系统开销,适合更大规模的网络环境的应用。最后,利用该机制实现了一个电子商务平台系统。

Abstract: The current EigenRep trust model could not make reputation punishment correction to the cheating behavior of malicious peers．To solve this problem,this paper improved the global reputation computing method．Many comprehensive factors in computing trust value are introduced in the mechanism．Moreover,another defect of EigenRep is that the system has to do the iterative calculation of global credibility within the whole network for each transaction,and this causes the system cost problem．To solve this problem,this paper presented a new trust mechanism which combines risk,local trustworthiness and global reputation．Simulations show that this mechanism could reduce the system cost greatly．At last,this paper realized an E-commerce platform system based on this trust mechanism.
