摘要/Abstract

摘要： 传统基于信任域的网格信任模型以自治域内的实体数目作为信任值计算复杂度的唯一参数,安全性较低。在现有计算网格信任模型基础上,提出一种改进的自治域内实体信任模型,将时间衰减和惩罚因子引入到模型中,建立GSP对用户的直接信任度和推荐信任度计算模型,通过仿真实验验证其具有更高的抗Whitewashing攻击能力。

关键词: 计算网格,信任模型,UTA,GSP,Whitewashing攻击

Abstract: Traditional trust model of computing grid based on trusted domains has less secure,which uses the number of entity as the only parameter of trust value calculation complexity.The paper proposed an improved autonomous entity trust model based on existing model of computing grid,introduced the time decay and penalty factor and established a direct and recommendation trust model of GSP for user.The simulation results show that the proposed model has a higher defense capabiliy to Whitewashing attack.

Key words: Computing grid,Trust model,UTA,GSP,Whitewashing attack
