网格安全中的信任度评估模型研究

The Study on the Trust Values Assess Model in Grid Computing Security

信任管理是当前网格计算安全研究的热点。在介绍网格基本概念、信任管理概念和概述信任度评估模型的基础上,根据信任评价的特点,提出了一个基于模糊理论信任度评估模型,描述了计算用户信任度的方法和步骤,使得信任度的计算更加灵活、评价更为合理科学。

Trust management is now one of the interesting research topics in the field of grid computing security. The paper introduces the basic concepts of grid computing, the basic theory of trust management and summaries the trust values assess system presented by others. And then, the model of trust values assess system based on fuzzy theory is presented, the method and computing steps of user＇ s trust values if described, which makes the computation of trust values more flexible and the access of trust values more scientific.
