摘要
研究如何在网格中建立基于行为的信任模型,排除内部恶意节点,提高系统的安全可靠程度。提出一种新型的基于行为的信任计算模型来处理网格环境中实体间的信任关系,该模型对域内信任关系和域间信任关系分别采取不同的方法进行处理,能够评估实体与实体间的信任关系,从而解决网格环境中存在的某些安全问题。
How to build trust model for grid computing in order to find out malicious users and improve security and reliability of system is studied.A new trust calculates model that is based on behavior is presented.This model is used to deal with trust relation with each entity in grid environment.The model takes different ways to deal with trust relation in and between regions,the model gets a more accurately way to evaluate the trust relation between entities.Thus,the model can solve the security problem in grid environment more effective.
