Abstract:

Compared with traditional security authorized mechanisms, trust management is a more competitive, direct, efficient and sound distributed authorization, which can be adapted to grid applications development. This paper studies the key part of trust management system——trust models. Two behavior-based trust models: basic network behavior-based trust model and trust intermediary-based model are studied and analyzed. The paper analyses their advantages and weaknesses respectively. Some future outlook for grid trust models is offered.

摘要： 与传统的安全授权机制相比，信任管理是一种更具表达力，更直接、高效、完善的分布式授权方式，可以适应网格及其应用发展的安全需要。该文研究了信任管理系统中的关键部分――信任模型，对基于行为的网格信任模型，即基本网格行为信任模型和信任中介者模型进行了研究剖析，分析了其优点和不足，并对网格信任模型的未来进行了展望。
