摘要
根据大规模、开放式的分布式网络环境的特点,分析了传统安全机制的不足,把信任机制引入到访问控制中,并给出了信任的定义和分类,重点讨论了行为信任的性质和计算方法,给出相应的访问控制模型。通过同时对身份信任和行为信任的验证,增强了资源访问的安全性。
According to the characteristics of the large-scale distributed network environment, the flaws of trade security mechanism is analyzed and trust is introduced in access control mechanism. The definition and classification of trust are given, the properties and calculation method of behavior trust is discussed, and the corresponding access control model is given. Identity trust and behavior trust are both verified to enhance the resources of the security.
