Rule-based automated trust negotiation model
一种基于规则的自动信任协商模型

In the Automated Trust Negotiation (ATN), access control policy regulates user's access to resource so as to protect sensitive information and resource. However, access control policy itself may contain sensitive information; its disclosure may result in privacy leakage. And policy's increases enhances the negotiation complexity. In order to handle such a dilemma, a rule-based ATN model, called Rule-Based Automated trust negotiation Model (RBAM), was proposed. RBAM treats all policies as rules, divides them into two parties, and introduces Agent to implement rules, which can reduce the complexity and improve negotiation efficiency.
