摘　　要：自动信任协商是一种在开放网络环境下陌生实体之间通过披露属性证书建立双方信任关系的重要手段。针对传统信任协商中协商规则描述较为严格、协商成功率和效率较低的问题,提出了一种基于模糊逻辑的自动信任协商方案,它通过将模糊逻辑引入信任协商,对信任协商规则进行模糊化处理,可以更简单而灵活地描述协商规则,并由此优化协商路径选择。分析表明,这种协商方案能够在一定程度上提高协商成功率和效率。Automated trust negotiation （ATN） is an important method for establishing the trust between strangers in open network environment by disclosing attribute certificates. Because it is difficult to use tranditionat trust negotiation to describe the credential access control policies and establishing the trust is inefficient, a fuzzy logic-based scheme was proposed. By modeling the credential access control policies in fuzzy logic formula, the description will be more concise and flexible,and negotiation path will be optimized. The analysis shows that efficiency and success rate of this negotiation scheme can be improved to some extent.
