| 摘 要： | 自动信任协商是陌生实体之间通过请求和披露信任进而逐步建立信任关系的重复过程，其中资源的拥有敏感保护已经引起了广泛的关注。该文给出关联属性的形式化定义，提出关联属性保护策略的层次契约模型，基于以上理论，通过在策略库系统中设置一个契约中间件达到信息拥有敏感保护的目的。

| Abstract: | Automated trust negotiation is an iterative process that establishes trust gradually between strangers by requesting and disclosing digital credentials. Protection of sensitive information in automated trust negotiation has been drawn much attention. In order to solve this problem, formal definition of relevant attributes is given. Relation model of relevant attributes is designed. A desideratum of policy for relevant attributes based on the relation model is presented. And the desideratum is enforced in a relevance contractor, which is an addition to the policy database system as improvement. The relevance contractor is used to check whether the policies satisfy the desideratum. |
