> 中文摘要: 给出了描述行为驱动的信任管理语言RTB.将变量引入到角色中可以记录用户的累积行为状态;行为驱动的信任规则根据用户已发生的行为调整其在本信任域中被分配的角色;组合规则提高了信任判定的效率;信任策略更新规则允许信任域在系统状态发生变化时自动调整信任策略.描述了行为驱动的信任管理的实现框架,并讨论了优化实现的几种机制.
Abstract:RTB, the language describing behavior-driven trust management, is given. Variables are introduced into roles to maintain the cumulate behavior status of the users. Behavior-Driven credentials modify users’ assigned local roles in a trust domain according to the behaviors enforced by the users. Combined credentials improve the efficiency of trust determination. Trust policy update credentials allow trust domains to update trust policies automatically when the system statuses are changed. Implementation framework of behavior-driven trust management is described. Several optimization mechanisms of realization are discussed.
