在RT(一族基于角色的信任管理语言)的基本部分RT0的基础上提出了新的带有信任度的基于角色的信任管理模型(RTDOT),将信任度结合到信任管理中,并给出了模糊集合的语义。新模型体现了信任的主观性和模糊性,并可对委托深度进行控制,与模糊理论的结合为信任管理提供了一个新方向。
A novel Role-based Trust-management model with Degrees Of Trust (RTDOT) is proposed on the basis of RT0, the basis part of RT, wihich is a family of Role-based trust management Languages. Degrees of trust are combined with trust management, and a fuzzy set-theoretic semantics is proposed. This model embodies the subjectivity and the fuzziness of trust and can control delegation depths. A new direction is presented for trust management by combining with the fuzzy theory.
