【摘要】 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。更多还原

【Abstract】 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（ma-）（nagement）,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.更多还原
