摘　　要：普适计算是国际公认的未来计算主流模式之一,本文针对其安全性问题,提出了普适环境下的基于信任度的动态模糊访问控制模型TDFACM,该模型将传统的访问控制模型与区间值模糊计算理论结合,通过对主体信任度评估进行授权决策,并给出了加权模糊值推理方法.该模型能更好的解决普适环境下访问控制模型的实用性与安全性.Pervasive computing is considered as one of internationally recognized mainstreams of future computing. Trust-based Dynamic fuzzy access control model TDFACM in pervasive computing was put forward according to its security problem. This model combined traditional access control model with the theory of interval-vlaued fuzzy computing. Authorized decision will be made in accordance to the trust evaluation to the subject and the way of authorized fuzzy interference will be given as well. This mode can well solve the security and practicability of access control model in pervasive computing.
