摘要
针对普适计算环境下复杂的安全需求,设计了一个安全分布式访问控制系统。在系统体系结构设计中,提出了一个分布式授权查询算法,解决了普适访问控制系统授权查询的效率问题;引入授权模糊推理器,实现了普适访问控制的模糊推理授权。最后给出了一种加密机制,从而保证了系统在授权查询过程中信息的保密性和完整性。
This paper designed a secure distributed access control system for complex security requirements in ubiqui- tous computing environment and the system architecture was presented. A authorization query algorithm was proposed to solve the problem of the efficiency of authorization query. Fuzzy reasoning machine was proposed to achieve fuzzy au- thorization. Finally,an encryption mechanism was presented to ensure the confidentiality and integrity of information during the process of authorization query.
