摘要 从通用访问控制系统出发,提出以quorum系统来设计访问控制框架,给出了基于互斥协议的quorum分布式访问控制系统(MQ-DACS),以在保持高效率的情况下,提高访问控制决策的稳定性和安全性。进一步分析了在系统结点不可靠的环境中,系统能并行执行的访问控制容量同系统可用性之间的关系,并给出了最佳方案的选取依据。 By researching on generalized system for access control, the paper put forward an access control framework adopting quorum system, and presented a mutual quorum distributed access control system, with the high efficiency and the stability and security. Furthermore, the relation of system capability and system availability under the circumstance that the system nodes are not reliable was analyzed,and a result was given that the mode of the optimization of the entire system considers the capability and availability.
