摘　　要：数据本地复制主要涉及到数据的隐私和完整性,如果认证服务集成在数据本地复制里,则可以减少非法访问。因此提出了一个新的访问控制服务,称之为CCAC,这是专门针对于数据本地复制安全的。CCAC是基于染色体族和环境信息的机制,并且可以独立和分布部署,实验结果表明其性能较好。The replica location service （RLS） is most concerned with protecting the privacy and integrity of knowledge about the existence and location of data. An authorization service should be integrated with the RLS to avoid illegal accessing to the replica. In this paper, a novel access control service named CCAC is presented, which specializes in the security of RLS, based on Chromosome-Families and contextual information, which can deploy independently and distribute. The prototype of CCAC is designed and simulation results show its high performance.
