摘要
Abstract
Data security is a big block for the promotion of cloud computing, which is mainly derived from data sharing and privileges of vendors. This paper analyzes features of data storage and user groups in cloud computing, proposes a kind of cloud computing access control based on Tasfc-role-based Access Control(T-RBAC) model, which provides different access control poiicy for different object to achieve ftierarchicai safety. And vendors enjoy no privileges in this mode. Analysis indicates that this cloud computing access control model provides more reliable security feature which can no longer rely on credibility of server.关键词
