Abstract
Based on the analysis of various access control mechanisms, a widely applicable privacy-preserving and security hybrid access control mechanism for systems is proposed. This mechanism, which is called attribute and role based hybrid access control mechanism of encryption and time (ET-ARBHAC), consists of two processes, namely the attribute-based access control (ABAC) process and role-based access control (RBAC) process. In ET-ARBHAC, ABAC procedure is designed to encrypt related attribute values and allocate roles and RBAC procedure is added a re-verified time mechanism to increase system security and save system resources. Theoretical methods and architecture of the mechanism were illustrated in this paper. This study provides precious theoretical contributions for researchers and theoretical references for system/website developers, system operators and system technology vendors.
