Abstract:In advanced real-time database system, such as instrument interest, military defense, need for protecting information from unauthorized access has lead to more attention in the field of information security, since the system maintains sensitive information to be shared by multiple users. Access control mechanisms are powerful means to ensure information confidentiality and integrity. In this paper, real-time database and its character is briefly present firstly, then we examine access control mechanisms, finally access control is applied to real-time system to ensure security in real-time system.
Keywords:real-time database  access control  DAC  MAC  RBAC
