实时数据库的访问控制

在现代实时数据库系统里面,如证券交易、国防军队系统,有大量敏感信息并且被不同用户共享,需要对他们进行安全保护,防止未经授权的访问。访问控制作为一种强有力的保护系统,能保证信息的完整性和机密性。该文先介绍了实时数据库及其特征,然后介绍访问控制机制,在此基础上,最后将访问控制策略应用到实时数据库,以保证实时数据库的安全。

Enforcing Access Control Mechanisms on Real-time Database System

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.
