分布式数据库安全的关键技术

The key technology of distributed database security

分布式数据库作为数据库系统与计算机网络的有机结合,成为目前互联网环境下信息资源的共享和应用核心,其安全问题举足轻重。该文针对分布式数据库系统的安全性要求,在分析了系统的体系结构和不安全因素的基础上,对安全策略和安全机制中身份验证、保密通信、访问控制、库文加密、密码体制及密钥管理、分布事务管理、审计跟踪、故障恢复等方面进行了综合分析。

A distributed database as database system and computer network organically, become the Internet under the environment of information resources sharing and application core, its important safety problems. According to the safety of distributed database system requirement, in the analysis of system structure and safety factor of the foundation, on the security policy and security mechanism of the identity authentication, communication security, access control, library, encryption, password system and key management, distribution affairs management, audit tracking, fault recovery, etc were analyses.
