分布式数据库系统安全策略分析

Analysis of Security Strategy on DDBS

分布式数据库作为数据库系统与计算机网络的有机结合，正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。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可能受到的攻击的基础上，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。

As the combination of computer network and database system Distributed Database is becoming the share center of information resource in the Internet situation and its security is very important. Aiming at the secure requests of Distributed Database System, on the base of analysing system frame and possible attacking. It discusses user authentication, secret communication, access control, content ciphertext, cryptosystem, key and distributed affair management, audit track, fault repair in the security police and security mechanism.
