摘　　要：在数据库使用过程中存在一类特殊的安全性问题,即合法用户通过访问数据库系统获得一些重要敏感数据,在数据的使用过程中造成泄密事故,或者恶意修改一些数据以达到非法目的。数据管理方希望能够以一种可信方式证明追踪合法用户对特定数据的访问顺序及操作类型,用于辅助划定或区分事故责任,为实现该目标设计出一种基于安全散列加密算法的数据库操作痕迹可证明追踪算法。该算法显著区别于系统安全日志的可全程演进数据访问行为而证明力弱的特点,它引入安全散列加密算法,对操作行为以加密形式全程记录操作过程,为后期辅助判定事故责任提供强有力的技术支持。In the process of database use,there is a special security problem,legitimate users through access to the database system to obtain some important sensitive data,in the process of data use caused by leaks,or malicious modification of some data to achieve illegal purposes.In order to achieve this goal,a database operation trace provable tracking algorithm based on secure hash encryption algorithm is designed to prove and trace the access order and operation type of the specific data of the legitimate users in a credible way.The algorithm is significantly different from the characteristics of the system security log,which can be fully evolved data access behavior and has weak proof power.It introduces the security hash encryption algorithm,which records the operation pro⁃cess in the form of encryption,and provides strong technical support for the later auxiliary determination of accident responsibility.
