基于免疫体系的安全数据库结构设计研究

提出了基于免疫体系的安全数据库四层结构：身份认证层，存取控制层，约束安全层，适应性检测层。并给出了约束安全层和适应性检测层的予层结构。将约束安全层分为完整性约束、分级和推理约束、访问约束和应用语义约束四个予层，将适应性检测层分为数据库活动级、关系模式级、事务级和应用语义级四个子层。构造了一个多层多级的数据库安全体系，最后给出了具体实现方案。

Research on System Architecture of Secure Database Based on Immune Architecture

This paper presents a secure database based on immune architecture. The architecture has four tiers in- cluding identification and authentication layer, access control layer,constraints security layer and adaptive detection layer. The paper also discusses the structures of the sub layers of the constraints security layer and the adaptive de- tection layer. The constraints security layer consists of integrity constraints,classification and inference constraints, access constraints,and application semantics constraints. The adaptive detection layer consists of active database lev- el,relation schema level,transaction level and application semantics level. The paper outlines a multilayer and multi- level database security architecture. At the end of the paper,a detailed implementation is demonstrated.
