基于Logic SQL的B1级安全数据库的设计与实现

THE RESEARCH AND DESIGN OF B1 SECURE DATABASE BASED ON LOGIC SQL

基于对B1级安全数据库的研究与分析,介绍了2个数据库安全模型:Bell-La Padu la模型、基于角色的访问控制模型(RBAC);结合LogicSQL数据库的研究,设计了其B1级安全模型。主要从LogicSQL的用户身份认证、自主访问控制、基于角色的访问控制、强制访问控制、安全标签和审计等几个方面进行了讨论。

Based on researching and analyzing of B1 Secure Database, this paper introduced Bell-La Padula and Role-Based Access Control of database security model. The paper designed B1 security model for Logic SQL database. We discussed some aspects of Logic SQL security model, including User Identifier, Discretionary Access Control, RoleBased Access Control, Mandatory Access Control, Logic SQL Label, and Audit.
