基于RBAC模型多级角色的SQLite3安全访问控制

摘要

SQLite3 is an embedded database but lack of complete secure access control mechanism. To solve this problem, this paper first designs a multi-level role function, then makes an analysis of the specific methods and steps of the access control mechanism for SQLite3 based on the RBAC model and combined with the source code of the SQLite3 database. Finally, it makes a detailed design and implementation of this access control mechanism for SQLite3. It is indicated by the experimental tests that the new secure access control mechanism not only succeeds the original advantages of SQLite3, but also improves the security of SQLite3.%针对嵌入式数据库SQLite3没有完整的安全访问控制的问题，本文基于RBAC模型，结合SQLite3数据库内核源码，设计了多级角色，分析了其访问控制的实现方法与步骤，详细设计并实现了 SQLite3的安全访问控制。实验测试结果表明该方法在继承SQLite3原有优点的同时，提高了SQLite3的安全访问控制能力。
