嵌入式数据库SQLite的安全机制分析与设计

针对开源的嵌入式数据库SQLite存在的安全问题，在分析常用的数据库安全机制的基础上，为其设计了一套可行的安全机制。将口令认证与数据加密结合，通过增加密钥创建、数据加解密、页面编码以及事件记录等代码，实现了更安全的SQLite数据库。测试结果表明：该系统在继承其嵌入式数据库特点的同时，安全性得到提高。

Analysis and Design of the Security Mechanisms of Embedded Database SQLite

This paper is to solve the security problems of open source database SQLite. It first analyzes some security methods commonly used in Databases and then designs a set of feasible mechanisms for SQLite. Finally, it combines password authentication and data encryption, realizes a more secure SQLite by adding some codes of key deriving, data encryption, page coding and fault logging. It is indicated by testing that the modified SQLite is more secure than the original one.
