摘要
以关系数据库为数据模型,在分析数种已有的数据加密技术基础上,研究数据库数据以密文方式存储并建立相应的数据库验证机制,立足于解决数据库中最为关键的数据库验证机制等方面的理论、方法和技术问题;提出基于连接的子密钥生成算法以及基于用户信息的密钥管理技术和字段的记录验证技术,保证数据库的安全;有效地管理生成子密钥的字段加密技术所需的密钥,适应于客户端或服务器的加解密,适应于字段验证技术的灵活性和记录验证技术的安全性。
Taking the relational database as the data model, based on analyzing several kinds already in the data encryption technology which has, studies the database data to save and to establish the corresponding database confirmation mechanism by the scrambled text way. Based on the database, solve the most critical database authentication mechanisms such as the theories, methods and technical issues. Proposes based on the connection sub - key production algorithm as well as based on the user information key management technology and the field record confirmation technology, guarantees the database the security. Effective management of the generation of key fields for key encryption technology, adapted to the client or the server encryption, authentication technology adapted to the flexibility of field records and verify the security of technology.
