基于服务器-客户端的数据库系统的数据混合加密

Data Hybrid Encryption for Database System Based on C/S

数据库系统安全是构建信息管理系统的关键;在公钥密码系统的基础上,利用混沌映射产生的密码流对基于C/S结构的数据库数据进行加密,实现了每一个需要加密的记录对应一个密码的功能,极大地提高了数据库系统的可靠性;算法已实现,实践和理论分析表明,该算法具有很好的安全实用性。

Database security is a key to set up information management system. By means of public key cryptosystem, the chaotic cipher stream is used to encrypt the data of database based on C/S system. The method achieves the function that a record needed encrypting corresponds with a cipher, so that the encryption system can greatly enhance the security of database system. After analyzed with theories and practice, the algorithm is proved secure, quick and utilizable.
