数据库加密方案及应用场景研究

扫码查看
实现数据存储加密有2种方案,密码机加密和数据库透明加密.其中,数据库透明加密又分为库加密、表加密、应用系统侧加密、网关透传加密以及数据库侧扩展加密.通过分析关系型数据库的不同加密方案及国产密码算法应用的实现,对不同加密方案的原理、优缺点和应用场景进行概括性的总结和对比.同时,总结涉及密文的索引、模糊查询、数值比较、聚合函数运算等数据库操作的实现方式.
Research on Database Encryption Scheme and Application Scenarios
There are two schemes to implement data storage encryption,cipher machine encryption and database transparent en-cryption,in which database transparent encryption is classified whole database file encryption,table encryption,application system side encryption,gateway through-pass encryption and database side extension encryption.By analyzing different en-cryption schemes for relational databases and the implementation of domestic cryptographic algorithm application,the princi-ples,advantages,disadvantages and application scenarios of different encryption schemes are briefly summarized and compared.At the same time,the implementation methods of database operations such as ciphertext index,ciphertex fuzzy query,cipher-tex numerical comparison and ciphertex aggregation function operation are summarized.
