Library table data encryption storage method based on SQL reconstruction

Abstract

The invention discloses a database table data encryption storage method based on SQL reconstruction, and relates to the technical field of database security. The method comprises the following steps: intercepting access to a database, acquiring a corresponding SQL statement and transmitted parameters carried by the SQL statement, encrypting the transmitted parameters according to transmitted parameter information, reconstructing the SQL statement, writing the reconstructed SQL statement and the encrypted transmitted parameters into the database, configuring an encrypted information buffer pool, acquiring corresponding encrypted information in the encrypted information buffer pool according to the transmitted parameter information, encrypting the transmitted parameter according to the corresponding encryption information, intercepting data returned by the database, and decrypting and displaying the data.

Description

technical field [0001] The invention discloses a method and relates to the technical field of database security, in particular to a database table data encryption storage method based on SQL reconstruction. Background technique [0002] At present, the database encryption technology is relatively mature, but most of them are realized by using physical encryption machines. However, the existing physical machine encryption methods cannot meet the needs of current multi-application scenarios, and the reliability and security of data storage need to be further improved. At the same time, physical machine encryption Encryption procurement costs are high, and the dependence is too strong, which is not conducive to operation and maintenance and implementation delivery. Moreover, there are many physical encryption machine providers, which require frequent docking, which is not conducive to system decoupling. Contents of the invention [0003] Aiming at the problems of the prior ar...
