Problems solved by technology

[0003] Take the SQL server database as an example. This database has its own encryption and decryption functions, but its encryption method is too complicated, and the efficiency of the decryption function is not high. It takes a long time to process large-scale data queries, which will cause information The system efficiency becomes low, and even freezes and other situations occur

Abstract

The present invention belongs to the technical field related to information security, and discloses a bottom data encryption method applicable to enterprise management information systems. (2) create a trigger in the table that needs to be encrypted, and the trigger will encrypt the unencrypted data and cover the original data; (3) use the decryption function to make the enterprise management information system required views and stored procedures, and then encrypt the views and stored procedures; (4) build function modules and report modules, and call corresponding functions according to the requirements of the function modules and the report modules The view and the stored procedure; at the same time, setting permissions for the function module and the report module. The invention improves efficiency and realizes fast decryption and display of data.

Description

technical field [0001] The invention belongs to the technical field related to information security, and more specifically relates to a bottom data encryption method suitable for an enterprise management information system. Background technique [0002] During the development, operation and maintenance of ERP management information systems, development and operation personnel will come into contact with a lot of enterprise data. Most of the data is not classified or sensitive, but there is still a small amount of sensitive data. Some sensitive data needs to be kept private, such as employee salary data. Employees' salaries are not allowed to be viewed by other employees at will. However, in the actual process, these salary data are stored in plain text at the bottom layer, and can be viewed by operation and maintenance personnel with database super administrator privileges. How to make the operation and maintenance personnel with database super administrator privileges una...
