Secure encryption method for database

Abstract

The invention discloses a secure encryption method for a database. In the method, encryption keys are not needed to be input through a user keyboard, the keys cannot be decoded through software and data transmission is safe. A secure encryption component (SCC) is arranged on a client and a server of the database, and comprises an identity authentication interface, a data block encryption interface, a data block abstract interface, a data stream connection authentication interface, a data stream encryption interface, a security policy combination module and a security instruction conversion module; after a database engine inputs data to be processed, the SCC calls the interfaces, the called interfaces formulate a security policy through the security policy combination module, combine the security policy into an application protocol data unit according to the security instruction conversion module, and transmit the application protocol data unit to high-speed mobile storage equipment; and the SCC gets back the result data and returns the result data to the database.

Description

Technical field [0001] The invention belongs to the technical field of computers, and specifically relates to a method for encrypting database files. Background technique [0002] Because the database system is managed in the form of files under the computer operating system, intruders can directly use the operating system vulnerabilities to steal database files, or directly use operating system tools to illegally forge and tamper with the contents of database files. This kind of hidden danger is difficult for general database users to detect, which requires the database management system to have a strong security mechanism. One of the effective ways to solve this problem is that the database management system encrypts the database files, so that even if the data is unfortunately leaked or lost, it is difficult to decipher and read. [0003] At present, mainstream large, medium and small databases have the function of encrypting data, but a common practice is that users specify an...

AI Technical Summary

Problems solved by technology

In order to ensure that the user can remember the key and hope to input it through the keyboard, they usually choose some meaningful character strings as the key, which will inevitably make the key easier to be leaked and stolen; at the same time, because the software algorithm is more common, After the intruder obtains the ciphertext and key, he can also use the software algorithm to decipher

[0004] Another security risk is that the security, integrity and non-tamperability of data cannot be guaranteed during transmission
