Embodiment

[0042] The user logs into the application system and stores the data to be encrypted in the encrypted database. The application system conducts identity verification through the secure database access interface and the database encryption service system, and the verification passes. Then, the encryption function in the database encryption extension component calls the encryption device in the database encryption server to encrypt ordinary data, and the secure database access interface encrypts large data objects. Finally, the encrypted data is stored in the encrypted database through the database management system.

[0043] Users log in to the application system and query data from the encrypted database. The application system conducts identity verification through the secure database access interface and the database encryption service system, and the verification passes. Then, the decryption function in the database encryption extension component calls the cryptographic d...

Abstract

The invention provides a database security system based on storage encryption, comprising a database encryption server, a database encryption expansion component, a safe database access interface anda management tool. A database encryption service system encrypts and decrypts all data in the database security system and intensively applies safety control and management; the database encryption expansion component connects with the database encryption service system and a database management system and calls a cipher service function of the database safety service system to encrypt and decryptroutine data; the safe database access interface provides safe and transparent database access support to an application system; the management tool is used for safety configuration management by management personnel. The database security system provides an interface standard conforming to database access, supports transparent encryption and decryption of routine data and big data object, and screens complex details realizing the security function of the database for the application system.

Description

technical field [0001] The invention belongs to the field of computer information security, in particular to a database security and secrecy system. Background technique [0002] Information security is one of the important factors affecting the process of informatization. In recent years, the industry has gained a deep understanding of the importance of information security, and has adopted a large number of active and effective measures, but they all focus on the protection of the network and operating system, and not many directly protect the information in the database. In fact, the database is a warehouse for storing information, and its security is the core of information security, and it is also the last line of defense for information security. The commercialized database management systems commonly used at present generally cannot meet the needs of systems with relatively high security levels in terms of user identity verification and authority control. Therefore, ...
