Encryption and decryption resource scheduling and key management-based encryption database and method

The invention discloses an encryption and decryption resource scheduling and secret key management-based encryption database and method, and mainly relates to a secret key management module and an encryption and decryption service module, the secret key management module is used for distributing and managing user information and secret keys thereof, and the encryption and decryption service moduleis used for encrypting SQL statements and solving the scheduling problem of the SQL statements. The invention provides a scheduling method. When multiple users and multiple threads simultaneously request encryption resources, distributing a priority number to an SQL statement requested to be encrypted; and then, sequentially allocating a time slice to the SQL statements according to the prioritynumber to occupy the encryption resources, and meanwhile, waiting for searching for an appropriate SQL statement in the SQL statements occupying the encryption resources according to the remaining encryption resources, and allocating the encryption resources to the SQL statements, so that the throughput of the encryption and decryption service module is improved. The key management module stores and manages user information and keys thereof in the form of key value pairs aiming at the problem that the same user has multiple keys, so that the difficulty of key storage and distribution is reduced.
