The invention discloses a virtual machine encryption method, a decryption method and an encryption-decryption control system. The virtual machine encryption method comprises the following steps: a user applies for creation of an encrypted virtual machine disk file through a client, and performs a user identity authentication process; after authentication, a virtual machine management sub-system allocates virtual machine resources to the user, and a strategy execution module creates a new virtual machine disk file; the strategy execution module performs identity authentication on a key and the strategy management sub-system, and receives the symmetric encryption key of the virtual machine disk file after the authentication succeeds; the strategy execution module transmits the symmetric encryption key to a file encryption-decryption engine to encrypt the virtual machine disk file; the file encryption-decryption engine submits the encrypted virtual machine disk file to the strategy execution module for storage; the strategy execution module synchronizes the key and an access strategy with the key and strategy management sub-system. By adopting the virtual machine encryption method, the decryption method and the encryption-decryption control system, safe and transparent data encryption and decryption are provided for the user to use a virtual machine, and a complete identity authentication mechanism is provided to ensure the user access security of the virtual machine.

The invention provides a secret key management method and a device for encrypting a data base column. The secret key management method includes using three-stage secret keys to encrypt data and store the data, wherein first-stage secret keys are main key pairs, second-stage secret keys are table secret keys, and third-stage secret keys are work secret keys. The secret key management device comprises an encrypting and decrypting module, a secret key dictionary and an interactive dictionary and is used for encrypting and decrypting the data. According to the secret key management method and the device for encrypting the data base column, system resource consumption brought by the storage of a large amount of work secret keys is reduced, and the risk of information revealing caused by static storage of secret keys is reduced, so that the efficiency and safety of secret key management are optimized and improved; and the problems existing in secret key management of the encryption of the data base column are solved. The secret key management method and the device for encrypting the data base column have the advantages that the three-stage secret keys are used so that the safety of the data base is enhanced; a small amount of the table secret keys are used for managing a large amount of the work secret keys; and the work secret keys are dynamically generated and are not required to be stored, so that storage space is saved.
