The invention discloses a computer data encryption apparatus for a virtual storage disk. The apparatus comprises a storage protocol interface, a data cache, a storage space management module, a main controller, a plurality of channel management modules and a plurality of encryption and decryption units, wherein the storage space management module is used for detecting running states of the encryption and decryption units and feeding back the running states to the main controller; the main controller is used for controlling the data cache to send a writing encryption and decryption instruction to the corresponding channel management module according to the running state of each encryption and decryption unit and an encryption and decryption operation storage address carried by the writing encryption and decryption instruction, reading encrypted and decrypted data from the corresponding encryption and decryption unit according to an encryption and decryption operation storage address carried by a reading instruction, and returning the data to a computer host; and the channel management modules are arranged in one-to-one correspondence with the encryption and decryption units and used for sending the received writing encryption and decryption instruction to a corresponding address space in the corresponding encryption and decryption unit. According to the apparatus, parallel encryption and decryption can be realized, so that the encryption and decryption efficiency is high. The invention furthermore discloses a computer data encryption method for the virtual storage disk.
Description
technical field [0001] The invention relates to the field of hardware encryption, in particular to a computer data encryption device and method for a virtual storage disk. Background technique [0002] In today's society, the data security requirements of computer equipment are getting higher and higher. The software encryption method used by the computer will increase the operating load, and it is easy to be cracked by hackers, so the current multi-hardware encryption method. [0003] Hardware encryption uses an external hardware-specific encryption device for encryption. The encrypted or decrypted data is input into the encryption module for encryption or decryption. After the encryption or decryption is completed, the data is returned to the user or sent to the back-end hard disk for storage. [0004] However, the current hardware encryption method uses serial processing, which has low processing efficiency and takes a long time. [0005] Therefore, how to provide a com...
