High-speed encryption and decryption device composed of encryption and decryption module array

Abstract

The invention discloses a high-speed encryption and decryption device composed of an encryption and decryption module array. The device comprises a communication interface, an encryption and decryption array management module used for managing resource allocation and states of all encryption and decryption units in the encryption and decryption module array, a master controller and the encryption and decryption module array, wherein the master controller is used for sending an encryption and decryption instruction to corresponding channel control units according to the running states of all the encryption and decryption units and identity information carried in an input encryption and decryption instruction, outputting data subjected to encryption and decryption from the corresponding encryption and decryption units according to identity information carried in an output instruction and returning the data to a computer host; and the encryption and decryption module array comprises multiple groups of encryption and decryption modules, and each group of encryption and decryption modules comprises one channel control unit and the encryption and decryption units connected with the channel control unit in a one-to-one correspondence mode through a bus protocol interface. Through the device, the operation scale of parallel encryption and decryption is enlarged, encryption and decryption efficiency is improved, and arrangement cost is lower by the adoption of an array mode.

Description

technical field [0001] The invention relates to the field of hardware encryption, in particular to a high-speed encryption and decryption device composed of an array of encryption and decryption modules. Background technique [0002] In today's society, the data security requirements of computer equipment are getting higher and higher, and the performance requirements for encryption and decryption are also getting higher and higher. Computers using software encryption will increase the operating load, and it is easy to be cracked by hackers, so hardware encryption equipment is required. [0003] However, at present, the encryption components of the domestic hardware encryption equipment are relatively scattered, which leads to the small operation scale and high cost of the encryption equipment as a whole, which in turn leads to insufficient performance, low processing efficiency, and slow processing speed. [0004] Therefore, how to provide an encryption and decryption devi...
