Data encryption and decryption processing system and method

Abstract

The invention provides a data encryption and decryption processing system and method. The system comprises a software processing program and a hardware processing device, wherein the software processing program comprises a user interaction module, a data processing module and an upper computer control module, the hardware processing device comprises a software and hardware interaction interface, amemory, a control register, a register configuration module, a data distribution module and a data encryption and decryption module, and the memory comprises an off-chip storage area, an on-chip instruction storage area and an on-chip data storage area. An encryption and decryption mode of cooperative work of software and hardware is adopted; Meanwhile, in the aspect of software, the data processing information is generated into a corresponding data processing instruction set, and in the aspect of hardware, an off-chip storage and on-chip storage two-stage storage structure is used, so that aparallel working mode of multiple encryption and decryption modes is realized, and the data encryption and decryption processing efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data encryption and decryption processing system and method. Background technique [0002] With the development of information technology, people's security awareness is gradually increasing, so people pay more and more attention to the protection of network data and personal information. Generally, the encryption mechanism of software encryption can be used to protect confidential data. Software encryption means that the user calls the information security module to encrypt the information before sending the information, and then after the user sends the information to the receiver, the receiver uses the corresponding decryption software to decrypt and restore it. [0003] At present, when data is encrypted and decrypted, encryption and decryption software is usually used to encrypt and decrypt data. [0004] When the data is encrypted and decrypted by the encryption...

AI Technical Summary

Problems solved by technology

[0004] When encrypting and decrypting data through encryption and decryption software, the data encryption and decryption process is completed on the CPU. When the amount of business data is large, the method of encrypting and decrypting data through encryption and decryption software will cause a heavy burden on the CPU. Large, the CPU needs a long time to complete the encryption and decryption of data, which in turn results in low efficiency of data encryption and decryption
