Data encryption and decryption method and system, and computer readable storage medium

Abstract

The invention discloses a data encryption and decryption method. The method comprises the steps that a CPU determines a type of a received to-be-processed data set; the to-be-processed data set is sent to a FPGA according to the type of the to-be-processed data set; if the to-be-processed data set is an encrypted data set, the FPGA decrypts the encrypted data set so as to obtain processed data; ifthe to-be-processed data set is an decrypted data set, the FPGA encrypts the decrypted data set so as to obtain processed data; and the CPU reads the processed data. According to the method, the FPGAencrypts and decrypts the data, thereby improving data processing efficiency and shortening the product development cycle. The invention further discloses a data encryption and decryption method andsystem and a computer readable storage medium that have the same beneficial effects.

Description

Technical field [0001] The present invention relates to the technical field of reconfigurable computing, in particular to a method for realizing data encryption and decryption, and also to a system and computer readable storage medium for realizing data encryption and decryption. Background technique [0002] Due to the rapid increase in the amount of data in the information age, the privacy and security of information and data have become the most valuable assets in various business fields. All commercial companies will implement strict information protection for the data in their fields from system access to data reading. Data encryption is an effective means to protect information, which can prevent unauthorized users from reading and disseminating it. [0003] Symmetric encryption algorithm is an encryption algorithm that has been applied earlier and has more mature technology. In symmetric encryption algorithm, the data sender processes the plaintext (original data) and encry...
