The invention discloses a field programmable gate array (FPGA)-based advanced encryption standard (AES) encryption and decryption network communication device and an implementation method thereof. The device comprises a micro control unit (MCU) and an AES encryption and decryption unit. The method comprises the following steps that: the MCU receives a network data packet from a network port, controls the grouping of the received network data packet, and forwards a network data group; and the AES encryption and decryption unit inserts a data tag for recording an address and the number of rounds into the network data group, performs intra-round routing control on the network data group according to the inserted data tag, performs AES encryption and decryption on the network data group in parallel, and outputs the AES-encrypted and decrypted network data packet. The device and the method have the high-speed hardware parallel processing advantage of an FPGA and the high communication and intelligent control capabilities of the MCU, so that effective working efficiency is greatly improved, and high communication and intelligent control capabilities are ensured. The FPGA-based AES encryption and decryption network communication device and the implementation method thereof are widely applied to the field of network communication.
Description
technical field [0001] The invention relates to Internet network communication technology and electronic circuit technology, in particular to an FPGA-based AES encryption and decryption network communication device and its implementation method. Background technique [0002] Today's data is easily stolen by others during network transmission, so network data transmission has a great security risk. In order to solve this problem, data transmitted on the network should be encrypted. In the field of encryption technology, the most widely used encryption algorithm is the national standard DES algorithm promulgated by the United States in 1977, but compared with the traditional DES algorithm or 3DES algorithm, the AES algorithm has obvious advantages in terms of speed and security . In addition, nowadays, software programs are usually used to encrypt data, but the time delay is large and the processing speed is slow. Contents of the invention [0003] In order to solve the ab...
