Abstract

The invention provides an AES hardware implementation method based on reconfigurable computing, computer equipment operating the same and a readable storage medium operating the same. The hardware implementation method specifically comprises the following steps: 1, executing initialization; 2, calling a key operation unit; 3, reading and transmitting a data source; 4, calling an encryption / decryption calculation unit; 5, reading and transmitting result data; and 6, making a decision. The invention aims to improve the flexibility of an AES hardware implementation algorithm, reconstruct the hardware architecture according to different configuration information, and support the flexible configuration of an encryption and decryption mode of the AES encryption and decryption algorithm, a plaintext / ciphertext CBC / EBC grouping mode, and parameters such as a key length, an encryption and decryption round number, a total plaintext / ciphertext length and the like. According to the method, the configuration flexibility of AES hardware implementation can be effectively improved, meanwhile, three steps of row shifting, column confusion and byte substitution are combined, the key path of the AESalgorithm is reduced, and the hardware implementation speed is increased while the encryption and decryption precision is guaranteed.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an AES hardware implementation method based on reconfigurable computing, computer equipment and a readable storage medium for running the method. Background technique [0002] With the advent of the information age, the communication system is constantly changing. While information technology brings great convenience to people's economic and cultural production and life, people's demand for information security is also increasing day by day, and network security has become the focus of people's attention. Effective data encryption and decryption algorithms play a vital role in protecting information security. Modern encryption and decryption algorithms mainly include symmetric encryption algorithm (symmetrical encryption algorithm) and asymmetric encryption algorithm (asymmetrical encryption algorithm). Among them, the symmetric encryption algorithm adopts a single-key system,...
