An SM2 algorithm, such as encryption, decryption, signature, signature verification, key agreement, key generation and the like based on SM2, is realized by adopting a message protection system, SM2 protocol correlation is realized by control of a processor, and calling of a true random number generator, an underlying cryptographic algorithm and elliptic curve operation is also realized by control of the processor. Meanwhile, the SM3 hash algorithm, the key derivation function, the point multiplication operation, the point addition operation, the point doubling operation and other operations of the SM2 algorithm are all realized by the FPGA logic, the parallel computing capability of the FPGA is utilized, the operation efficiency is improved, and the operation time is greatly shortened.

Description

technical field [0001] The present application relates to the technical field of network security, in particular, to a message protection system and a message protection method. Background technique [0002] The SM2 algorithm is based on elliptic curve calculations. Calculation efficiency is one of the most concerned issues in elliptic curve cryptography. Point operations (point addition, point doubling, and point multiplication) on elliptic curves account for most of the calculations. For a dedicated cryptographic algorithm chip that is required for a single SM2 algorithm, the chip development cycle is long, lagging behind the development of technology, and easily causing waste of resources, and the performance improvement for SM2 is also relatively limited. [0003] At present, the SM2 algorithm is widely used in fields such as encryption, decryption, signature, signature verification, key negotiation, and key generation. Good at big data point calculation, low calculatio...
