Hardware implementation system for SM2 elliptic curve public key encryption algorithm under pixel field Fp

Abstract

The invention discloses a hardware implementation system for an SM2 elliptic curve public key encryption algorithm under a pixel field Fp. The system is reasonably divided into a plurality of modules under the pixel field Fp by adopting a high-level modularization method; message encryption and ciphertext decryption can be realized by using a hardware method; multiplexing of a random number generating module, an operation control module, a bit string processing module, a key derivation module and a hash module is realized by adopting a hardware module multiplexing method and setting upper-layer multiplexing modules; multiplexing of a point multiplication operation module, an XOR operation module, a bit string conversion module and a bit string splicing module is realized by setting lower-layer multiplexing modules; therefore, provided is a hardware implementation system for an SM2 elliptic curve public key encryption algorithm under a pixel field Fp, which is lower in hardware resource consumption, lower in cost, faster in operation, simple in structure and easy to implement.

Description

technical field [0001] The invention relates to message encryption and decryption technology in the field of information security, in particular to a hardware implementation system of SM2 elliptic curve public key encryption algorithm under prime field Fp. Background technique [0002] With the development of network technology, people pay more and more attention to network security issues. Information encryption and decryption technology is widely used in the field of network security, which can ensure the security of information and prevent information from being attacked during transmission, thereby being intercepted or destroyed by criminals. [0003] SM2 is an elliptic curve public key cryptographic algorithm released by the State Cryptography Administration on December 17, 2010. Compared with traditional public key cryptosystems (such as RSA cryptosystem), elliptic curve cryptosystems use relatively short keys to The same degree of security can be achieved. Therefore...

Problems solved by technology

[0004] Although the State Cryptography Administration announced the SM2 elliptic curve public key encryption algorithm as early as 2010, there are still relatively few schemes for implementing it in hardware, and the existing hardware implementation schemes consume a lot of hardware resources.
