Abstract: SM2 digital signature algorithm is an important part of Chinese commercial cryptography system, which has been widely used in electronic signature and other fields. Studying the potential security vulnerabilities of SM2 digital signature algorithm and the corresponding prevention methods are of great significance to promote the application of Chinese commercial cryptosystem. The security of SM2 digital signature algorithm is based on the hardness of elliptic curve based discrete logarithm proble... More
