WebAbstract. SM2 key exchange protocol is one part of the public key cryptographic algorithm SM2 which has been standardized by Chinese state cryptography administration for commercial applications. It became publicly available in 2010 and since then it was neither attacked nor proved to be secure. WebIn this paper, we proposed an efficient implementation scheme for digital signature based on the cryptography algorithm SM2, which is established as the Elliptic Curve Cryptography (ECC) standard of China. Algorithm analysis reveals speed bottleneck lies in scalar multiplication, which is time consuming for the master processor to implement.
