Abstract： Applying elliptic curves on public key cryptosystem was put forward independently by Koblitz and V.Miller in 1985. Public Key Cryptographic Algorithm SM2 is Public Key Cryptographic Algorithm SM2， as the Chinese national cryptographic standard， is widely used in communications of automation system. This paper introduces elliptic curve cryptosystem and gives an implementation based on C language.
