1 Scope
This part of GM/T 0003 specifies the public key encryption algorithm for the public key cryptographic algorithm SM2 based on elliptic curves, and gives examples of message encryption and decryption and their corresponding processes.
This part is applicable to the message encryption and decryption in the commercial cypher application, the message sender can encrypt the message with the receiver’s public key and the receiver decrypts with corresponding private key to obtain the message. Meanwhile, this part also can provide standard setting and standardization reference with regard to products and technologies for security product manufacturers, and improve the credibility and interoperability of security products.
