GB/T 32918.4-2016: Translated English of Chinese Standard. (GBT 32918.4-2016, GB/T32918.4-2016, GBT32918.4-2016): Information security technology - Public key cryptographic algorithm SM2 based on elliptic curves - Part 4: Public key encryption algorithmThis Part of GB/T 32918 specifies public key encryption algorithm of public key cryptographic algorithm SM2 based on elliptic curves. It gives the message encryption and decryption examples as well as the corresponding process. This Part applies to message encryption and decryption in commercial password applications. The sender of the message can encrypt the message with the receiver public key. The receiver decrypts with the corresponding private key to obtain the message. |
