SM9 is a Chinese national cryptography standard for Identity Based Cryptography issued by the Chinese State Cryptographic Authority in March 2016.[1] It is represented by the Chinese National Cryptography Standard (Guomi), GM/T 0044-2016 SM9. The standard contains the following components:
- (GM/T 0044.1) The Identity-Based Asymmetric Cryptography Algorithm
- (GM/T 0044.2) The Identity-Based Digital Signature Algorithm which allows one entity to digitally sign a message which can be verified by another entity.
- (GM/T 0044.3) The Identity-Based Key Establishment and Key Wrapping
- (GM/T 0044.4) The Identity Based Public-Key Encryption Key Encapsulation Algorithm which allows one entity to securely send a symmetric key to another entity.
