GM/T 0003.2-2012 English PDF (GMT0003.2-2012)

This Part of GM/T 0003 specifies the digital signature algorithm of public key cryptographic algorithm SM2 based on elliptic curves, including the digital signature generation algorithm and verification algorithm and gives examples of digital signature and verification and the corresponding process. This Part applies to digital signatures and verification in commercial cryptographic applications, which can satisfy the security requirements for the identity certification and the integrity and authenticity of data in multiple cryptographic applications. Meanwhile, this Part can also provide standard positionings and standardization references of products and technologies for security product manufacturers to improve the credibility and interoperability of security products.
