WebbThe SM2 signature algorithm is defined in [ ISO-SM2]. The SM2 signature algorithm is based on elliptic curves. The SM2 signature algorithm uses a fixed elliptic curve parameter set defined in [ GBT.32918.5-2024]. This curve is named "curveSM2" and has been assigned the value 41, as shown in Section 2. Webb18 feb. 2024 · The public key cryptographic algorithm SM2 is now widely used in electronic authentication systems, key management systems, and e-commercial applications …

Compared with RSA, the performance of SM2 is better and more secure. The password complexity is high, the processing speed is fast, and the computer performance consumption is comparatively small.
WebbIn this paper, we proposed an efficient implementation scheme for digital signature based on the cryptography algorithm SM2, which is established as the Elliptic Curve Cryptography (ECC) standard of China. Algorithm analysis reveals speed bottleneck lies in scalar multiplication, which is time consuming for the master processor to implement.
