Sm2 point not on curve

WebbUnder this circumstances, the SM2, a set of public key cryptographic algorithms based on elliptic curves published by Chinese Commercial Cryptography Administration Office, was standardized at ISO in 2024 to enhance the cyber-security. However, few research works on the implementation of SM2 for constrained devices have been conducted. 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.
