WebFeb 1, 2024 · In October 2010, China’s State Cryptography Administration issued the SM2 algorithm based on Public Key Elliptic Curve Cryptography. The SM2 algorithm is different from ECDSA, ECDH and other international standards in its digital signature and key agreement scheme, but it adopts a more secure mechanism. WebOct 1, 2024 · SM2 is China’s ECC algorithm defined over a special prime field, and it may be widely used to implement public key cryptosystems [10], [11]. The SM2 algorithm is still based on elliptic curves. Therefore modular multiplication is still the core operation in the encryption process.
