WebbRFC 4492 ECC Cipher Suites for TLS May 2006 1.Introduction Elliptic Curve Cryptography (ECC) is emerging as an attractive public-key cryptosystem, in particular for mobile (i.e., wireless) environments. Compared to currently prevalent cryptosystems such as RSA, ECC offers equivalent security with smaller key sizes. This is illustrated in the following table, … WebbSM2 is based on ECC(Elliptic Curve Cryptography), and uses a special curve. It can be used in digital signature, key exchange and asymmetric cryptography. For key exchange, SM2 is similar to ECDH, but involves new random key, meaning the two sides need to exchange extra random public key besides their public key, that's why additional APIs are needed …
