椭圆曲线密码学（ECC, Elliptic curve cryptography）是基于椭圆曲线数学的一种公钥密码的方法。椭圆曲线在密码学中的使用是在 1985年由Neal Koblitz和Victor Miller分别独立提出的。

-Elliptic curve cryptography (ECC of Elliptic curve to cryptography) is based on the mathematics of elliptic curves of a public key cryptography method. The use of elliptic curves in cryptography was proposed independently by Neal Koblitz and Victor Miller in 1985.
