Elliptic curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. The use of elliptic curves in cryptography was suggested independently by Neal Koblitzand Victor S. Miller in 1985.
Elliptic curves are also used in several integer factorization algorithms that have applications in cryptography
