Background:

Elliptic curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. One of the main benefits in comparison with non-ECC cryptography [..] is the same level of security provided by keys of smaller size. ECC on Wikipedia, 2015-11-05
