"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 at Wikipedia, 2015-11-05

GnuPG supports ECC since version 2.1 and creates ECC keypairs by default since version 2.3.
