Elliptic Curve Diffie–Hellman
Elliptic curve Diffie–Hellman (ECDH) is an anonymous key agreement protocol that allows two parties, each having an elliptic curve public-private key pair, to establish a shared secret over an insecure channel. This shared secret may be directly used as a key, or better yet, to derive another key which can then be used to encrypt subsequent communications using a symmetric key cipher. It is a variant of the Diffie–Hellman protocol using elliptic curve cryptography.

Famous quotes containing the word curve:
“The years-heired feature that can
In curve and voice and eye
Despise the human span
Of durancethat is I;
The eternal thing in man,
That heeds no call to die.”
—Thomas Hardy (18401928)
