**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 durance—that is I;

The eternal thing in man,

That heeds no call to die.”

—Thomas Hardy (1840–1928)
