OpenSSH 5.7 introduces support for Elliptic Curve Cryptography modes for key exchange (ECDH) and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer better performance than plain DH and DSA at the same equivalent symmetric key length, as well as much shorter keys.
scp has a new -3 option: Copies between two remote hosts are transferred through the local host. Without this option the data is copied directly between the two remote hosts.
ECDSA host keys are created during installation.
See OpenSSH 5.7 release notes for more information.
