Abstract
A key agreement protocol for use in a public key cryptographic scheme between a pair of correspondents each of which has a long term public key and an ephemeral public key. The protocol includes the steps of exchanging the ephemeral public keys between the correspondents for computing a shared secret at each correspondent and utilizing the shared secret to obtain a common key, wherein the validity of the ephemeral public keys is checked by the recipient thereof prior to use of the common key.
