Abstract
AKE with derived ephemeral keys is described. In one aspect, a first party computes a derived ephemeral public-key based on a derived ephemeral secret key and a mathematical group. The derived ephemeral secret key is based on an ephemeral secret key and a long-term secret key. The first party generates a session key for secure exchange of information with a second party. The session key is generated using the derived ephemeral secret key and a second party derived ephemeral public-key key to demonstrate to the second party that the first party possesses the long-term secret key.
