Abstract:
1. A computer-implemented method for key confirmed (KC) authenticated key exchange (AKE) with derived ephemeral keys protocol using a mathematical group, the method comprising: generating, by a first party being a computing system configured for KC-AKE with derived ephemeral keys protocol using a mathematical group, a first-party derived ephemeral public key; sending to a second party, by the first party, the first-party derived ephemeral public key for validation; receiving from the second party, by the first party, a second-party derived ephemeral public key and a second-party signature; responsive to receiving the second-party derived ephemeral public key and the second-party signature, verifying, by the first party, that the second-party derived ephemeral public key is valid; if the second-party derived ephemeral public key is not valid, terminating, by the first party, the KC-AKE with derived ephemeral keys protocol; if the second-party derived ephemeral public key is valid, then:
