Abstract
Embodiments establish, at a first entity, a common secret key ('k') for encrypted data communication during a key exchange between the first entity and a second entity. Embodiments select a first private key of the first entity and receive, from the second entity, a second public key (“A”) of the second entity. Embodiments receive from the second entity a first verification value (“C”). Embodiments generate a first random number (“e”) and send e to the second entity and receive from the second entity a second verification value (“D”) in response to the first random number, where D, when properly generated, is based at least on r, e and the second private key. Embodiments determine, based on C and D, whether A is properly generated and when A is not properly generated, end the key exchange.
