Abstract
A first server exchanges with a second server a master (symmetric) key(s). The first server sends to the first application the master key(s). The second server generates dynamically a first derived key by using a generation parameter(s) and a first master key. The second server sends to the second application the first derived key and the generation parameter(s). The second application generates and sends to the first application a first (key possession) proof and the generation parameter(s). The first application verifies successfully by using the generation parameter(s), the first master key and the first proof, that the first proof has been generated by using the first derived key, generates and sends to the second application a second (key possession) proof. The second application verifies successfully that the second proof has been generated by using the first derived key, as a dynamically generated and proven shared key.
