Remarks

A nonce is a "number used once", often a random number used in an authentication protocol to ensure that old communications cannot be used in an attack by using replays.

If the nonce count is exceeded, the incoming message is rejected and a MessageSecurityException is thrown. Old nonces are removed in a timely manner.
