Cryptography - Nonce (Number Only used once)

1 - About

In cryptography, a nonce is an arbitrary number that can only be used once. A value that is used only once.

It is similar in spirit to a nonce word, hence the name.

It is often a random or pseudo-random number issued in an authentication protocol to ensure that old communications cannot be reused in replay attacks.
