[{$pagename}] ("number used once") is, typically a randomly generated value (technically does not need to be a number) that's associated with a [message] in a [cryptographic] scheme and must be unique within some specified scope (such as a given time interval, or a session).[1]
[{$pagename}] typically used to prevent [Replay attack].
For example, challenges used in challenge-response [authentication] [protocols] generally must not be repeated until [authentication] keys are changed, or there is a possibility of a [Replay attack].
Using a [{$pagename}] as a challenge is a different requirement than a [random] challenge, because a [{$pagename}] may be predictable.
[{$pagename}] may be used for an [Initialization Vector] it [MUST] only to be non-repeating and the required randomness is derived internally.
