Thus, a random function can be considered to map each input independently at random to any one of the possible outputs.{{clarify|date=February 2012}} Viewed this way it is an idealization of a [[cryptographic hash function]].
A random function is a useful building block in enabling [[cryptographic protocol]]s. However, there are scenarios where it is not possible for mutually distrustful parties to agree on a random function (i.e., [[coin flipping]] is impossible).{{Citation needed|date=December 2011}} Therefore, cryptographers study models which explicitly allow for the use of a random function or a related object. See [[random oracle model]], [[common reference string model]].
