PRF advantage refers to the advantage of a particular algorithm (or adversary) in distinguishing a pseudorandom function (PRF) from a truly random function. In cryptography, a pseudorandom function is a function that is efficient to compute and indistinguishable from a random function by any efficient (polynomial-time) adversary. The concept is crucial in evaluating the security of cryptographic primitives.
