An adversary with SS bits of memory obtains a stream of QQ elements that are uniformly drawn from the set {1,2,…,N}{1,2,…,N}, either with or without replacement. This corresponds to sampling QQ elemen...

At CRYPTO 2015, Minaud and Seurin introduced and studied the iterated random permutation problem, which is to distinguish the rr-th iterate of a random permutation from a random permutation. In this p...

An oracle chooses a function f from the set of n bits strings to itself, which is either a randomly chosen permutation or a randomly chosen function. When queried by an n-bit string w, the oracle comp...
