WebIn this tutorial we survey various incarnations of pseudorandom functions, giving self-contained proofs of key results from the literature. Our main focus is on feasibility results … Websoftware package your are using. From now on we will refer to pseudo random number generators simply as random number generators (RNG). The typical structure of a random number generator is as follows. There is a ﬁnite set S of states, and a function f : S → S. There is an output space U, and an output function g : S → U.

WebA pseudorandom generator allows us to take a small amount of uniformly sampled bits, and “amplify” them into a larger amount of uniform-looking bits. A PRG must run in polynomial time, so the length of its pseudorandom output can only be polynomial in the security parameter. But what if we wanted even more pseudorandom output?
