N2 - A randomized encoding of a function f(x) is a randomized function f(x, r), such that the “encoding” f(x, r) reveals f(x) and essentially no additional information about x. Randomized encodings of functions have found many applications in different areas of cryptography, including secure multiparty computation, efficient parallel cryptography, and verifiable computation. We initiate a complexity-theoretic study of the class SRE of languages (or boolean functions) that admit an efficient statistical randomized encoding. That is, f(x, r) can be computed in time poly(|x|), and its output distribution on input x can be sampled in time poly(|x|) given f(x), up to a small statistical distance. We obtain the following main results.
