WebWe describe a lightweight protocol for oblivious evaluation of a pseudorandom function (OPRF) in the presence of semihonest adversaries. In an OPRF protocol a receiver has an input r; the sender gets output s and the receiver gets output F(s; r), where F is a pseudorandom function and s is a random seed.

Denoting the pseudorandom function by F,thein-put of party P1 by X, and the input of party P2 by Y, we have that at the end of this stage party P2 holds the set {Fk(y)}y∈Y while P1 has learned nothing.
