WebAn Oblivious Pseudorandom Function (OPRF) is a two-party protocol between client and server for computing the output of a Pseudorandom Function (PRF). The server provides the PRF secret key, and the client provides the PRF input. At the end of the protocol, the client learns the PRF output without learning anything about the PRF secret key, and the server … WebSoK: All or Nothing - A Postmortem of Solutions to the Third-Party Script Inclusion Permission Model and a ...
