Sok oblivious pseudorandom functions
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 … WebMar 1, 2024 · This work shows that key-recovery attacks against the Legendre PRF are equivalent to solving a specific family of multivariate quadratic (MQ) equation system over a finite prime field, and builds novel cryptographic applications of the PRF, e.g., verifiable random function and (verifiable) oblivious (programmable) PRFs.
