WebDec 8, 2024 · An oblivious PRF, or OPRF, is a protocol between a client and a server, where the server has a key k for a secure pseudorandom function F, and the client has an input x for the function. At the end of the protocol the client learns F ( k, x), and nothing else, and the server learns nothing. An OPRF is verifiable if the client is convinced that ...

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 …
WebIn recent years, oblivious pseudorandom functions (OPRFs) have become a ubiquitous primitive used in cryptographic protocols and privacy-preserving technologies.

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. how to setup ms office in new laptopWebJun 1, 2024 · SoK: Oblivious Pseudorandom Functions.
