ePrint Report: A post-quantum Distributed OPRF from the Legendre PRF

Novak Kaluderovic, Nan Cheng, Katerina Mitrokotsa

A distributed OPRF allows a client to evaluate a pseudorandom function on an input chosen by the client using a distributed key shared among multiple servers. This primitive ensures that the servers learn nothing about the input nor the output, and the client learns nothing about the key.
We present a post-quantum OPRF in a distributed server setting, which can be computed in a …
