Welcome to the resource topic for 2023/1685

Title:
MPC in the head using the subfield bilinear collision problem

Authors: Janik Huth, Antoine Joux

Abstract:

In this paper, we introduce the subfield bilinear collision problem and use it to construct an identification protocol and a signature scheme. This construction is based on the MPC-in-the-head paradigm and uses the Fiat-Shamir transformation to obtain a signature.
