Abstract:

MPC in the Head (MPCitH) is a paradigm for building zero-knowledge proof from multi-party computation. Later, the MPCitH paradigm was found powerful in post-quantum signatures. Recently, it has led to significant improvements in post-quantum signatures from symmetric-key and code-based primitives. In this talk, I will introduce MPC/VOLE-in-the-head, its application in post-quantum signatures, and the state of the art in this direction.
