MPSpeed: Implementing and Optimizing MPC-in-the-Head Digital Signatures in Hardware
Ingrid Verbauwhede
The Multi-Party Computation (MPC)-in-the-Head (MPCitH) framework enables the construction of post-quantum Digital Signature Algorithms (DSAs), offering competitive public key sizes. However, this comes at a cost of high computational complexity, resulting in high signature generation and verification times.
In this work, we propose a compact and efficient hardware accelerator for Mirath, an MPCitH-based DSA and candidate in the ongoing NIST PQC standardization effort. We propose a series of alg
