ePrint Report: SDitH in Hardware

Sanjay Deshpande, James Howe, Jakub Szefer, Dongze Yue

This work presents the first hardware realisation of the Syndrome-Decoding-in-the-Head (SDitH) signature scheme, which is a candidate in the NIST PQC process for standardising post-quantum secure digital signature schemes. SDitH's hardness is based on conservative code-based assumptions, and it uses the Multi-Party-Computation-in-the-Head (MPCitH) construction.
This is the first hardware design of a code-based signature scheme based on traditional decoding problems and only the second for MPCitH constructions, …
