SDitH

A NIST PQC Round 3 candidate for the additional digital signatures process

SDitH (Syndrome Decoding in the Head) is a post-quantum digital signature scheme based on the syndrome decoding problem, currently a Round 3 candidate in NIST’s PQC “additional signatures” standardisation process. I’m a co-author on the submission, alongside Carlos Aguilar-Melchor, Thibauld Feneuil, Nicolas Gama, Shay Gueron, David Joseph, Antoine Joux, Edoardo Persichetti, Tovohery Hajatiana Randrianarisoa, Matthieu Rivain, and Dongze Yue.

For a hardware implementation, see SDitH in Hardware.
