This paper presents MQ on my Mind (MQOM), a digital signature scheme based on the
difficulty of solving multivariate systems of quadratic equations (MQ problem). MQOM has …

Abstract The Fujisaki-Okamoto (FO) transformation is used in most proposals for post-
quantum secure key encapsulation mechanisms (KEMs) like, eg, Kyber. The security …

A popular way to build post-quantum signature schemes is by first constructing an
identification scheme (IDS) and applying the Fiat-Shamir transform to it. In this work we …

Zero-Knowledge (ZK) protocols allow a prover to demonstrate the truth of a statement
without disclosing additional information about the underlying witness. Code-based …

This work presents the first hardware realisation of the Syndrome-Decodingin-the-Head
(SDitH) signature scheme, which is a candidate in the NIST PQC process for standardising …

The eight-volume set LNCS 14438 until 14445 constitutes the proceedings of the 29th
International Conference on the Theory and Application of Cryptology and Information …

We present ReSolveD, a new candidate post-quantum signature scheme under the regular
syndrome decoding (RSD) assumption for random linear codes, which is a well-established …

This report covers our work on the submissions to the KpqC competition. We analyzed all
submitted KEMs and signature systems. For those that withstood cryptanalysis, we checked …

This report covers our analysis (security, proofs, efficiency) of the Round-2 candidates to the
Korean post-quantum competiton KpqC. Signature systems covered in the report are AIMer …

The recent VOLE-based interactive zero-knowledge (VOLE-ZK) protocols along with non-
interactive zero-knowledge (NIZK) proofs based on MPC-in-the-Head (MPCitH) and VOLE …
