Two multivariate digital signature schemes, Rainbow and GeMSS, made it into the third
round of the NIST PQC competition. However, neither made its way to being a standard due …

We present a new method for transforming zero-knowledge protocols in the designated
verifier setting into public-coin protocols, which can be made non-interactive and publicly …

We present qTESLA, a post-quantum provably-secure digital signature scheme that exhibits
several attractive features such as simplicity, strong security guarantees against quantum …

In this paper, we show how to use the Matrix Code Equivalence (MCE) problem as a new
basis to construct signature schemes. This extends previous work on using isomorphism …

Signature schemes based on the MPC-in-the-head approach (MPCitH) have either been
designed by taking a proof system and selecting a suitable symmetric-key primitive (Picnic …

Picnic is a NIST PQC Round 3 Alternate signature candidate that builds upon symmetric
primitives following the MPC-in-the-head paradigm. Recently, researchers have been …

Quantum computing is a game-changing technology that will push the boundaries of
cybersecurity and cryptography of power infrastructures including distributed energy …

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 …

Post-quantum signature schemes based on the MPC-in-the-Head (MPCitH) paradigm are
recently attracting significant attention as their security solely depends on the one-wayness …

We revisit the alternating moduli paradigm for constructing symmetric key primitives with a
focus on constructing highly efficient protocols to evaluate them using secure multi-party …
