Multivariate Public Key Cryptosystem (MPKC) seem to be promising toward future digital
security even in the presence of quantum adversaries. MPKCs derive their security from the …

This work introduces new key recovery attacks against the Rainbow signature scheme,
which is one of the three finalist signature schemes still in the NIST Post-Quantum …

Abstract The National Institute of Standards and Technology is in the process of selecting
one or more public-key cryptographic algorithms through a public, competition-like process …

Abstract The National Institute of Standards and Technology is in the process of selecting
publickey cryptographic algorithms through a public, competition-like process. The new …

The contributions of this paper are twofold. First, we simplify the description of the
Unbalanced Oil and Vinegar scheme (UOV) and its Rainbow variant, which makes it easier …

We present an overview of quantum-safe cryptography (QSC) with a focus on post-quantum
cryptography (PQC) and information-theoretic security. From a cryptographic point of view …

The HFE cryptosystem is one of the most popular multi-variate schemes. Especially in the
area of digital signatures, the HFEv-variant offers short signatures and high performance …

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 …

Most coding theory experts date the origin of the subject with the 1948 publication of A
Mathematical Theory of Communication by Claude Shannon. Since then, coding theory has …

Abstract The Rank Decoding problem (RD) is at the core of rank-based cryptography.
Cryptosystems such as ROLLO and RQC, which made it to the second round of the NIST …
