Miraidon: MinRank Identification

Ryann Cartor, Clemson University
Freeman Slaughter, University of South Florida
Abstract

We introduce $\textit{Miraidon}$, a new family of MinRank-based post-quantum signature schemes built from a novel zero-knowledge proof system. Our primary construction, $\textit{Miraidon-S}$, is a digital signature scheme with competitive public key and signature sizes, improved soundness parameters, and security based on the hardness of the MinRank problem. Building on this framework, we further construct $\textit{Miraidon-RS}$, a ring signature scheme, and introduce $\textit{Miraidon-LRS}$, the first linkable ring signature scheme based on the MinRank problem. We present concrete parameters and comparisons with contemporary lattice- and code-based ring and linkable ring signatures, showing that MinRank provides a promising foundation for efficient advanced post-quantum signature primitives.
