Efficient TCitH-Based Alternatives to SLH-DSA: Cross-Layer ASIC Design of Mirath

To address the security risks posed by quantum computers, the U.S. National Institute of Standards and Technology NIST has standardized the post-quantum signature schemes ML-DSA, FN-DSA, and SLH-DSA. While ML-DSA and FN-DSA are lattice-based, SLH-DSA relies on hash-based assumptions. To support...
