SLasH-DSA: Breaking SLH-DSA Using an Extensible End-To-End Rowhammer Framework

As quantum computing advances, PQC schemes are adopted to replace classical algorithms. Among them is the SLH-DSA that was recently standardized by NIST and is favored for its conservative security foundations. In this work, we present the first software-only universal forgery attack on SLH-DSA,...
