This paper addresses the performance bottleneck of SPHINCS+, a post-quantum secure signature scheme, by leveraging GPU acceleration. It introduces HERO-Sign, a novel implementation that optimizes signature generation through hierarchical tuning, compiler-time optimizations, and task graph-based batching. The paper's significance lies in its potential to significantly improve the speed of SPHINCS+ signatures, making it more practical for real-world applications.
