What FIPS 205: Stateless Hash-Based Digital Signature Standard requires
FIPS 205 (Stateless Hash-Based Digital Signature Algorithm) is a NIST-standardized quantum-resistant signature mechanism based on the SPHINCS+ construction. Unlike lattice-based schemes, it relies solely on the security of cryptographic hash functions, providing a robust backup against potential cryptanalytic breakthroughs in other PQC families.
