Abstract

This standard specifies the stateless hash-based digital signature algorithm (SLH-DSA). Digital signatures are used to detect unauthorized modifications to data and to authenticate the identity of the signatory. In addition, the recipient of signed data can use a digital signature as evidence in demonstrating to a third party that the signature was, in fact, generated by the claimed signatory. This is known as non-repudiation since the signatory cannot easily repudiate the signature at a later time. SLH-DSA is based on SPHINCS+, which was selected for standardization as part of the NIST Post-Quantum Cryptography Standardization process.
