Recommendation for Stateful Hash-Based Signature …

WebThe eXtended Merkle Signature Scheme (XMSS) [BDH11] is the latest stateful hash-based signature scheme. It has the smallest signatures out of such schemes and comes with a multi-tree variant that solves the problem of slow key generation. Moreover, it can be shown that XMSS is secure, making only mild assumptions on the underlying hash function WebAs stateful hash-based signatures do not meet the API requested for signatures, this standardization effort will be a separate process from the one outlined in the call for proposals. It is expected that NIST will only approve a stateful hash-based signature standard for use in a limited range of signature applications, such as code signing ... WebAutomated fuzzy hash based signature collection is disclosed. A set of candidate fuzzy hashes corresponding to a set of false negative samples is received.

"WebSep 12, 2024 · $\begingroup$ @MarcoAuréliodaSilva: you can, of course, do that with any signature algorithm. The issue with stateful hash-based signatures is not the limit on the number of signatures (which you can easily make quite large), but the requirement to reliably keep state - signing a number of messages at once doesn't help with that $\endgroup$ – " - Stateful hash based signatures

Use of the SPHINCS+ Signature Algorithm in the Cryptographic …

WebMost hash-based signature schemes are stateful, meaning that signing requires updating the secret key, unlike conventional digital signature schemes. For stateful hash-based … WebFor stateful hash-based signature schemes, signing requires keeping state of the used one-time keys and making sure they are never reused. The XMSS, LMS and BPQS schemes are stateful, while the SPHINCS scheme is stateless. SPHINCS signatures are larger than XMSS and LMS signatures. BPQS has been designed specifically for blockchain systems.
