SPHINCS+
WebSPHINCS+ Small (NIST Level 1) SPHINCS+ Fast (NIST Level 1) Dilithium (NIST Level 5) 3000X faster signing / same size 150X faster signing / 2.5X smaller.

I understand each one of these alone, but I am still having a problem figuring out how to sign a message in SPHNICS. I understand the hyper-tree structure of layers of L-Trees (WOTS+ trees) where the final layer is the HORST tree. Here are my questions: Q1. scott edmondson architect
Breaking Category Five SPHINCS+ with SHA-256 NIST
WebAbstract We introduce SPHINCS+, a stateless hash-based signature framework. SPHINCS+ has significant advantages over the state of the art in terms of speed, signature size, and … WebAbstract SPHINCS+ is a hash-based digital signature scheme that was selected by NIST in their post-quantum cryptography standardization process. The establishment of a universal forgery on the seminal scheme SPHINCS was shown to be feasible in practice by injecting a fault when the signing device constructs any non-top subtree. WebNov 23, 2024 · SPHINCS+ was selected as a candidate digital signature scheme for standardization by the NIST Post-Quantum Cryptography Standardization Process. It offers security capabilities relying only on the security of cryptographic hash functions. However, it is less efficient than the lattice-based schemes. scott edmands
