WOTS+ (Winternitz One-Time Signature)
Definition
WOTS+ is a hash-based one-time signature scheme used within SPHINCS+ and other hash-based signature systems. Each WOTS+ key pair can securely sign exactly one message. SPHINCS+ manages many WOTS+ instances through Merkle trees to enable multiple signings from one public key.
Technical Explanation
WOTS+ signs messages by iteratively hashing secret key components based on message digits. The Winternitz parameter w trades signature size for computationโhigher w means smaller signatures but more hashing. WOTS+ improvements over original WOTS include better security proofs and tighter parameters.
Security is unconditional given hash function security: an attacker seeing one signature cannot forge another. The limitationโeach key signs onceโis resolved by SPHINCS+ using Merkle trees to organize many WOTS+ key pairs under one root.
SynX Relevance
Every SPHINCS+ signature in SynX internally uses WOTS+ for the actual signing operation. The SPHINCS+ structure handles key management so users experience stateless signing while WOTS+ provides the core quantum-resistant security. This layered approach combines efficiency with robustness.
Frequently Asked Questions
- Why "one-time" if I can sign many transactions?
- SPHINCS+ manages many WOTS+ instances internally; you never reuse the same one-time key.
- What happens if a WOTS+ key is reused?
- Security degradesโattackers can forge signatures. SPHINCS+ prevents this through careful state management.
- Is WOTS+ fast?
- Signing requires many hash computations; it's slower than lattice signatures but fast enough for transactions.
