Rārangi ihirangi:
- <p class="p1">We introduce Ladhe, a hash-based signature scheme whose private key is an ascending</p> <p class="p1">tuple of distinct primes summing to a public prime P. The public key is the hash of an</p> <p class="p1">indexed-pair compression of these primes. We present a one-time variant and describe its</p> <p class="p1">extension to a many-time scheme via standard Merkle aggregation. Security reduces to</p> <p class="p1">preimage resistance of the underlying hash function (SHA-256 in our reference), the same</p> <p class="p1">foundation as SPHINCS+. The arithmetic structure of the private key enables compact</p> <p class="p1">signatures (the primes themselves, no Merkle path in the one-time case) and structural</p> <p class="p1">verification (a fixed number of primality tests plus one hash evaluation). We give the full</p> <p class="p1">construction, formal security analysis in the random oracle model, an IANA-registered al-</p> <p class="p1">gorithm identifier (Private Enterprise Number 65644, registered April 2026), a reference</p> <p class="p1">Python implementation, and a public cryptanalysis challenge. Efficient KeyGen at crypto-</p> <p class="p1">graphic parameter sizes remains open.</p>
