Abstract
Various systems for providing secure signatures based on post-quantum computing are provided. The systems allow may one-time signatures ('OTS') to be based on the same public key. The systems provide for efficient use of OTS signatures with blockchains. The systems provide for rapid verification of signatures. The systems provide for caching for Winternitz-based OTS schemes and for use of short checksum.
