Abstract

   This document specifies the conventions for using the Walnut Digital
   Signature Algorithm (WalnutDSA) for digital signatures with the CBOR
   Object Signing and Encryption (COSE) syntax.  WalnutDSA is a
   lightweight, quantum-resistant signature scheme based on Group
   Theoretic Cryptography with implementation and computational
   efficiency of signature verification in constrained16807
   environments, even on 8- and 16-bit platforms.

   The goal of this publication is to document a way to use the
   lightweight, quantum-resistant WalnutDSA signature algorithm in COSE
   in a way that would allow multiple developers to build compatible
   implementations.  As of this publication, WalnutDSA has not been
   endorsed by the IETF.
