Use of the Walnut Digital Signature Algorithm with CBOR Object Signing
and Encryption (COSE)

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.
