Description: WalnutDSA TM: a quantum resistant group theoretic digital signature algorithm. In 2005 I. Anshel, M. Anshel, D. Goldfeld, and S. Lemieux introduced E-Multiplication TM, a quantum-resistant, group-theoretic, one-way function which can be used as a basis for many different cryptographic applications. This one-way function was specifically designed for constrained devices, running extremely quickly and requiring very little code. This paper introduces WalnutDSA, a new E-Multiplication-based public-key method which provides efficient verification, allowing low-power and constrained devices to quickly and inexpensively validate digital signatures (e.g., a certificate or authentication). It presents an in-depth discussion of the construction of the digital signature algorithm, analyzes the security of the scheme, provides a proof of security under EUF-CMA, and discusses the practical results from implementations on several constrained devices.
