NIST Accepts SecureRF’s WalnutDSA for Evaluation

SecureRF’s Walnut Digital Signature Algorithm (WalnutDSA) has been accepted by the National Institute of Standards and Technology (NIST) for evaluation as a standard for post-quantum, public-key cryptography. NIST expects to perform multiple rounds of evaluation over a period of three to five years on all of the methods submitted. WalnutDSA is a fast, easy-to-implement, low-energy solution…

New Paper: Kayawood Key Agreement Protocol

SecureRF has published a new paper, “Kayawood, a Key Agreement Protocol,” which introduces a group-theoretic key agreement protocol that leverages the known NP-Hard shortest word problem (among others) to provide an Elgamal-style, Diffie-Hellman-like method. The paper also discusses the implementation of and behavioral aspects of Kayawood, introduces new methods to obfuscate braids using Stochastic Rewriting, and…

Ask SecureRF: AES for Authentication?

Question: AES is used successfully all the time. Why shouldn’t we use AES for authentication? SecureRF: AES is a range of symmetric encryption mechanisms widely available on many devices—for free. You can use AES to authenticate a device, but it typically requires the connection to a database or network and lot of other processing that…
