SecureRF Corporation (Shelton, Connecticut) is a provider of ‘quantum-resistant’ security tools for the IoT; now in ST’s Partner Program, users will gain access to ST products embedded with SecureRF’s authentication and data protection solutions, which are suited for low-resource 32-, 16-, and 8-bit processors and other small IoT devices.
Low-resource “edge” devices bring inherent limitations that make securing them a challenge; they require secure authentication and data protection, but may not always possess the computing and memory resources to incorporate contemporary security solutions with acceptable runtimes and resource allocation. SecureRF products address this challenge with authentication and data protection solutions that are designed to meet the requirements for the compact operating footprint of ultra-low-energy edge devices, as well as helping to extend the useful working life of battery-powered IoT processors.
Specifically, SecureRF’s Walnut Digital Signature Algorithm (WalnutDSA) is an ultra-fast signature verification solution that uses the company’s breakthrough Group Theoretic Cryptography algorithm — the first “linear-in-time” method. WalnutDSA is said to be significantly more efficient than current solutions such as the Elliptic Curve Cryptography’s (ECC) Digital Signature Algorithm (ECDSA). A second key technology from SecureRF is its Ironwood Key Agreement Protocol (Ironwood KAP), a Diffie-Hellman-like authentication protocol. Optimized for both cost and power, Ironwood promises at least 30 times more efficient performance than ECC and gives IoT developers a tool that is quantum-resistant to all known attacks.
