Ironwood Key Agreement Protocol by Veridify Security is a fast, low-energy, quantum-resistant key agreement protocol designed for connected devices. It enables two parties to authenticate each other and generate a shared secret over an open channel without prior communication. Ironwood Key Agreement Protocol is optimized for cost, power, and size, making it ideal for the smallest devices. It performs calculations using small operands (8- to 32-bits), compared to the larger operands required by traditional methods like ECC and RSA, making it suitable for low-resource environments such as 8-, 16-, and 32-bit microcontrollers. Ironwood Key Agreement Protocol is available for both software and hardware implementations and is designed to deliver superior performance in IoT cybersecurity where other methods cannot.
