SecureRF Corporation showcased its quantum-resistant asymmetric cryptography for low-resource Internet of Things (IoT) devices at Sensors Expo 2017. SecureRF demonstrated that its WalnutDSA and Ironwood key agreement protocol offer more efficient performance than Elliptic Curve Cryptography (ECC) on a small 8-bit processor, which is the class of processor that you’d likely find on a sensor or actuator device.
 
Most IoT devices, like the 8-bit processor in SecureRF’s demonstration, require authentication and data protection but don’t have the computing and memory resources to incorporate contemporary security solutions with acceptable runtimes and resource allocation.
 
SecureRF addresses these issues by providing authentication and data protection for IoT devices with security solutions that are up to 60× more efficient than ECC and consume more than 140× less energy.
 
WalnutDSA verifies that a message has been signed with a trusted third-party’s private key.  Ironwood KAP is a Diffie-Hellman-like authentication protocol that establishes a shared secret between two parties. A CMAC of the shared secret (combined with a nonce) is used to mutually authenticate the parties.
