Ensuring Trust and Security in the Industrial IoT

Industrial Internet of Things (IOT) is a distributed network of smart sensors that enables precise control and monitoring of complex processes over arbitrary distances. The great advantage of the industrial IoT is counterbalanced by a security weakness. The insertion of a smart device capable of extracting protected data or malicious actions can infect the whole network with relative ease. Thus it becomes imperative to discover whether or not new devices have the right capabilities and compatibilities with other sensors. This article presents a zero knowledge protocol that achieves precisely that objective while keeping the sensor data private.
