The number of connected devices, machines, sensors, or simply things are linked with each other over open communication networks on the internet of things (IoT) has exploded. Processes are remotely monitored through networks of smart devices. And every device represents a potential entry point for malicious intrusion – into the device itself, or the network to which it’s connected. These new security threats pose technology challenges in securing and stabilizing such large systems. In such an environment, secure device identity is an essential requirement for clone-resistant operational security.
