Abstract
A system and method are described for validating an IoT device. For example, a method in accordance with one embodiment comprises: generating a first random value to be used as a first offset into a first block of program code of an Internet of Things (IoT) device; transmitting a challenge request message to the IoT device, the challenge request including the first offset or data based on the first offset; receiving a challenge response message transmitted by the IoT device, the challenge response message comprising first authentication data for the first block of IoT device program code; and using the first authentication data to attempt to validate the first block of program code.
