Abstract:
An authentication device is provided that authenticates an electronic device based on the responses from distinct types of physically unclonable functions. The authentication device receives a device identifier associated with the electronic device. It then sends one or more challenges to the electronic device. In response, the authentication device receives one or more responses from the electronic device, the one or more responses including characteristic information generated from two or more distinct types of physically unclonable functions in the electronic device.
