Abstract
An authentication system for a computing environment uses physically unclonable functions (PUFs) to authenticate requests to perform an action in the environment. The system receives, from an imaging device, an image of a physically unclonable object associated with the electronic request. The system then obtains from a computer server operating within the system via an encrypted communication channel, a challenge associated with the object. The system uses extraction parameters encoded within the challenge to transform a portion of the image and produce authentication data representing a response to the challenge. The system extracts, using the extraction parameters, the authentication data from the image and determines whether the challenge and response match and the request is authenticated.
