    Abstract: A method is provided for using obtaining a reproducible device identifier from a physically unclonable function. An authentication device may receive a first physically unclonable function (PUF) dataset from the electronic device, the first PUF dataset including characteristic information generated from a physically unclonable function in the electronic device. The authentication device may then identify a pre-stored PUF dataset corresponding to the electronic device. Authentication of the electronic device may be performed by correlating the pre-stored PUF dataset and the first PUF dataset for the electronic device, wherein such correlation is based on a pattern or distribution correlation the pre-stored PUF dataset and the first PUF dataset. Because such correlation is performed on datasets, and not individual points, systematic variations can be recognized by the correlation operation leading to higher correlation than point-by-point comparisons.

    Abstract: One feature pertains to a computing device that includes an input interface, a communication interface, and a processing circuit that is adapted to receive a request from an application to authorize an action and generate a dynamic access code associated with the action. The processing circuit also transmits a message to a secondary display device that includes information data associated with the action and the dynamic access code for display on a display of the secondary display device. The processing circuit authorizes the action received from the application if the dynamic access code is entered into the input interface. Multiple, unique dynamic codes may also be associated with different actions the application may make requests for, which are also transmitted to the secondary display device for display.

    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.
