  • Publication number: 20210365553
    Abstract: To provide a control device capable of minimizing side-channel leaks that can be generated before completion of an analog-to-digital conversion by a PUF implemented as a physical parameter and making attacks difficult. The control device provided includes a device unit that has regularly arranged analog devices such as pixel array, and a readout control unit that executes readouts that are a mixture of a real PUF readout (first readout) that generates unique information for the device unit and a dummy PUF readout (second readout) that does not generate unique information for the device.
