Systems and Methods for Classifying PUF Signature Modules of Integrated Circuits - A simplified explanation of the abstract
This abstract first appeared for US patent application 18446838 titled 'Systems and Methods for Classifying PUF Signature Modules of Integrated Circuits
Simplified Explanation
- The patent application describes a method for determining the reliability of a physically unclonable function (PUF) cell in a device. - The method involves providing activation signals to the PUF cell under different conditions and determining the output of the PUF cell for each condition. - The number of times the PUF cell output is consistent is then determined, indicating its reliability. - Based on the determined number of consistent outputs, a device classification value is determined for a plurality of PUF cells. - The innovation aims to provide a reliable and accurate assessment of the reliability of PUF cells in a device.
Original Abstract Submitted
Systems and method are provided for determining a reliability of a physically unclonable function (PUF) cell of a device. One or more activation signals are provided to a PUF cell under a plurality of conditions. A PUF cell output provided by the PUF cell under each of the plurality of conditions is determined. A determination is made of a number of times the PUF cell output of the PUF cell is consistent. And a device classification value is determined based on the determined number of times for a plurality of PUF cells.
