Abstract: An RF testing method is applied between a testing instrument and multiple devices under test at least including a first DUT and a second DUT. The testing instrument includes a signal generator and a signal analyzer. A sync signal is sent to the testing instrument and the first DUT, so that the first DUT occupies the signal generator to receive a testing signal from the signal generator. The first DUT sends an uplink signal to the signal analyzer based on the testing signal to occupy the signal analyzer for signal analysis at a first point in time. The sync signal is sent to the testing instrument and the second DUT, so that the second DUT occupies the signal generator to receive the testing signal from the signal generator at a second point in time. The first point in time is parallel to the second point in time.

Abstract: A 3D physical unclonable functions (PUF) system produced based on harnessing the out-of-plane crumpling of a layer of 2D material during shrinkage of a substrate carrying such layer. The structural details of the so-formed 3D PUF pattern are extracted from the tags in a layer-by-layer fashion using confocal laser microscopy imaging and then reconstructed to form the 3D PUF keys and stored in the database, serving as a secure anti-counterfeiting PUF that demonstrates encoding capacity in excess of 1040,000,000. Authentication is performed with a customized trained Siamese neural network framework in a matter of few minutes in a fashion that does not depend on rotation, linear translation, tilt, variations of contrast and/or resolution of the extracted optical images.
