| DWPI Title: Data encryption system, has light source arranged to transmit input data signal to random optical element, where image received by detector is applied to sensing algorithm to generate transfer function to estimate input data signal |
| Abstract: A system or method for encryption of data includes a light source, a random optical element and a light detection element. The light source is arranged to transmit an input data signal to the random optical element. The light source is incident on the random optical element such that the input data signal is randomly scattered by the random optical element to generate an image at on the detector disposed at an output of the random optical element. The image received by the detector is applied to a compressive sensing algorithm to generate a transfer function. The transfer function defines a relationship between the input data signal and the image to enable estimation and reconstruction of the input data signal. |
| Use: Data encryption system. |
| Advantage: The system realizes secure communication and authentication between parties by using COPUF systems after initial calibration without an individual system so as to assure authenticity of communication provided parties. |
| Novelty: The system has a light source arranged to transmit an input data signal to a random optical element (14) when the light source is incident on the random optical element, where the input data signal is randomly scattered by the random optical element to generate an image at on a detector at an output of the random optical element and the image received by the detector is applied to a compressive sensing algorithm to generate a transfer function that defines a relationship between the input data signal and the image to enable estimation and reconstruction of the input data signal. |
