Abstract
A method for generating at least one cryptographic key includes taking a plurality of images with an image sensor, in particular, a CMOS image sensor, capturing pixels of the image sensor in at least one section or area of the image sensor which have a predefined error depending on the images taken and determining at least one cryptographic key depending on the captured pixels, that have the error, wherein the predefined error corresponds to a random telegraph noise error.
