Abstract
A device for generating a key has a multimode interferometer which can be coupled to a light source and has a light path having an electro-optical material, the light path being configured to obtain light at an input side, influence the light under the influence of a locally varying refraction index of the electro-optical material and provide influenced light at an output side. The device has a receiver configured to receive the influenced light at the output side, and has an evaluator configured to perform an evaluation based on the influenced light and to generate the key based on the evaluation.
