Abstract
The present invention relates to a receiver (2200) for recognizing blinding attacks in a quantum encrypted channel (1300) comprising an optical fiber, comprising a multipixel detector (2210) comprising a plurality of pixels, and configured to be illuminated by a light beam outputted by the optical fiber, and a processing unit (2220) connected to the multipixel detector (2210) and configured to determine the presence of a blinding attack if a predetermined number of pixels detects light within a predetermined interval. The invention further relates to the use of the receiver (2200) for recognizing blinding attacks in a quantum encrypted channel (1300) and to a method for recognizing blinding attacks in a quantum encrypted channel (1300).
