Abstract: A communication system for authenticate a second communication device to a first communication device, wherein the communication system comprises a physical connection between a first communication device and a second communication device, where a first message may be transmitted from the first communication device, via the physical connection, to the second communication device. Furthermore, the communication system comprises a non-physical connection between the first communication device and the second communication device, where a second message may be transmitted from the first communication device, via the non-physical connection, to the second communication device, and wherein the second communication device may be configured to evaluate the first message and the second message based on a matching criteria, and if the evaluation of the first message and the second message fulfills the matching criteria then the second communication device may be configured to transmit an acceptance to the first communication device.
