Abstract

The disclosure relates to a communication device (110a) for communicating data via a first communication network (141) with a second communication network (131), the communication device (110a) comprising: a processor (111) configured to process data (300a, 300b) comprising a payload section (301) and a first header section (302); a memory (113, 115) configured to store the data (300a, 300b); and a radio transmitter (117) configured to transmit the processed data via the first communication network (141) to neighboring communication devices (110b, 110c) of the second communication network (131) and/or a base station (130) of the second communication network (131), wherein the processor (111) is configured to append a second header section (303) to the data (300a, 300b) in accordance with a tunneling protocol (142, 143, 144) for tunneling the data (300a, 300b) through the first communication network (141) to the second communication network (131) and to append a cryptographic token (304) to the data (300a, 300b) to authenticate the payload section (301) of the data, wherein the cryptographic token (304) is independent from the second header section (303).
