Abstract

Techniques and methods are described to perform physical layer authentication, using a received signal transmitted from a communication device that has been already authenticated previously. To identify a potential attacker, a current value of a plurality of physical layer L1 parameters of the wireless channel is determined, with said L1 parameters describe for a sparse channel. A value of the plurality of L1 parameters that have been stored at the previous authentication are obtained from a storage. Base on the current value and the stored value of the plurality of L1 parameters, the communication device is authenticated. In this way, the physical layer authentication may provide for a robust and reliable authentication of communication devices in sparse communication channels, including static and dynamic wireless environments.
