Patent Images
1. A method comprising:
- receiving, by a waveguide system, electromagnetic waves at a physical interface of a transmission medium that propagate without utilizing an electrical return path, wherein the electromagnetic waves are guided by the transmission medium, and wherein the electromagnetic waves have a non-optical frequency range; and
determining whether the electromagnetic waves are being received from a second network device according to a fingerprint of the electromagnetic waves.

Abstract
Aspects of the subject disclosure may include, for example, accessing a profile including an expected fingerprint of expected parameters for received signals associated with a network path comprising a wired connection between network devices, comparing a fingerprint with the expected fingerprint where the fingerprint is generated from parameters measured from a signal, and authenticating a network device along the network path associated with the transmitting of the signal according to the comparing. Other embodiments are disclosed.
