Artificial Noise Versus Artificial Noise Elimination: Redefining Scaling Laws of Physical Layer Security

Artificial noise AN is a key physical-layer security scheme for wireless communications over multiple-input multiple-output wiretap channels. Recently, artificial noise elimination ANE has emerged as a strategy to mitigate the impact of AN on eavesdroppers. However, the influence of ANE on the...

Helper-Assisted Coding for Gaussian Wiretap Channels: Deep Learning Meets PhySec

Consider the Gaussian wiretap channel, where a transmitter wishes to send a confidential message to a legitimate receiver in the presence of an eavesdropper. It is well known that if the eavesdropper experiences less channel noise than the legitimate receiver, then it is impossible for the...
