Increasing Physical Layer Security through Scrambled Codes and ARQ [PDF]

open access: yes, 2011
We develop the proposal of non-systematic channel codes on the AWGN wire-tap channel. Such coding technique, based on scrambling, achieves high transmission security with a small degradation of the eavesdropper's channel with respect to the legitimate ...

Optimal Beamforming for Physical Layer Security in MISO Wireless Networks [PDF]

open access: yes, 2018
A wireless network of multiple transmitter-user pairs overheard by an eavesdropper, where the transmitters are equipped with multiple antennas while the users and eavesdropper are equipped with a single antenna, is considered.

Channel-Aware Randomized Encryption and Channel Estimation Attack

open access: yesIEEE Access, 2017
In this paper, we study the channel-aware (CA) randomization for a simple physical-layer encryption scheme and show that the probability of successful attack becomes very low by CA randomization when the known plain-text attack is carried out.
