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.

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.

Wireless Physical Layer Security

open access: yesEURASIP Journal on Wireless Communications and Networking, 2009
Security is a critical issue in multi-user wireless networks in which secure transmissions are becoming increasingly difficult to obtain in highly mobile and distributed environments. Interest in this area has exploded since 2000, motivated by the rise of wireless networking in general and by the increasing interest in large mobile networks with light ...

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 ...

A cross-layer approach to message authentication based on sparse representation for wireless body area networks

open access: yesInternational Journal of Distributed Sensor Networks, 2017
Due to personal privacy, information security is a particularly important issue in wireless body area networks. Although current communication protocol has considered the security, there is still a risk that lapses in physical layer security may be a ...
