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.

Physical layer security

open access: yes
This deliverable discloses closed form expressions for secrecy capacity analysis and the design of PLS techniques to achieve secure MTC transmission by utilising NOMA techniques. It provides inputs to Task 4.3 in WP4 for integrated link level and system level security measures; code implementation (e.g., in C) for WP5 system prototyping.

Physical Layer Security in the Presence of Interference [PDF]

open access: yesIEEE Wireless Communications Letters, 2017
We evaluate and quantify the joint effect of fading and multiple interferers on the physical-layer (PHY) security of a system consisted of a base-station (BS), a legitimate user, and an eavesdropper. To this end, we present a novel closed-form expression for the secrecy outage probability, which takes into account the fading characteristics of the ...
