Exploiting the physical in cyber-physical systems: On the practical use of physical-layer information to enhance system security [PDF]

open access: yes, 2022
This thesis argues that cyber-physical systems are, by their very nature, at risk from physical-layer attacks as well as cyber attacks. The proliferation of cheap and easy-to-use sensing and actuation technologies has drastically lowered the bar for ...

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.
