Physical Layer Security in N-Pair NOMA-PLNC Wireless Networks

IEEE Access, 2022
In this paper, the effective end-to-end secure communication of N-pair cellular network is studied. Promising multiple access scheme known as non-orthogonal multiple access (NOMA) and physical layer network coding (PLNC) scheme are employed to improve ...

Channel-Aware Randomized Encryption and Channel Estimation Attack

IEEE 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 over Correlated Erasure Channels

, 2011
We explore the additional security obtained by noise at the physical layer in a wiretap channel model setting. Security enhancements at the physical layer have been proposed recently using a secrecy metric based on the degrees of freedom that an attacker
