On the secrecy performance of RIS-enabled wireless communications over Nakagami-m fading channels
ICT Express, 2023 This paper examines the secrecy performance of reconfigurable intelligent surface aided wireless communication systems. Specifically, we derive the secrecy outage probability (SOP), intercept probability, probability of non-zero secrecy capacity, and ...

Physical Layer Security in Two-Way SWIPT Relay Networks with Imperfect CSI and a Friendly Jammer
Entropy, 2023 In this paper, the security of two-way relay communications in the presence of a passive eavesdropper is investigated. Two users communicate via a relay that depends solely on energy harvesting to amplify and forward the received signals.

On the Secrecy Capacity of Fading Channels [PDF]
2007 IEEE International Symposium on Information Theory, 2007 We consider the secure transmission of information over an ergodic fading channel in the presence of an eavesdropper. Our eavesdropper can be viewed as the wireless counterpart of Wyner's wiretapper. The secrecy capacity of such a system is characterized under the assumption of asymptotically long coherence intervals. We first consider the full Channel

The Secrecy Capacity of the MIMO Wiretap Channel [PDF]
IEEE Transactions on Information Theory, 2008 We consider the MIMO wiretap channel, that is a MIMO broadcast channel where the transmitter sends some confidential information to one user which is a legitimate receiver, while the other user is an eavesdropper. Perfect secrecy is achieved when the the transmitter and the legitimate receiver can communicate at some positive rate, while insuring that ...

On Secrecy Capacity Scaling in Wireless Networks [PDF]
IEEE Transactions on Information Theory, 2010 This work studies the achievable secure rate per source-destination pair in wireless networks. First, a path loss model is considered, where the legitimate and eavesdropper nodes are assumed to be placed according to Poisson point processes with intensities $λ$ and $λ_e$, respectively.

Physical Layer Security: Channel Sounding Results for the Multi-Antenna Wiretap Channel
Entropy, 2023 Many physical-layer security works in the literature rely on purely theoretical work or simulated results to establish the value of physical-layer security in securing communications.
