The secrecy capacity of practical quantum cryptography [PDF]
Quantum cryptography has attracted much recent attention due to its potential for providing secret communications that cannot be decrypted by any amount of computational effort. This is the first analysis of the secrecy of a practical implementation of the BB84 protocol that simultaneously takes into account and presents the {\it full} set of complete ...

Secure Communications in SWIPT-Enabled Two-Way Relay Networks
This paper investigates the secrecy performance of a wireless-powered two-way relay network in the presence of an eavesdropper. Based on adaptive time allocation (TA) and power splitting (PS), a novel secure relaying protocol is proposed. For the purpose

On the ergodic secrecy capacity with full duplex communication [PDF]
Full duplex communication promises performance gains in terms of the throughput and the delay. Generally, it has been shown that the throughput and delay gains of full duplex communication are somewhat limited in realistic network settings, leading researchers to study other possible applications of full duplex communication providing significantly ...

Secrecy Cognitive Gain of Cognitive Radio Sensor Networks with Primary Outage Constraint
This paper studies the physical layer security issue for cognitive radio sensor networks (CRSNs) with primary outage constraint, for which a tractable framework is developed to analyze the secrecy performance for CRSNs related to the random channel ...

Some New Results on the GaussianWiretap Feedback Channel
In this paper, the Gaussian wiretap feedback channel is revisited, and some new resultson its secrecy capacity are obtained. To be specific, first, we show that the Schalkwijk−Kailath (SK)feedback scheme, which achieves the secrecy capacity of the ...

Secrecy Capacity of Space Keying with Two Antennas [PDF]
Spatial modulation (SM) and space shift keying (SSK) use only one out of several transmit antennas at a time to transmit data via an antenna index. In such a system, the information is encoded by exploiting channel randomness i.e. the fact that channels between different transmit and receive antennas are random.

Robust Biometric Authentication from an Information Theoretic Perspective
Robust biometric authentication is studied from an information theoretic perspective. Compound sources are used to account for uncertainty in the knowledge of the source statistics and are further used to model certain attack classes.
