A Closed-Form Expression for Outage Secrecy Capacity in Wireless Information-Theoretic Security

چکیده
This paper provides a closed-form expression for Outage Secrecy Capacity in Wireless Information-Theoretic Security. This is accomplished on the basis of an approximation of the exponential function via a first-order Taylor series. The error of this method is calculated for two different channel cases, and the resulting precision confirms the correctness of this approach. Thus, the Outage Secrecy Capacity can be calculated for a given Outage Probability and for a given propagation environment (path loss exponent, average main channel SNR), allowing us to estimate with increased precision the boundaries of secure communications.

The inherent openness of wireless medium makes information security one of the most important and difficult problems in wireless networks. Physical layer security, which achieves the information-theoretic security by exploiting the differences between the physical properties of signal channels such that a degraded signal at an eavesdropper is always ensured and thus the original data can be har...

In this paper, the information-theoretic secrecy for the log-normal fading channel is investigated. In particular, the closed-form expressions of the probability of strictly positive secrecy capacity are derived for two wireless communication systems, with single eavesdropper and double eavesdroppers, respectively. Keywords-Information-theoretic secrecy, log-normal fading, secrecy capacity.

In this paper, we study physical layer security (PLS) of wireless networks in presence of one eavesdropper. Assume that the channel state information (CSI) of the eavesdropper cannot be obtained at the transmitter, such as CSI can be then estimated through the CSI of a torch node. In addition, a practical issue of wireless nodes, i.e., hardware impairment (HI), is considered at the source node ...

We investigate the secure communications over correlated wiretap Rayleigh fading channels assuming the full channel state information (CSI) available. Based on the information theoretic formulation, we derive closed-form expressions for the average secrecy capacity and the outage probability. Simulation results confirm our analytical expressions.

In this two-part paper, we consider the transmission of confidential data over wireless wiretap channels. The first part presents an information-theoretic problem formulation in which two legitimate partners communicate over a quasi-static fading channel and an eavesdropper observes their transmissions through another independent quasi-static fading channel. We define the secrecy capacity in te...
