Abstract

In this paper, a single-input multiple-output (SIMO) simultaneous wireless information and power transfer system consisting of one base station, one desired information receiver and N (N > 1) energy-harvesting receivers is considered. Each link in the considered system suffers not only from small-scale fading but also path-loss. In particular, we focus on the physical layer security performance including secrecy outage and secrecy capacity in the presence of eavesdroppers. We derive the closed-form analytical expression for the exact and the asymptotic secrecy outage probability while considering each eavesdropping link experiences independent but not necessarily identical Rayleigh fading. The closed-form analytical expression for the average secrecy capacity has also been derived for the case that all eavesdropping links experience independent and identical Rayleigh fading. Numerical and Monte Carlo simulation results are presented to verify our derived analytical models.

On secrecy outage of MISO SWIPT systems in the presence of imperfect CSI

Gaofeng Pan, Hongjiang Lei, Yansha Deng +3 more

In this work, a multiple-input single-output (MISO) simultaneous wireless information and power transfer (SWIPT) system including one base station (BS) equipped with multiple antennas, one desired single-antenna information receiver (IR) and N (N > 1) single-antenna energy-harvesting receivers (ERs) is considered. By considering that the information signal of the desired IR may be eavesdropped by ERs if ERs are malicious, we investigate the secrecy performance of the target MISO SWIPT system when imperfect channel state information (CSI) is available and adopted for transmit antenna selection at the BS. Considering that each eavesdropping link experiences independent not necessarily identically distributed Rayleigh fading, the closed-form expressions for the exact and the asymptotic secrecy outage probability are derived and verified by simulation results.

On Secrecy Performance of MISO SWIPT Systems With TAS and Imperfect CSI

In this paper, a multiple-input single-output (MISO) simultaneous wireless information and power transfer (SWIPT) system, including one base station (BS) equipped with multiple antennas, one desired single-antenna information receiver (IR), and N (N > 1) single-antenna energy-harvesting receivers (ERs) is considered. Assuming that the information signal to the desired IR may be eavesdropped by ERs if ERs are malicious, we investigate the secrecy performance of the target MISO SWIPT system when imperfect channel state information (CSI) is available and adopted for transmit antenna selection at the BS. Considering that each eavesdropping link experiences independent but not necessarily identically distributed Rayleigh fading, the closed-form expressions for the exact and the asymptotic secrecy outage probability, and the average secrecy capacity are derived and verified by simulations. Furthermore, the optimal power splitting factor is derived for each ER to realize the tradeoff between the energy harvesting and the information eavesdropping. Our results reveal the impact of the imperfect CSI on the secrecy performance of MISO SWIPT systems in the presence of multiple wiretap channels.

Average Secrecy Capacity Performance Analysis for SWIPT-Based SIMO Underlay Cognitive Radio

Mohammad Javad Saber, Seyedeh Maryam Mazloum, Seyed Mohammad Sajad Sadough

We address the physical layer security (PHY-security) for an underlay single-input multiple-output (SIMO) cognitive radio network using simultaneous wireless information and power transfer (SWIPT). The considered system model is composed of one primary receiver, one secondary transceiver, and one energy harvesting receiver that may potentially be an eavesdropper. First, the closed-form analytic expression of the average secrecy capacity (ASC) of the considered network is derived. Second, we analyze the network's achievable ASC under Rayleigh fading assumption for all underlying channels. Our results indicate that ASC performance is improved by reducing the number of deployed antennas at the energy receiver or by increasing the number of antennas deployed at the information receiver.

Secrecy performance analysis of energy harvesting wireless networks with multiple power transfer stations and destinations in the presence of multiple eavesdroppers

Tien‐Vu Truong, Nguyen‐Son Vo, Dac‐Binh Ha +1 more

Nowadays, physical layer secrecy has become the new approach to enhance information security of wireless networks and have attracted the attention of lot of researchers in the world. This paper investigates the physical layer secrecy performance of radio frequency energy harvesting (RF-EH) networks over Rayleigh fading channels. The considered RF-EH system consists of multiple power transfer stations, one source and multiple destinations in the presence of multiple passive eavesdroppers. The best power transfer station and the best received signal at destination is selected among multiple power transfer stations and among multiple destinations respectively. By using statistical characteristics of the signal-to-noise ratio (SNR), the exact closed-form expressions of existence probability of secrecy capacity and secrecy outage probability are derived. Finally, simulation results confirm an agreement between our analysis and equivalent Monte-Carlo simulations.

Secrecy performance analysis of single-input multiple-output generalized-K fading channels

Hongjiang Lei, Imran Shafique Ansari, Chao Gao +3 more

In this paper, the transmission of confidential messages through single-input multiple-output (SIMO) independent and identically generalized- K ( K G ) fading channels is considered, where the eavesdropper overhears the transmission from the transmitter to the receiver. Both the receiver and the eavesdropper are equipped with multiple antennas, and both active and passive eavesdroppings are considered where the channel state information of the eavesdropper’s channel is or is not available at the transmitter. The secrecy performance of SIMO K G systems is investigated. Analytical expressions for secrecy outage probability and average secrecy capacity of SIMO systems are derived via two different methods, in which K G distribution is approximated by the Gamma and mixture Gamma distributions, respectively. Numerical results are presented and verified via the Monte-Carlo simulation.

On the Secrecy Performance of SWIPT Receiver Architectures with Multiple Eavesdroppers

Furqan Jameel, Shurjeel Wyne, Syed Junaid Nawaz +2 more

Physical layer security (PLS) has been shown to hold promise as a new paradigm for securing wireless links. In contrast with the conventional cryptographic techniques, PLS methods exploit the random fading in wireless channels to provide link security. As the channel dynamics prevent a constant rate of secure communications between the legitimate terminals, the outage probability of the achievable secrecy rate is used as a measure of the secrecy performance. This work investigates the secrecy outage probability of a simultaneous wireless information and power transfer (SWIPT) system, which operates in the presence of multiple eavesdroppers that also have the energy harvesting capability. The loss in secrecy performance due to eavesdropper collusion, i.e., information sharing between the eavesdroppers to decode the secret message, is also analyzed. We derive closed‐form expressions for the secrecy outage probability for Nakagami‐m fading on the links and imperfect channel estimation at the receivers. Our analysis considers different combinations of the separated and the integrated SWIPT receiver architectures at the receivers. Numerical results are provided to validate our analysis.
