Abstract

Recently, there has been a growing interest in applying multiple antennas to achieve information-theoretic security in wireless communication networks. In this paper, we consider the transmission of common confidential data from a single-antenna transmitter to multiple multi-antenna receivers in the presence of multiple multi-antenna eavesdroppers. Both the receivers and eavesdroppers employ maximal-ratio combining (MRC) to combine the signals received at multiple antennas. For the considered system, we derive its connection outage probability and secrecy outage probability to characterize the reliability level and the security level, respectively. Numerical results are also provided to analyze the tradeoff among the reliability and security performances and the number of antennas (or nodes) of either receivers or eavesdroppers.

Secrecy Performance of Multicasting Networks Over Nakagami-0.5 Fading Channels Employing MRC Diversity

Abdullah Al-Faruk, Sadia Tanzim Islam, Md. Shadman Rafid Khan +3 more

This paper investigates the role of the Maximum Ratio Combining (MRC) diversity scheme in enhancing security for multicast communications over a Nakagami-0.5 fading channel in the presence of multiple eavesdroppers. The considered scenario involves a singleantenna transmitter communicating confidentially with multiple legitimate receivers, while multiple eavesdroppers attempt to intercept the transmission. Explicit mathematical formulation have been established to evaluate the likelihood of achieving a positive secrecy multicast capacity and the probability of a secure outage, providing a theoretical framework to evaluate the secrecy performance. The analysis highlights the impact of critical system parameters, including the number of legitimate receivers, the number of eavesdroppers and the number of antennas employed at both legitimate receivers and eavesdroppers. By employing MRC, which coherently combines signals from multiple antennas to maximize the received signal-to-noise ratio, the study demonstrates significant improvements in the secrecy performance of multicast systems. The findings contribute valuable insights into designing more secure multicast communication networks in the presence of severe fading and adversarial interception.

On Wireless Channels with M-Antenna Eavesdroppers: Characterization of the Outage Probability and Outage Secrecy Capacity

Vinay Uday Prabhu, Miguel R. D. Rodrigues

In this paper, we consider secure communications between a single antenna transmitter and a single antenna receiver in the presence of a multiple antenna eavesdropper employing MRC or SDC reception. We show that an M-antenna eavesdropper performing SDC reception has precisely the same degrading effect on secrecy as M single antenna eavesdroppers under independent fading conditions. We also show that an M-antenna eavesdropper performing MRC reception causes greater secrecy degradation than an M-antenna eavesdropper performing SDC reception or M single antenna eavesdroppers. We also derive closed-form expressions for the asymptotic high SNR outage secrecy capacity for both the MRC and the SDC eavesdropper cases. Various numerical results are presented that corroborate the analysis.

Adaptive Secure Rate Allocation via TAS/MRC under Multi-Antenna Eavesdroppers

Irfan Muhammad, Onel L. Alcaraz López, Hirley Alves +3 more

This paper investigates the secrecy outage performance of a multiple-input multiple-output and multi-antenna eavesdropper system. We consider a novel formulation for the secrecy outage probability, which is capable of quantifying reliability and secrecy separately, thus constituting a useful tool in the context of new scenarios with stringent requirements on reliability as the case of ultra-reliable low-latency communication. Our system considers a multi-antenna transmitter, Alice, that employs transmit antenna selection, a legitimate multi-antenna receiver, Bob, and a multi-antenna eavesdropper, Eve, where both employing maximal-ratio combining. For this system, exact and simpler asymptotic closed-form expressions for the conditional outage probability are provided. Moreover, for the case where channel state information is available at the three nodes, a numerical secure throughput maximization is carried out by considering quality-of-service and security constraints for an adaptive rate allocation scheme in an ON-OFF transmission. Our proposed closed-form expressions are validated via Monte Carlo simulations.

Joint effect of jamming and noise in wiretap channels with multiple antennas

Yosbel R. Ortega, Prabhat K. Upadhyay, Daniel Benevides da Costa +4 more

In this paper, the joint effect of multiple jamming signals and noise at the eavesdropper in wiretap channels is studied in terms of the secrecy outage probability, where all nodes are deployed with multiple antennas. Specifically, the transmitter employs a transmit antenna selection (TAS) technique; the legitimate receiver uses either a selection combining (SC) or a maximal-ratio combining (MRC) scheme; and the eavesdropper adopts the MRC technique. Exact closed-form expressions for the secrecy outage probability are derived for both SC and MRC schemes at the legitimate receiver, which are applicable for arbitrary number of power distributed jamming signals. An asymptotic secrecy outage analysis is conducted, which shows that the diversity gains for all combining schemes equal to the product of the number of antennas at the transmitter and the legitimate receiver. Representative numerical examples are presented to illustrate the effects of the key system parameters on the secrecy outage performance. Finally, the proposed analysis is validated through Monte Carlo simulation results.

Enhancing Security in Multicasting Employing Neyman-Pearson Receiver with MRC Diversity and Opportunistic Relaying Techniques

A. Z. Rizve, M. N. M. Rahi, S. S. Gupta +3 more

This paper presents a study on secure wireless multicasting using a Neyman-Pearson receiver in conjunction with the maximal ratio combining (MRC) diversity technique and opportunistic relaying. The MRC diversity technique effectively mitigates the impact of fading, while opportunistic relaying enhances cooperative communication by selecting the relay with the highest signal-to-noise ratio (SNR). The authors aim to safeguard the transmitted signal from eavesdropping, considering factors such as the number of relays, the number of receive and eavesdropper-side antennas, the number of multicast users, and the number of eavesdroppers. In this context, closed-form analytical expressions are derived for the probability of nonzero secrecy multicast capacity (PNSMC) and the secure outage probability for multicasting (SOPM) to ensure secrecy in the presence of multiple eavesdroppers. These mathematical models shed essential light on how the previously listed parameters affect things. Numerical results demonstrate that the security of the multicast network employing the Neyman-Pearson receiver, MRC diversity, and opportunistic relaying is significantly influenced by the number of relays, antennas on both the receiver and eavesdropper sides, multicast users, and eavesdroppers, particularly in low noise power regions of the eavesdropper channel.

This paper focuses on a secure wireless multicas-ting under the employment of generalized receiver along with maximal ratio combining (MRC) diversity technique. MRC diversity technique mitigate the fading effect significantly and the generalized receiver is flexible to adaptive signal processing. In this paper, the transmitted signal has been protected from eavesdropping considering the effect of receive side antenna number, eavesdropper side antenna number, multicast user number and eavesdropper number. In this manner the authors derived the closed form analytical expression for the probability of non-zero secrecy capacity of multicast system (PNSMC) and for the secure outage probability of multicast system (SOPM) to ensure the secrecy in the presence of multiple eavesdroppers. These mathematical models are helpful to realize the insight of the effects of aforementioned parameters. The numerical results show that, security in multicast network employing generalized receiver with MRC diversity technique is significantly affected by the number of receive antenna, eavesdropper antenna, multicast user and eavesdropper, specially at low noise power region of eavesdropper.
