Abstract

This Paper presents a comprehensive analysis of secrecy performance in a multicast wireless communication network operating over Nakagami- 0.5 fading channels. The Probability of non-zero secrecy multicast capacity (PNSMC) and the secure outage probability for multicasting (SOPM) are analytically developed under the influence of multiple relays, legitimate users, and eavesdroppers. To ensure enhanced secrecy reliability, an opportunistic relay selection approach is integrated with selection combining (SC) diversity at the destination. Verified the analytical results through extensive Monte Carlo simulations, exhibiting a strong correspondence with theoretical predictions. Numerical evaluations indicate that an increased number of relays and destination antennas notably strengthen secrecy performance, whereas stronger eavesdropper channels deteriorate it. In general, the framework presented provides useful design guidelines for cooperative secure multicast communication systems operating in severe fading environments.

Secure Wireless Multicasting through Nakagami-m Fading Channels with Multi-Hop Relaying

Md Mizanur Rahman, Md. Zahurul I. Sarkar, Mohammad Mahmud Hasan

The additional diversity gain provided by the relays improves the secrecy capacity of communications system significantly. The multiple hops in the relaying system is an important technique to improve this diversity gain. The development of an analytical mathematical model of ensuring security in multicasting through fading channels incorporating this benefit of multi-hop relaying is still an open problem. Motivated by this issue, this paper considers a secure wireless multicasting scenario employing multi-hop relaying technique over frequency selective Nakagami-m fading channel and develops an analytical mathematical model to ensure the security against multiple eavesdroppers. This mathematical model has been developed based on the closed-form analytical expressions of the probability of non-zero secrecy multicast capacity (PNSMC) and the secure outage probability for multicasting (SOPM) to ensure the security in the presence of multiple eavesdroppers. Moreover, the effects of the fading parameter of multicast channel, the number of hops and eavesdropper are investigated. The results show that the security in multicasting through Nakagami-m fading channel with multi-hop relaying system is more sensitive to the number of hops and eavesdroppers. The fading of multicast channel helps to improve the secrecy multicast capacity and is not the enemy of security in multicasting.

Mahmudul Hasan, M. Z. I. Sarkar, A. Z. Rizve +1 more

This paper focuses on a secure wireless multicasting under the employment of generalized receiver along with selection combining (SC) diversity and opportunistic relaying technique. SC diversity technique mitigate the fading effect significantly. Opportunistic relaying gives cooperative gain by selecting the relay with highest signal to noise ratio (SNR) and the generalized receiver is flexible to adaptive signal processing. In this paper the transmitted signal has been protected from eavesdropping by means of the effect of quantity of relay, receive side antenna number, eavesdropper side antenna number, quantity of multicast user and quantity of eavesdropper. In this manner the authors derived the closed form analytical expression for probability of non-zero secrecy multicast capacity (PNSMC) and secure outage probability for multicasting (SOPM) with the consideration that, multiple eavesdroppers are present. 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 SC diversity and opportunistic relaying technique is significantly affected by the number of relay, transmit and receive side antenna number, number of multicast user and number of eavesdropper, specially at low noise power region of eavesdropper.

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.

Opportunistic Relaying Technique over Rayleigh Fading Channel to Improve Multicast Security

Md. Shamim Hossain, Md. Zahurul I. Sarkar

The performance of Rayleigh fading channels is substantially impacted by the impacts of relays, antennas, and the number of branches. Opportunistic relaying is a potent technique for enhancing the effects of the aforementioned factors while enhancing the performance of fading channels. Due to these issues, a secure wireless multicasting scenario using opportunistic relaying over Rayleigh fading channel in the presence of multiple wiretappers is taken into consideration in this study. So the investigation of a secure wireless multicasting scenario using opportunistic relaying over Rayleigh fading channel in the presence of multiple wiretappers is the focus of this paper. The primary goals of this study are to maximize security in wireless multicasting while minimizing security loss caused by the effects of relays, branches at destinations and wiretappers, as well as multicast users and wiretappers through opportunistic relaying. To comprehend the insight effects of prior parameters, the closed form analytical expressions are constructed for the probability of non-zero secrecy multicast capacity (PNSMC), ergodic secrecy multicast capacity (ESMC), and secure outage probability for multicasting (SOPM). The findings demonstrate that opportunistic relaying is a successful method for reducing the loss of security in multicasting.

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.

Secrecy Analysis of Correlated Multicast Channel with Equal Gain Combining and Cooperative Relaying

Sarjana Shabab, Md. Zahurul I. Sarkar

Wireless communication security is critical for next-generation high-yield systems such as 5G and 6G. Traditional multicasting protocols often lack a robust framework to ensure proper authentication and privacy, with correlation degrading signal-to-noise ratio (SNR) and reducing overall channel capacity. To increase security, equal gain combining (EGC), one of the diversity-combining techniques mitigates fading and correlation, whereas cooperative relaying chooses the relay with the highest SNR to optimize performance. This paper investigates the combined use of EGC and cooperative relaying to strengthen multicast security. Closed-form expressions for secure outage probability (SOPM) and non-zero secrecy multicast capacity (PNSMC) are derived, considering fading, correlation, and relay diversity. Results show that security improves with stronger fading, more destination antennas, and additional relays, and is adversely affected by increased signal correlation and a higher number of eavesdroppers.
