Abstract

This work deals with the development of a mathematical model consisting of the closed form analytical expressions (CFAEs) of the measures which ensures the security in α - μ fading multicast channels. Authors are interested to ensure that no eavesdropper can wiretap any data from the system. Two important secrecy measures namely probability of non-zero secrecy multicast capacity (PNSMC) and the secure outage probability of multicasting (SOPM) are considered to inquire the insight of this proposed work. Results show that the performance analysis of α - μ fading channel includes the performance of Gaussian, Exponential, Rayleigh, Weibull, Gamma, Nakagami-m etc. distributions. So, the generalization of security analysis in fading channels is mostly achieved by the performance evaluation of α - μ fading channel. Finally, the authenticity of analytical outcomes are checked by the Monte-Carlo simulation.

Secure Wireless Multicasting over α-η-µ Fading Channel

Shanmuga Priya, Milton Kumar Kundu, Zerin Nusrat +2 more

As the variation of the fading signal can be modeled at a very small scale using α-η-μ fading channel, this paper concentrates on the security performance analysis over the α-η-μ fading multicast channel considering the presence of multiple eavesdroppers. The performance metrics of probability of nonzero secrecy multicast capacity (PNSMC) and secure outage probability for multicasting (SOPM)) for this channel has been analyzed in this work. The effect of the number of receivers, eavesdroppers and total amount of atmospheric fading on the secrecy performance have also been presented by the authors. The results show tremendous improvement in secrecy performance for higher values of fading parameter and smaller number of receivers, and eavesdropper. Finally, verification of the derived closed form expressions (CFEs) for PNSMC and SOPM has been done through Monte-Carlo simulations.

Enhancing Security in Wireless Multicasting over k - µ Fading Channel

A. S. M. Badrudduza, Milton Kumar Kundu

In this paper, a secure wireless multicast network over k - μ fading channel is considered, where a source transmits secret information to a group of receivers. A group of eavesdroppers are also present in the network which are responsible for wiretapping the transmitted information. A perfect secrecy can be obtained if the eavesdroppers are not able to decode any information from the source. In order to investigate the secrecy capacity of the multicast network, at first a novel expression for Ergodic secrecy multicast capacity is derived in closed-form. The outage performance of the proposed network is analyzed obtaining the closed-form expressions of secure outage probability for multicasting. The effects of fading is determined and a beneficent insight is provided into investigating the secrecy performance of some other common fading scenarios such as Rician, Rayleigh, Nakagami-m, Gaussian etc. using the derived novel expressions of this paper. Monte-Carlo simulations are performed to validate the derived analytical expressions.

Secrecy Performance Analysis over Inverse Gamma Composite Multicast Fading Channels

Abdulkarim Al Hanif, A. S. M. Badrudduza, Md. Shakhawat Hossen +2 more

Secrecy performance of realistic wireless multicast scenarios are significantly deteriorated by simultaneous occurrence of multipath and shadowing which are modeled using composite fading channels. To resolve this security threat, in this paper a framework is proposed where a source transmits private multicast messages to multiple receivers over η - μ / inverse gamma composite fading channels. A group of eavesdroppers are trying to overhear this secret communication. Perfect secrecy is obtained if eavesdropper can not decode any information from the multicast links. Secrecy analysis is carried out deriving closed-form expressions of two well-known secrecy measures i.e. probability of non-zero secrecy capacity and secure outage probability for multicasting. The impacts of multipath, shadowing and other system parameters on the outage performance of the proposed scenario are quantified using the derived expressions. A generic nature of η - μ / inverse gamma distribution is obtained by showing Rayleigh, Nakagami-m, Nakagami-q, η - μ fading and Gaussian channels as a special case of this distribution. Finally, Monte-Carlo simulations are presented to verify the derived expressions.

Enhancement of Physical Layer Security over Generalized Nakagami-mmm Fading Multicast Channel

Sarjana Shabab, A. S. M. Badrudduza, Milton Kumar Kundu

Multicasting over wireless channels is a challenging task now-a-days as conventional frameworks can not ensure the secrecy of transmitted information. Hence, in this paper, a secure multicast framework is presented over Generalized Nakagami-m fading channel in the appearance of multiple eavesdroppers and key concentration is given to the transmission of information at a secrecy rate so that no eavesdropper can decode any information from the multicast channels. The impact of the system parameters on the secrecy performance of proposed system is analyzed by obtaining closed-from mathematical expressions of some secrecy measures such as probability of nonzero secrecy multicast capacity and secure outage probability for multicasting. The generalization of the proposed model is achieved by obtaining Rayleigh, Nakagami- m, Gamma, Half-normal, Weibull, Exponential, etc. fading channels as a special case of Generalized Nakagami- m fading channel. Finally, the correctness of the derived expressions is authorized using Monte-Carlo simulations.

Impact of Correlation on the Security in Multicasting through κ - µ Shadowed Fading Channels

Md. Najib Ibrahim, M. Z. I. Sarkar, A. S. M. Badrudduza +2 more

This paper focuse on the secrecy performance analysis over correlated κ - μ shadowed fading multicast channels considering a single input multiple output (SIMO) scenario. The proposed network consists of a single antenna source, and multiple receivers and eavesdroppers which are equipped with multiple antennas. The security analysis has been performed by developing a mathematical model and deriving the novel closed-form expressions(CFEs)of the performance matrices such as probability of non-zero secrecy multicast capacity (PNSMC) and secure outage probability for multicasting (SOPM). The secrecy capacity and outage characteristics of the multicast network has been investigated for the simultaneous presence of correlation and shadowing and it is observed that impact of each system parameter can be evaluated perfectly using the derived expressions. Finally, the analytical results has been verified by Monte-Carlo Simulations.

Security Against Multiple Eavesdroppers for Multicasting Over Nakagami-q Fading Channel

Abida Sultana Sumona, Milton Kumar Kundu, A. S. M. Badrudduza +1 more

A confidential multicasting scenario is considered through Nakagami-q fading channels in the presence of multiple eavesdroppers. We are interested to protect the confidential information so that no eavesdropper can decode any information from the multicast channels. A mathematical model is developed which consists of the closed-form analytical expressions for the ergodic secrecy multicast capacity and the secure outage probability for multicasting to ensure this security. Some numerical results are shown to justify the validity of the developed mathematical model. Moreover, the analytical expressions are verified via Monte-Carlo simulation.
