Abstract

In this paper, we consider the problem of transmission of sensitive message in wireless multicast cellular network through identically distributed Nakagami-m fading multiple-input multiple-output (MIMO) channels considering the existence of multiple eavesdroppers. It is assumed that the antennas in the destinations and eavesdroppers are exponentially correlated. Considering channel state information (CSI) at the receiver, the closed-form analytical expressions for the ergodic secrecy multicast capacity (ESMC) and the probability of non zero secrecy multicast capacity (PNSMC) have been derived to investigate the effect of correlation and fading parameter on the proposed model. Numerical results of the derived analytical expressions are presented and demonstrated using Monte-Carlo simulation.

On the Secrecy Mutual Information of Nakagami-m Fading SIMO Channel

M. Z. I. Sarkar, Tharmalingam Ratnarajah

In this paper, we consider the transmission of confidential message through non-identically and identically independent Nakagami-m fading single-input multiple-output (SIMO) channel in the presence of an eavesdropper. We are interested in protecting this message against eavesdropping i.e. the information is secure if it cannot be eavesdropped by any eavesdropper. Based on the problem of secure communications between transmitter and intended receiver over Nakagami-m fading channel where an eavesdropper observes their transmissions through another Nakagami-m fading channel, we derive the analytical expressions for the probability of non-zero secrecy mutual information, secure outage probability and ergodic secrecy mutual information of SIMO wireless communication systems over non-identically and identically independent Nakagami-m fading subchannels. Numerical results are presented and verified via Monte-Carlo simulation.

Secure wireless multicasting through Nakagami-m fading MISO channel

Md. Zahurul I. Sarkar, Tharmalingam Ratnarajah

In the group-oriented applications such as military and commercial wireless cellular networks often require the same data to be conveyed to multiple users simultaneously. This technique is usually referred to as physical layer multicasting. In this paper, we consider the problem of secret communication over Nakagami-m fading multiple-input single-output (MISO) channel, where a single transmitter sends a common and confidential message to a group of receivers in the presence of an eavesdropper. We are interested in protecting this message from eavesdropping. At first, we define the secrecy multicast capacity for a K-receiver multicast channel at which the eavesdropper is unable to decode any information from the multicast channels and find the analytical expression for the lower bound of average secrecy multicast capacity. Then, we define the secrecy multicast capacity in terms of secure outage probability, and find the analytical expressions for the probability of non-zero secrecy multicast capacity and secure outage probability to study the outage behavior of the proposed model.

Analysis of Secrecy Performance over Correlated η - µ Fading Channels

In a multiple antenna network, correlation among the antennas tends to reduce the system capacity. In this paper, the effect of correlation on the secrecy performance over η - μ fading channel has been analyzed considering a multicast network in the presence of multiple eavesdroppers. Simple closed-form analytical expressions of the ergodic secrecy multicast capacity and the secure outage probability for multicasting are derived to numerically quantify the effect of correlation. The consequence of changing the number of receiving antennas on correlation has been observed and the secrecy performance of some commonly used channels like Gaussian channel, Rayleigh and Nakagami- m fading channels which can be found as a special case of the η - μ fading channel, have also been investigated. The derived expressions are finally verified through 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.

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.

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.
