Secure wireless multicasting through Nakagami-m fading MISO channel

Abstract

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.

On the secure outage performance for wireless multicasting through slow fading channels

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 are interested in protecting these data from eavesdropping. Here, we consider the transmission of confidential data through slow fading channels in the presence of single as well as multiple eavesdroppers. We define the perfect secrecy multicast mutual information in terms of secure outage probability for three different scenarios of secure wireless multicasting and provide a complete characterization of the maximum transmission rate at which the eavesdropper/eavesdroppers is/are unable to decode any information. We also present the average secrecy mutual information for multicasting in the presence of multiple eavesdroppers.

Secure Communication through Nakagami-m Fading MISO Channel

Md. Zahurul I. Sarkar, Tharmalingam Ratnarajah

We consider the problem of secret communication over Nakagami-m fading multiple-input single-output (MISO) broadcast channel, where transmitter sends messages to the destination users following two different transmission protocols. In the first transmission protocol, transmitter sends a confidential message to user 1, and user 2 acts as an eavesdropper. In this protocol, at first, we define the ergodic secrecy capacity for the full channel state information (CSI) case and then we consider the case of only main channel CSI at the transmitter. Finally, we define the secrecy capacity in case of open-loop spatial multiplexing transmission scheme and present the analytical expression for the lower bound of ergodic secrecy capacity. In the second transmission protocol, we consider the transmission of two independent messages to user 1 and user 2 with information-theoretic secrecy, where each user would like to obtain its own confidential message in a reliable and safe manner. Under this communication scenario, an achievable secrecy capacity region is developed using secret dirty-paper coding scheme.

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.

Information-theoretic security in wireless multicasting

Md. Zahurul I. Sarkar, Tharmalingam Ratnarajah

In this paper, a wireless multicast scenario is considered in which the transmitter sends a common message to a group of client receivers through quasi-static Rayleigh fading channel in the presence of an eavesdropper. The communication between transmitter and each client receiver is said to be secured if the eavesdropper is unable to decode any information. On the basis of an information-theoretic formulation of the confidential communications between transmitter and a group of client receivers, we define the expected secrecy sum-mutual information in terms of secure outage probability and provide a complete characterization of maximum transmission rate at which the eavesdropper is unable to decode any information. Moreover, we find the probability of non-zero secrecy mutual information and present an analytical expression for ergodic secrecy multicast mutual information of the proposed model.

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.

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

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.
