abstract the contact between major settlements in the central plateau of iran, especially in desert areas, was not possible without having a secure communication system. in this regard, designing communication networks through constructing secure roads with halfway caravansarais in desert areas, usually without secure underground and surface water supply, needed special insights and provisions....

Wireless LANs based on the IEEE 802.11 technology are becoming increasingly prevalent. The availability of highbandwidth together with the convenience of being a wireless medium makes it a compelling technology for multimediabased applications. In this paper, we present a gatewaybased architecture of the wireless home media network and develop a secure registration protocol that is appropriate ...

The role of multiple antennas for secure communication is investigated within the framework of Wyner’s wiretap channel. We characterize the secrecy capacity in terms of generalized eigenvalues when the sender and eavesdropper have multiple antennas, the intended receiver has a single antenna, and the channel matrices are fixed and known to all the terminals, and show that a beamforming strategy...

This book gives an introduction to group key management protocols in different network settings. It can be recommended to early researchers in the areas of group key management, secure multicast and secure communication in sensor networks. The book discusses various security issues in group communications in a network-aware approach. However, it fails to show how to rigorously analyze group key...

Abstract—This work considers load-balance control among the relays under the secure transmission protocol via relay cooperation in two-hop wireless networks without the information of both eavesdropper channels and locations. The available two-hop secure transmission protocols in physical layer secrecy framework cannot provide a flexible load-balance control, which may significantly limit their...

In this paper, we propose a polar coding scheme for secure communication over the multiple-input, single-output, single-antenna eavesdropper (MISOSE) fading channel. We consider the case of block fading channels with known eavesdropper channel state information (CSI) and the case of fading channels with known eavesdropper channel distribution information (CDI). We use the artificial noise assis...

In this study, we propose a secure communication scheme based on the synchronization of two identical fractional-order chaotic systems. The fractional-order derivative is in Caputo sense, and for synchronization, we use a robust sliding-mode control scheme. The designed sliding surface is taken simply due to using special technic for fractional-order systems. Also, unlike most manuscripts, the ...
