An Eavesdropping Model for Securing Communications over Wireless Broadcast Networks

Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 5

Abstract

 Wireless broadcast networks constitute one class of basic and important wireless networks, in which a source node simultaneously transmits a number of information messages to different destinations. However, broadcast communications make use of the open nature of the wireless medium, which presents a great challenge to achieve the secure communication for individual users. This is because information for all users is contained in one transmitted signal, and hence information destined for one user may be obtained by non- intended users unless special coding is used. In this paper, we study a broadcast network, in which a source node transmits confidential message flows to the user nodes, and each message flow is intended to be decoded accurately by one node while being kept secret from all other nodes. Nodes are thus considered to be eavesdroppers with regard to all other messages but their own. Here we consider two eavesdropping models. The first model is referred to as a collaborative eavesdropping model, in which the eavesdroppers can exchange their outputs to interpret the message. The second model is referred to as a non- collaborative eavesdropping model, in which eavesdroppers do not exchange their outputs.
