We investigate the problem of eavesdropping control in wireless communications networks. When a confidential message is transmitted through a wireless network, there is a potential security breach or 'information leakage' due to the network's susceptibility to eavesdropping. In this work, we quantify the information leakage problem in the context of resource allocation. By limiting the signal to interference...
Wireless communication is particularly susceptible to eavesdropping due to its broadcast nature. Security and privacy systems have become critical for wireless providers and enterprise networks. This paper considers the problem of secret communication over the Gaussian broadcast channel, where a multiple-antenna transmitter wishes to send independent confidential messages to two users with information-theoretic...
A secure wireless broadcast network model is investigated, in which a source node broadcasts K confidential message flows to N user nodes, with each message intended to be decoded accurately by one user and to be kept secret from all of other users (who are thus considered to be eavesdroppers with regard to all other messages but their own). The source maintains a queue for each message flow if it...
