Improving Wireless Security for Bi-Directional Communication Scenarios

In this paper, the authors study how to improve wireless security for bi-directional communications. For the scenario with single-antenna nodes, effective criteria for relay and jamming node selection are developed to ensure that the probability to have non-zero secrecy rates is approaching to one given sufficient relays. For the scenario with multiple-antenna nodes, effective pre-coding is proposed to ensure that the mutual information obtained at the eavesdropper decreases to zero when there is a sufficient number of relays.
