N2 - In this paper, we propose a cooperative secure transmission for a two-hop relay network with limited feedback. In the proposed scheme, the channel state information associated with cooperative users is quantized and limited bits are fed back for cooperative relay and jammer selection. By considering the quantization error introduced by the limited feedback, we investigate the performances of transmission outage probability and secrecy outage probability, and their closed-form expressions are derived. Based on these analytical results, we optimally design the target transmission rate and secrecy rate so that the average secrecy rate is maximized under the constraints of maximum permitted transmission outage probability and secrecy outage probability requirements. Simulation results are demonstrated to verify the analytical results for the proposed scheme, and demonstrate its secrecy performance improvement with light overhead.
