In this work, the authors consider the security performance for the mixed radio frequency link and visible‐light link cooperative relaying system, where the relay has the energy collection ability and can extract the direct current part existing in the visible‐light signal. Then, the relay uses the collected energy to demodulate the received visible‐light signal and retransmit it through the radio frequency link. With this equipment, some analytical expressions of the average secrecy capacity and the secrecy outage probability are derived. Furthermore, the asymptotic expression is also derived to examine the influence of the various configuration parameters on the secrecy performance of the mixed relaying system. At last, some numerical and simulation results are given to verify the theoretical analysis.
