Aiming at the security problem of energy-constrained devices in wireless communication, a time reversal (TR) and artificial noise wireless cooperative energy transmission scheme is proposed to improve the security performance of the energy-constrained wireless power supply network. The scheme uses the TR technology at multi-antenna sources, makes use of the time and space focusing of the TR technology to focus the wireless signal to the destination and increases the wireless energy collection. In addition, the energy collection and self-jamming artificial noise operation are used in energy-constrained destinations to prolong the service life of the equipment and confuse eavesdroppers. Finally, the Lyapunov algorithm is used to optimize the time allocation factor. The transmission power of sub, sender and self-interference artificial noise makes the secret rate reach the maximum. The theoretical analysis and simulations prove the energy efficiency and confidentiality of the proposed scheme.
