Abstract In this paper, according to the phase object in the ghost imaging has a stealth effect, we proposed an optical encryption method based on compressive ghost imaging and public key cryptography. This method solves the key distribution problem of ghost imaging encryption, and reduces the additional cost of establishing security channels. The simulation results verify the feasibility, security and robustness of the proposed encryption scheme. This technique can be immediately applied to encryption and data storage with the advantages of high-safety, high-robustness and low-cost.
