英文摘要	an optical encryption method based on compressive ghost imaging (cgi) with double random-phase encoding (drpe), named drpe-cgi, is proposed. the information is first encrypted by the sender with drpe, the drpe-coded image is encrypted by the system of computational ghost imaging with a secret key. the key of n random-phase vectors is generated by the sender and will be shared with the receiver who is the authorized user. the receiver decrypts the drpe-coded image with the key, with the aid of cgi and a compressive sensing technique, and then reconstructs the original information by the technique of drpe-decoding. the experiments suggest that cryptanalysts cannot get any useful information about the original image even if they eavesdrop 60% of the key at a given time, so the security of drpe-cgi is higher than that of the security of conventional ghost imaging. furthermore, this method can reduce 40% of the information quantity compared with ghost imaging while the qualities of reconstructing the information are the same. it can also improve the quality of the reconstructed plaintext information compared with drpe-gi with the same sampling times. this technique can be immediately applied to encryption and data storage with the advantages of high security, fast transmission, and high quality of reconstructed information.
