• Multiple-image encryption
• Optical security
• Phase retrieval
• Random-phase encoding

A novel technique for multiple-image optical encryption is proposed, in which a set of parallel plaintexts can be extracted from the same designed ciphertext respectively In the process of encryption. the principle of random phase encoding is utilized, and the phase keys corresponding to different plaintexts are achieved independently from the same designed ciphertext by cascade phase retrieval algorithm (CPRA) The advantages of the approach could be concluded as implementing decryption without cross-talk, infinite encrypted capacity and simple architecture.
