Optical　encryption　based　on　interferenceless　coding　aperture　correlation　holography　(I-COACH)　is　one　of　the　holographic　encryption　technologies.　I-COACH　with　dual-channel　has　been　employed　to　encrypt　two　plaintexts,　not　only　is　the　encryption　capacity　limited,　but　when　the　two　plaintexts　are　horizontally　overlapped,　the　crosstalk　between　the　two　decrypted　plaintexts　becomes　significant.　To　address　these　issues,　we　present　an　optical　multiple　images　encryption　system　based　on　single-channel　I-COACH.　In　our　optical　encryption　system,　the　multiple　images　are　placed　adjacent　to　each　other　and　encrypted　simultaneously　through　a　single-shot　I-COACH.　The　traditional　cross-correlation　methods　fail　to　decrypt　the　multiple　plaintexts,　we　propose　a　decryption　scheme　based　on　a　novel　deep　learning　framework　(M-Net).　The　multiple　plaintexts　can　be　decrypted　from　a　single　ciphertext　simultaneously,　greatly　improving　the　decryption　efficiency　by　our　method.　Moreover,　the　crosstalk　between　the　multiple　images　is　avoided.　Various　experiments　are　conducted　to　demonstrate　the　effectiveness　and　feasibility　of　our　proposal.
