Summary This work investigates the security of optical ciphers integrating compressed sensing (CS) with double random phase encoding. Theoretical analysis demonstrates that the combined system, regardless of the implementation order of the two procedures, can be normalized as a single CS projection process, whose equivalent measurement matrix can be recovered by plaintext attack. The proved restricted isometry property of the equivalent measurement matrices further renders the adversary great convenience to recover the plaintext with only a single-step ℓ1 optimization. Computer simulations are also carried out for verification.
