In this paper, an asymmetric multiple-image encryption algorithm based on compressed sensing and cylindrical diffraction is proposed. Firstly, these multiple gray scale images are compressed by compressed sensing in separately. Then single amplitude ciphertext is obtained by asymmetric operation of phase truncation after cylindrical diffraction. This method not only can achieve multiple-image encryption with a small amount of data, but also can prevent information disclosure. Moreover, the proposed method has high security because it can resist the phase-retrieval attack. Numerical simulations have demonstrated the security and effectiveness of the proposed method.
