Asymmetric optical cryptosystem based on coherent superposition and equal modulus decomposition: comment

Abstract

I comment on the recent Letter by Cai et al. [Opt. Lett.40, 475 (2015).], in which the authors claimed that the method can resist the special attack. However, I think their attack analysis and algorithm are ill-considered and worth discussing.

We analyze and present an attack scheme of the asymmetric optical cryptosystem proposed recently based on coherent superposition and equal modulus decomposition [Opt. Lett.40, 475 (2015)OPLEDP0146-959210.1364/OL.40.000475]. We prove that the attacker can recover the original image with the ciphertext and public keys through the amplitude-phase retrieval algorithm by using two constraints. One constraint of the amplitude-phase retrieval algorithm is the public key and the other is obtained through the analysis of the cryptosystem. The simulation results demonstrate the feasibility of the attack method.

Wei Liu, Zhengjun Liu, Shutian Liu

We appreciate the comment by He et al. [Opt. Lett.38, 4044 (2013)] in the sense that it allows us to clarify our methodology of constructing an optical asymmetric cryptosystem, especially the relationship of the public encryption keys and private decryption keys. We also take this opportunity to provide a more detailed discussion to promote the research about the optical encryption schemes with asymmetric keys into a more correct direction.
