Asymmetric optical cryptosystem based on coherent superposition and equal modulus decomposition: comment
Xiaopeng Deng · Optics Letters · 2015
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.
