Abstract: Abstract In this paper, we proposed an iterative attacking algorithm to the pure phase asymmetric optical cryptosystem based on unequal modulus decomposition. Furthermore, we have proposed a secure asymmetric cryptosystem based on cascaded unequal modulus… read more here.

Abstract: Abstract In this paper, we propose an asymmetric color-image cryptosystem based on spiral phase transform (SPT) and equal modulus decomposition (EMD). The original image is divided into three-channel components of R, G and B firstly.… read more here.
