Abstract: Some image encryption algorithms are difficult to resist the chosen-plaintext attack against special images, in order to solve this problem and improve the security of the algorithm, this paper proposes a novel image encryption scheme… read more here.

Abstract: Cryptanalysis is significant for the design of secure image cryptosystem. Recently, a chaotic image encryption scheme using two rounds of Latin square-based permutation and diffusion was proposed. Although two-round encryption is used, the cryptosystem has… read more here.

Abstract: Abstract In the traditional image encryption systems, the permutation-diffusion operation is often conducted in two essentially separable or independent steps, which appears not only to be inefficient but also vulnerable in being attacked since each… read more here.

Abstract: Abstract. Image encryption plays an essential role in the community of image security. Most existing image encryption approaches adopt a permutation–diffusion scheme to permute pixel positions and change pixel values separately. One limitation of this… read more here.
