چکیده انگلیسی
This paper proposes an attack model to break the security of an image cipher entitled with “Reusing the permutation matrix dynamically for efficient image cryptographic algorithm” developed by Chen et al. The attack model uses only two chosen plain-images to recover any image of size 256â¯Ãâ¯256 while it requires four chosen plain-images to reveal images of larger sizes. The paper also suggests an image cryptosystem to overcome the security inadequacies of the scheme under study. The proposed scheme utilizes multi-chaotic systems and a self-generation mechanism to scramble and diffuse a plain-image based on both the secret key and specific features of the plain-image. This promotes the security level of the proposed cipher as illustrated by the conducted security analysis and experimental results.
