摘要: This paper presents a novel image encryption scheme based on cellular automata (CA) and chaotic logistic mapping. The mapping is used for shuffling the pixels which results in permutation. permuted converted into binary stream where each rows of are streams. Then hybrid (HCA) to provide diffusion by local interaction adjacent bits applying various CA rules confusion brought keys from pseudo random number generator. In this both reversible irreversible as Pseudo Random Number Generator (PRNG) diffusion. properties encrypted such entropy, correlation coefficients, histogram, key space sensitivity prove that highly robust against attacks also reliable transmission loss scenarios.
