Abstract : With the advent of internet and mass media in recent years, online storage of multimedia data in the form of
images and videos has become essential. Thus the security of such data also plays a vital role. In this paper, a novel image
encryption scheme based on cellular automata (CA) and chaotic logistic mapping has been presented. The logistic chaotic
mapping is used for shuffling the pixels which results in permutation. This permuted image is converted into a binary stream
image where each rows of the image are converted into binary streams. Then a hybrid cellular automata (HCA) is used to
provide diffusion by local interaction of the adjacent bits by applying various CA rules in the permuted image and confusion
is brought by the cellular automata rules and keys from pseudo random number generator. In this scheme both reversible and
irreversible cellular automata are used where irreversible cellular automata is used as a Pseudo Random Number Generator
(PRNG) and reversible CA is used for diffusion. The properties of the encrypted image such as entropy, correlation
coefficients, histogram, key space and key sensitivity prove that the encryption scheme is highly robust against attacks and
also reliable in transmission loss scenarios.
Keywords—cellular automata, chaotic logistic mapping, diffusion, encryption.
