Robust Chaos via Smooth Exponential Map

Fadi Abu-Amara and Ahmed Musa

Abstract—This paper proposes a robust image encryption algorithm via Smooth Exponential Map (SEM) to meet the demand for fast and highly secure image transmission. The proposed algorithm consists of two phases; image-diffusion and image-fusion. In the image diffusion phase, pixel locations of the original image are shuffled in the spatial domain while pixel values are modified in the image fusion phase. Investigating the chaotic map characteristics of proposed SEM indicates a full chaotic behavior. Results of testing the proposed algorithm show that the proposed algorithm has a large key space with complete obscuring of the original image, secured against brute-force attack as it is achieved a large complexity of order( O )  290, and requires 343ms to encrypt200x200 pixels image.

Index Terms—Chaotic map, image encryption, lyapunov exponent, image fusion, image diffusion.
