Abstract

The advent of chaos theory has brought significant advancement in the field of cryptography. In recent years, chaos-based cryptosystems have been an active area of research. This is due to the fact that properties of chaotic systems and cryptographic primitives share unique characteristics that allow for the chaotic systems to be applied to cryptography. A chaos-based cryptosystem that utilizes a chaotic system that contained chaotic structures and complex dynamical behavior makes it next to impossible for the adversary to gain access to the message either on transit or on storage without any knowledge of the key. Studies have shown that 3-D continuous-time chaotic systems are found to contained in abundance chaotic structures and complex dynamical behavior which could improve the quality and security of a cryptosystem and hence the need to explore the Rucklidge chaotic system. This paper proposed image encryption algorithm for RGB images using the Rucklidge chaotic system. The proposed algorithm adopted the classic framework of the permutation substitution network in cryptography by using the rich chaotic properties of the Rucklidge system which produced required confusion and diffusion properties for a secure cipher. A standard test image namely mandrill_colour_200.tif was used in testing the proposed scheme. Security analysis such as the Histogram Uniformity Analysis (HUA), Correlation Coefficient Analysis (CCA), Number of Pixels Change Rate (NPCR), and the Unified Averaged Changing Intensity (UACI) were carried out on the proposed scheme. Results obtained show that the proposed scheme is effective and strong against the statistical, differential and brute-force attacks.
