Image encryption using high-dimension chaotic system

In recent years, the chaos based cryptographic algorithms havesuggested some new and efficient ways to develop secure imageencryption techniques. This paper proposes a new approach for imageencryption based on a high-dimensional chaotic map. The new schemeemploys the Cat map to shuffle the positions, then to confuse therelationship between the cipher-image and the plain-image using thehigh-dimensional Lorenz chaotic map preprocessed. The results ofexperimental, statistical analysis and key space analysis show thatthe proposed image encryption scheme provides an efficient and secureway for real-time image encryption and transmission.
