This paper proposes a new image encryption algorithm that makes the use of high dimensional fractional order Chua’s chaotic system. Fractional order extension of the Chua’s system gives a much larger key-space than its original integer order version. The proposed image encryption algorithm uses a simple but excellent technique which is quite fast and the encrypted images are found to have very high entropy. The algorithm is shown to be highly robust and almost invulnerable to statistical attacks. Moreover, the algorithm is designed in such a way that it can be extended by incorporating other chaotic systems as well.
