A hybrid RSA and RC6 based secure image cryptography to minimize entropy and enhance correlation

The need of image security is increasing due to image communication is increasing rapidly. There are several different research work are going in this direction but still there is the need of betterment and the possibility of improvement is there. So focusing the security possibility an improved cryptography system based on RSA and RC6 have been proposed in this paper. The specialty of this approach is the number of keys. There are four different keys are needed for decryption process along with the extra shifting of pixels by XOR. This proposed system is efficient because of the number of iterations. The outcomes are accomplished regarding entropy and connection coefficients. The less variety in entropy is accomplished from our methodology which shows the efficiency of our approach.
