An Innovative Approach in Image Encryption

(2014)

Abstract

n this paper, a symmetric key image encryption algorithm has been proposed to encrypt image. At first, a large integer number is taken as input and a set of odious number has been computed from this number.A remainder set is computed by dividing the elements of odious set with 255, the maximum grey value of the image. The remainder set is act as symmetric key. The input im age is diffused based on a set of predefined rules and compression technique. Finally, bitwise XOR operation has been applied between key and diffuse image. The effectiveness of the algorithm has been tested by number of statistical tests like histogram analysis, correlation, NPCR, UACI and entropy test. It has been observed that the proposed algorithm has given better result in all tests.
