A Novel Multiple Segmented Image Encryption

Abstract

Image encryption safeguards information against unauthorised users and has numerous applications in military and communicational systems. Guaranteeing the security and robustness of the image has become a vital factor. This paper proposes a new multiple segmented multiple-image encryption framework by utilising secure force algorithm, Multiple Circular Shifting and Pixel Shrinking (MCSPS) and chaotic permutation techniques. The security of the proposed algorithm is enhanced by operating three different techniques to encrypt each segmented image. Several metrices have been used to evaluate the security of the projected framework against statistical and differential analysis. Experimental results validate that the projected algorithm can survive the statistical and differential attacks.
