摘要：Given the rapid evolution in imaging andcommunication techniques, images become very importantdata transmitted over public networks type. Therefore, a fastand secure encryption system for high-resolution images is atremendous demand. In this paper, a novel encryptionsystem is proposed to secure images on the basis of ArnoldCatmap. In the First, Arnold cat map system is used toscramble the positions of image pixels. Then, chaotic map isused to generate pseudorandom image for substitution. Thestatistical analysis was performed on the proposedencryption algorithm demonstrating superior confusion anddeployment of its properties, which strongly resist statisticalattacks. Coefficients of correlation between adjacent pixelsshowed that correlation between pixels of the encryptedimage has significantly decreased. It is noted that the numberof pixels of the image encoded drops significantly whichindicates that the proposed system can thwart correlationattacks.
