An Efficient Chaotic Cryptosystem for Real-time MPEG Video Encryption Algorithm using Arnold’s Cat Map and Henon Map

Abstract

Rapid growth in network communication, there is need development inorder to provide the security
for sensitive data from leakages. Many algorithms were designed for past years but they are not well
proficient while concerning multimedia elements such as image and video due to high complexity of
encoded /decoded, high correlation among all the pixels. Chaos based encryption algorithm has
suggested to deal with these problems because it has desirable features of generate pseudo random
number, sensitivity to initial conditions. A multimedia element video is bounded of audio and image
so video encryption is to consider crucial part and critical task. The intent of proposed method is to
secure the secret video clip by encryption using Arnold’s Cat Map and Henon chaotic map. In this
method, video is extracted into frames and equal size of chaotic sequences is generated. Original
pixel values are shuffled using cat map and its result is XORed with the chaotic sequences of Henon
Map. Further, security of the implemented algorithm is evaluated by experiments on different input
video clips and result produced in less complexity with high security. Finally conclude that this
system is efficacy and provides two layers of security for transmission of multimedia element video.
