Security Analysis of Multimedia Data Encryption Technique Using Piecewise Linear Chaotic Maps

Abstract

In the current age of globalization file sharing has become an important part of every business process. Also in recent years, transfer of image or multimedia content across the world has become increasingly popular. To prov ide security, to large amount of multimedia content, a strong cryptographic technique is required, which can secure the multimedia content at desired transmission rate. Unfortunately, none of the traditional cryptographic algorithms provide enough security at required transmission rate. But chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure multimedia or image encryption techniques. T his paper aims to analyze the security of "Multimedia Data Encryption Algorithm", on different kind of multimedia images and further to propose a new encryption technique for multimedia data.
