Abstract

In the last decades the tremendous usage of multimedia data like audio, video and images through communication channels create a need on the security over networks. Since multimedia content utilize large amount of storage for storing images, audio and video, classical cryptographic algorithms such as DES, AES are not efficient in encrypting multimedia data. In future these data are represented as media stream, like real time audio and video. Therefore it is urgent need to protect the multimedia data from attackers in between communication channels. In this paper we propose a new algorithm that encrypt and decrypt compressed multimedia stream of image or audio or video. The compression results in less time in encrypting data because more compression results in less data volume. Our work ensures that multimedia data streams can be secured according to the requirements of the current scenario.
