ICSECV: An efficient approach of video encryption

Encryption for the compressed video stream has attracted the attention of many researchers within past few years. Due to exponential growth of digital multimedia contents over the network, their secure transmission over the network is a serious concern. Security and performance are two main peculiarities of any digital multimedia encryption algorithm. This paper presents an indexed chaotic sequence based selective encryption of compressed video (ICSECV) which exploits the characteristics of compressed video. ICSECV selectively encrypts the compressed Intra coded frames and predictively coded frames from each Group of picture (GoP). This method of encryption is quite efficient since it provides the real time encryption of digital multimedia contents. ICSECV uses indexed based chaotic sequence for encrypting the selected frames which do not leaks any information and provide desirable amount of security.
