The wide use of video multimedia applications has made it important to improve the security of video information for streaming it over communication links. In this case cryptography techniques are necessary and the security of video information becomes essential. Existing video encryption scheme address this issue by using chaotic map or standard private key systems. In this paper, we propose an encryption scheme which uses a computationally simple technique like SDES along with a novel frame selection scheme. The use of proposed frame selection mechanism and chaotic map encryption makes the technique easy to implement. Robustness is achieved with the help of RSA encryption on user key parameters. The proposed scheme is evaluated using unique feature such as UACI and NPCR. We tested proposed scheme on videos containing different videos of visual correlation and we find that proposed scheme works reasonably well irrespective of level of visual correlation.
