A Scheme of Video Encryption Based on Compound Chaotic Sequences
Jingjing Zhang · Journal of Jiangxi University of Science and Technology · 2008
This paper presents a scheme of video encryption based on compound chaotic system.This approach first transfers the pseudo-random sequences which are produced by the compound chaotic system to secret key sequence and permutation matrix,then encrypts the DCT coefficients of video with secret key sequence,and permutates the block of each video frame with permutation matrix.The analysis results indicate that this approach owns the advantages of flexibility,high security,high speed encryption and fixed size preservation and format compliancy.
