Chaos-based Encryption Algorithm for AVS Video Compression
Donghuan Liu · Jisuanji gongcheng · 2009
An approach of utilizing the chaos to Audio Video coding Standard(AVS) encoded frame is proposed,and it is integrated into the AVS CODEC.This algorithm encrypts DCT nonzero coefficients by using real-value chaotic sequence and then confuses DCT nonzero coefficients.Conducts simulate on three standard video sequence.Simulation results are tested on rm52j software platform,which indicates this algorithm is fast at encrypting data,good at security and affects little to compression.
