Selective encryption for format compliance of MPEG based on coupled map lattice
Shunqin Li, Gongxiao Wang, Yuzhu Wang, Ya Hui Ning · 2010
In order to maintain format compliance of MPEG video, some encryption algorithms using spatiotemporal chaotic system for information-carrying fields of MPEG are presented. For balancing the tradeoff between security and performance, a comprehensive algorithm is proposed then. Experiment results and performance analyses show that the proposed scheme achieves format compliance, high security, high compression rate and efficiency.
