基于双混沌的视频光学加密技术研究

摘要

对双随机相位编码系统进行了改进,提出了一种基于双混沌系统的光学单通道视频加密的方法.该方法在降低系统复杂度的同时,提高了加密效率,增强了系统的抗攻击能力和安全性能.对加密技术的仿真结果表明,该加密技术能够将视频加密速率提升到光速等级,突破了目前视频加密算法给传输过程带来的瓶颈制约,能够获得预期的视频加密效果,并具有较强的抗攻击能力.%Using double ultra-chaotic system modified the double random phase encoding system,this paper proposed a single channel video encryption method using double chaotic systems.This method reduced complexity of the system,at the same time,it improved the efficiency of the encryption,and enhanced the ability against the attack and the safety performance of the system.This paper simulated the proposed encryption techniques.The result shows that,the proposed encryption technology makes the video encryption speed up to the speed of light level,breaks through the transmission bottleneck restriction which comes from the current video encryption algorithm,achieves the desired effect of video encryption,and has strong anti-attack capability.
