Abstract:
Auther proposed a brand new encryption method for video sequence, based on Chaos theory. This method adopted multilayer chaotic transformation,therefore,the key can be changed during theencryption process, and the security performance is greatly improved.Besides, this algorithm inherited the selective encrytion idea, it only processed the key messages in the video sequence, so encryption efficiency is enhanced remarkably to satisfy the requirements of realtime communication. Furthermore, through computer simulations, the security performance and encryption efficiency of this method was demonstrated.

摘要:
提出了一种全新的基于混沌理论的多层次视频流保密方法,此方法由于采用多层次的混沌迭代,因而达到了使密钥实时改变的目的,极大地提高了保密性能。另外,本算法继承了选择加密的思想,只对视频流中包含关键信息的部分进行处理,可以提高加密效率,满足实时交互的要求。分析仿真实验结果,进一步证实了此方法具有很好的保密性能和加密效率。
