Analysis of Chaos-based Feedback Cryptographic Scheme of Human Video Objects
Zhen Liu · Jisuanji gongcheng · 2007
This paper analyzes the security of the chaos-based feedback cryptographic scheme of human video objects and gives a divide-and-conquer attack algorithm against it by using the incompleteness of which the key information diffuses in keystreams.The exhaustive complexity is 2~(21)and the success rate of the attack algorithm is 1.The decrease of key entropy is 235bits.So this encryption algorithm is insecure.
