RC4 Video Encryption Algorithm Based on Hyper-chaos
Li Tian · Video Engineering · 2015
In view of the safety of video transmission,a novel video encryption algorithm base on hyper-chaos system and RC4 is put forward in this paper.Four chaotic sequences of hyper-chaotic map are used as the key of RC4 algorithm to encrypt DC coefficients,nonzero AC coefficients symbols and motion vector symbols.The experimental results prove that the algorithm has a larger key space,high sensitivity and high key security.
