Abstract :
This paper proposed a novel chaotic image scrambling scheme based on dynamic twice interval-division. The new algorithm works quickly, and has a large cryptographic key space. The paper also analyzed the scrambling performance of the new algorithm statistically. The results indicate that the new algorithm can provide high level security owing to making the relations between the consecutive values of chaotic sequence more complex.
