Image encryption algorithm based on two-one-dimension logistic chaotic inter-scrambling systems and m-sequence

Abstract

This paper investigates a new image encryption algorithm based on two-one-dimensional logistic chaotic inter-scrambling systems. The random disturbance is added to obtain a binary chaotic sequence. Meanwhile, m-sequence is further used to disturb the improved logistic chaotic sequence. Algorithm analysis and simulation results show that the improved algorithm has high encryption efficiency and security. It is shown that it is a good solution to the cycle degradation of one-dimension logistic sequence.
