An image encryption algorithm based on modified logistic chaotic map

In order to improve the problems of small key space and poor security when the one-dimension logistic chaotic map is applied in image encryption, we propose a modified Logistic chaotic map. Based on the modified Logistic chaotic map, a new image encryption algorithm is introduced. The experimental simulation proves the feasibility of the proposed algorithm. The safety performance analysis shows that the algorithm has infinite key space and high security, and can resist the attack of the exhaustive method and statistical analysis.
