A novel bit-level color image encryption using improved 1D chaotic map

This paper introduces new simple and effective improved one-dimension(1D) Logistic map and Sine map made by the output sequences of two same existing 1D chaotic maps. The comparison analysis of the proposed improved 1D chaotic map and previous 1D chaotic map confirmed the accuracy of the improved chaotic map. To investigate the applications of the improved chaotic system in image encryption, a novel bit-level image encryption system is proposed. Experiments and analysis prove that the improved chaotic map and the algorithm has an excellent performance in image encryption and various attacks.
