In order to alleviate the effects of finite precision on chaotic system,chaotic sequence disturbing arithmetic is brought out.After analyzing the characteristics of quantization error on Logistic chaotic sequence,chaotic sequence disturbing arithmetic on Logistic chaotic sequence is researched in which the output of Logistic chaotic sequence is changed by chaotic sequence.The simulation result shows that the perturbing scheme is effective in sequence randomness and periodic aspect.Then image encryption based on chaotic sequence disturbing is proposed and the analysis shows the image encryption algorithm has a good effect.
