A bstr act : The 1D chaotic image encryption method is reported with appropriate performances by using the appropriate complexity, pseudo- randomness and extreme parameter sensitivity of chaotic sequences but with smaller key space as its serious drawback compared with others.So, a new image encryption method based on 3D chaotic system is proposed in this paper, which can not only increase secret key space, but also tone up ability to deciphering.And in this paper, the pixel value of cipher- image used to get secret key and the feedback used in encryption process improve greatly the performances of the diffusion function.The method is proved to work well by the result, because of its larger secret key space and high speed of encryption and so on. Key words: 3D chaotic system chaotic sequence image encryption
