Abstract A general methodology of key-generation of noise-like by use of chaotic process of tent-map function is described in this paper, a mathematics model of noise-like chaotic coding memory is constructed, meanwhile the basic mechanism of circulant convolution and circulant correlation in image information storage and retrieval is demonstrated. Simulation experiments show that image can be correctly recalled from single-pattern and double-pattern of noise-like chaotic coding by use of circulant convolution and circulant correlation operation, and there is a displacement between the last recalled image and the prototype image.
