Image scrambling with wavelet transform and chaos map

Two methods of generating random samples based on chaotic maps were studied to improve the resolution and Electronic Counter-Counter Measure(ECCM) of radar signals.

By introducing binary fraction and its related operations,a novel block cipher based on chaotic maps is proposed in this paper.

It uses two coupled chaotic maps to generate a sequence of chaotic pairs,disorder the original image with the new pixel address codes which are produced by these pairs and gain disordered image,transforms the disordered image by Discrete Cosine Transformation(DCT),and change every DCT coefficient of image with the aid of a chaotic sequence in DCT domain to complete the encryption of image.
