A Stream Cipher Based on Discretized Spatiotemporal Chaotic System


The floating-point operation makes the spatiotemporal chaos based cryptosystems difficult to be analyzed. In this paper, according to the design principles of confusion and diffusion, the coupled map lattice (CML) is discretized and a new stream cipher with the discretized CML is proposed. We show the proposed cipher can be clearly analyzed by using proper… (More)
