Abstract

This paper proposed a pseudorandom coupled mapping lattice system scheme based on two-dimensional dynamic cellular automata to address the issue of insufficient chaos intensity in spatiotemporal chaotic systems. The two-dimensional dynamic cellular automata were designed based on elementary cellular automata, which achieved state diversity update through varying iteration counts and dynamically selecting iteration rules and directions, thereby enhancing the pseudorandom properties of the cells. During each cell state update, coupling index values were dynamically generated based on the row and column positions of the corresponding cells, and these index values were used to perturb the chaotic sequences, improving their randomness and reducing correlations between cells. Analysis of the system's dynamic characteristics revealed strong chaos and randomness, effectively extending the system's period and enhancing ergodicity. Finally, an image encryption algorithm was designed using SHA-256 operations to generate initialization parameters for the chaotic system, combined with the system's output sequence and DNA encoding. Performance analysis of the algorithm, including information entropy, showed that it possesses good statistical properties and security, promising high application potential in the field of image encryption.
