| Abstract: | In this paper,a technique of generating spatiotemporal chaotic binary sequences based on coupled map lat- tices model is proposed and the performances of binary sequences are analyzed in detail. The results indicate that this kind of spatiotemporal chaotic binary sequence has very ideal randomicity and excellent correlation. Moreover,chaotic sequences can be easily generated and controlled, and possess properties of higher linear complexity and sensitivity with respect to the system parameters,so they are very suitable to application in secure communication and cryptolo- gy. |
