Abstract: This paper constructs an integer dynamic cross-coupled Tent mapping model based on optimized cross-coupled map lattice model, and integer dynamic Tent mapping is selected as non-linear function. The frequency distribution characteristics, information entropy, phase space structure, Lyapunov exponent and difference distribution characteristics of sequences generated by the model are systematically studied. Simulation results show that sequences generated by the model have good uniform distribution characteristics and independence, and are easy to implement in hardware, which has great application value in cryptography.
