%X Concerning the characteristics of big data flow, high real-time requirement, a generator on encrypted keys, which was analyzed in detail by maximal lyapunov exponent, was proposed, approximate entropy and L-Z complexity by means of controllable spatiotemporal chaotic sequences combined with the encrypted method of encryption flow based on XOR algorithm. The experimental results show that the encrypted system has high performance at two aspects: both statistics and strengthened sensibility.
