Abstract: The notion of k-error exhaustive entropy is proposed, which is based on exhaustive entropy used to measure the strength of random-like property of chaotic sequences, and its two basic properties are proved. Then the method is used to analyze the stability of random-like property of three common continuous chaotic systems, such as Lorenz system, R?ssler system, and Chua’s system. Simulation results show that the approach can reflect the random essence of continuous chaotic system and Chua’s system is better than Lorenz system and R?ssler system as the source of randomness.

Key words: continuous chaotic system, random-like property, stability, k-error exhaustive entropy
