| 摘 要： | 设计了一个五阶自治的超混沌电路。该电路虽然只含有一个负阻、一个分段线性项，电路结构简单，却可以产生具有三个正性Ｌｙａｐｕｎｏｖ指数的混沌信号。将该电路用于保密通讯中，可提高密文的抗破译强度。

| Abstract: | A fifth-order autonomous circuit with hyperchaos is designed. It contains only a negative resistor and a piecewise linear element.It is simple, but it can generate a hyperchaotic signal with three positive Lyapunov exponents. If the circuit is applied to secure communication systems, the security will be greatly improved. |

| Keywords: | hyperchaos piecewise linearity autonomous circuit positive Lyapunov exponents |
