摘　　要：混沌动力学系统在一定的参数范围内出现混沌运动,且其产生的混沌序列具有良好的伪随机性、遍历性和初值敏感性。通过采用Logistic混沌映射构造单向散列函数来生成散列值,实验结果表明:该方法实现简单,对初值有高度的敏感性,具有良好的单向散列性能。The chaotic dynamics system shows chaotic character if its parameters in the confined range, and the chaotic sequence produced from it have good performance in pseudo-randomicity, ergodicity and sensitivity to initial values. One way hash function based on logistic mapping was used to produce hash values. The experimental result shows that this method is implemented easily, and it has high sensitivity to initial values. This method has a good hash performance.
