| 摘 要： | 混沌系统特有的一些优良属性较适合流密码的设计，比如混沌迭代序列对初始条件和控制参数的敏感性、伪随机性、混和性和确定性等。该文以Logistic映射为例说明了其主要特性和初值敏感性，并重点图示了在字节输出方式下和比特输出方式下，其离散分布和均匀分布的差异和改善。 |
| 关 键 词： | 流密码 伪随机性 混沌 Logistic |

| Abstract: | Some particular attributes of chaos system are more suitable for stream cipher design, such as the sensitivity to initial conditions and control parameters, pseudo randomness, mixing and exactness, etc. Taking Logistic mapping as example, this paper shows out its primary characteristics, illustrates the difference and improvement of the discrete distribution and uniform distribution under conditions of the standard byte output method and the improved bit output method. |
| Keywords: | Stream cipher Pseudo randomness Chaos Logistic |
