Matthews [1] 提出了一种基于混沌理论的函数,用于生成随机数序列,就像一次性密码本一样使用。当在数字计算机系统上实现时,这些函数必须产生重复的值循环。事实证明,周期长度是不可预测的,而且通常很短。该函数不适合以 Matthews 提出的方式进行加密使用。
Matthews [1] has proposed a function based on chaos theory for generating sequences of random numbers to be used like a one-time pad. When implemented on digital computer systems, these functions must produce repeating cycles of values. The cycle length turns out to be unpredictable and often short. The function is not suitable for cryptographic use in the manner proposed by Matthews.
