| 摘 要： | 论文针对Ｊ．Ｄ．Ｇｏｌｉｃ给出的以钟控序列生成器为组合块的非线性组合生成器的统计模型，文中给出了一种基于转移概率的最大后验概率判炔新方法。这种方法从理论上讲要优于Ｊ．Ｄ．Ｇｏｌｉｃ的基于ＣＬＤ的攻击方法，模拟的结果也证明了这一点。

| Abstract: | Based on the statistical model of the key-stream generator consisting of clock-controlledshift registers combined by a memoryless function,a new maximum posterior probability deci-sion attack algorithm using transition probability is proposed.Its advantage over the attack al-gorithm given by J.D.Golic is theoretically proved and verified by the comparison between ex-perimental results. |
