| 摘 要： | 结合故障攻击与Guess determine攻击的思想, 提出A5/1在另一种模型下的故障分析. 结果表明: 通过引入故障, 可成功过滤占总猜测数99.9%的错误猜测, 最终可完全恢复A5/1的内部状态, 攻击的复杂度约为240, 成功的概率大于99%. |

| Abstract: | A new fault attack was proposed on the basis ofcombining the idea of fault attack with that of guess determine attack, by which 99.9% of wrong guesses can be discarded successfully, and furthermore the inner state of A5/1 can be recovered in the end. The complexity of this attack is about 240, and the success probability of this attack is more than 99%. |
