【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%.更多还原

【Abstract】 A new fault attack was proposed on the basis of combining 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%.更多还原
