摘要: 利用相關攻擊獲得畸變的A5/1序列,再用統(tǒng)計工具對其進行處理可以得出A5/1統(tǒng)計特征,從而找到正確區(qū)分A5/1算法輸出和偽隨機序列的方法。實驗驗證該方法能有效地將A5/1算法輸出和偽隨機序列區(qū)分開來。Abstract: A correlation attack on A5/1 algorithm can be educed by the linear filling weakness in initiate process of A5/1 algorithm. An aberrant A5/1 sequence can be obtained from it, which have treated by statistic tools to get A5/1 statistic trait, so the distinction of A5/1 output from real random sequence can be found. Test results show that this method can work effectively.
