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.
