Application of Correlation Attack in Algorithm Identify

摘要: 利用相关攻击获得畸变的A5/1序列，再用统计工具对其进行处理可以得出A5/1统计特征，从而找到正确区分A5/1算法输出和伪随机序列的方法。实验验证该方法能有效地将A5/1算法输出和伪随机序列区分开来。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.
