Though many attacks have been published, no recovery attack better than Naya-Plasencia＇ s results with 256 bit keystream limitation. Similar approach is shown and found a specific parity check and decimation. Then an improved distinguisher is constructed for Achterbahn-128 to recover the key with only O （255） keystream bit and O （2102） time complexity. Furthermore, this result is much more effective than the former.展开更多
