| Abstract: | This paper proposed a new analyzing method which is based on evolutionary computation against combination stream cipher.The results of experiments have shown that this method has less complexity than robust attack when analyzing Geefe and threshold RNG,and this evolutionary analysis can increase the efficiency of divide-and-conquer attacks against combination stream cipher definitely,so the evolutionary analysis is effective against stream cipher. |
