摘要
运用高阶差分的思想,对前馈密钥流生成器给出了一种概率攻击算法:即在已知明文攻击时,能较快地求出其反馈多项式的抽头;对于唯密文攻击,只要明文非平衡,则该算法仍然有望成功。
We give a probability algorithm for feedforward key stream sequence generators using higher order differential that it can find quickly feedback polynomial using known plaintext, and it succeed possibly using ciphertext only if plaintext isn＇t balance.
