Arising in recent years, algebraic attack is regarded as one of effective and pervasive attack methods. The method, which has been applied successfully in stream ciphers system based on LFSR, has significant influence on the mechanism of stream ciphers system.
代数攻击是近年来兴起的一种有效而有趣的攻击方法2之一,被成功地应用于一些基于LFSR的流密码系统中,对流密码体制产生了巨大影响,众多密码工作者在代数攻击中求解多变元超定方程组求解、零化子的构造等方面都做了比较有效的研究。
