【摘要】 祖冲之算法是我国学者自主设计的序列密码算法,是运用于4G移动通信的密码算法国际标准。该算法采用Z/(2³¹-1)上的16次本原多项式作为其驱动组件,由此称环Z/（2⁸-1）上的本原多项式为类"祖冲之算法"的驱动组件。文中给出了这类驱动组件高效设计的三个技巧,并构造了一个具体的实例。更多还原

【Abstract】 The ZUC stream cipher was designed independently by Chinese scholars, which is an international encryption standard used in 4 G mobile communication. The driving block of ZUC stream cipher is a primitive polynomial of degree 16 over Z/(2³¹-1). As a result,primitive polynomials over Z/（2⁸-1） are called ZUC-like driving blocks to emphasize its connection with ZUC stream cipher. In this paper, we provide 3 ideas to design ZUC-like driving blocks efficiently and an instance is also given.更多还原
