摘要:

利用广义分圆类构造了一类具有周期$2p$的二元序列,并利用高斯周期和群环理论确定了它们的线性复杂度、${\mathbb{F}_{q}}$上的极小多项式和2-adic复杂度.结果表明,当序列的线性复杂度为$p\equiv \pm 1(\bmod~8)$时,序列的线性复杂度达到最大值;当序列的线性复杂度为扩域上的$p\equiv \pm 3(\bmod~8)$时,序列的线性复杂度为{ $p$ +1}。此外,这些序列的2-adic复杂度是最大的。根据Berlekamp-Massey(B-M)算法和有理近似算法(RAA),这些序列在线性复杂度和2-adic复杂度方面具有很好的密码学性质。

英文摘要:

A class of binary sequences with period $2p$ is constructed using generalized cyclotomic classes, and their linear complexity, minimal polynomial over ${\mathbb{F}_{q}}$ as well as 2-adic complexity are determined using Gauss period and group ring theory. The results show that the linear complexity of these sequences attains the maximum when $p\equiv \pm 1(\bmod~8)$ and is equal to {$p$+1} when $p\equiv \pm 3(\bmod~8)$ over extension field. Moreover, the 2-adic complexity of these sequences is maximum. According to Berlekamp-Massey(B-M) algorithm and the rational approximation algorithm(RAA), these sequences have quite good cryptographyic properties in the aspect of linear complexity and 2-adic complexity.
