丁构造了一个新的分圆类(V0,V1)。在此基础上,描述了周期为pq的广义分圆二元序列的构造,并确定了它们的自相关值、线性复杂度和最小多项式。+e自相关函数CS(w)是3级的,如果p ≤ 3 mod 4,和CS(w)是5级的,如果p ≤ 1 mod 4。+e线性复杂度LC(S)>(pq/2),如果p <$1mod 8,p> q + 1,或p <$3mod 4或p <$− 3 mod 8。结果表明,这些序列在自相关性和线性复杂度方面具有较好的密码学性质。
Ding constructed a new cyclotomic class (V0 , V1). Based on it, a construction of generalized cyclotomic binary sequences with period pq is described, and their autocorrelation value, linear complexity, and minimal polynomial are confirmed. +e autocorrelation function CS(w) is 3-level if p ≡ 3mod4, and CS(w) is 5-level if p ≡ 1mod4. +e linear complexity LC(S)> (pq/2) if p ≡ 1mod 8, p> q + 1, or p ≡ 3mod4 or p ≡ − 3mod8. +e results show that these sequences have quite good cryptographic properties in the aspect of autocorrelation and linear complexity.
