For two odd integers m and s with 1≤s < m and gcd(m, s) = 1, let h satisfy h(2~s-1) ≡1(mod 2~m+ 1) and d =(h + 1)(2~m-1) + 1. The cross correlation function between a binary m-sequence of period 22~m-1 and its d-dec...

几类特殊形式的置换多项式

有限域上的置换多项式在密码学,编码理论和序列设计等领域有着广泛应用,但目前已知的置换多项式的构造还很有限.文章分别给出有限域F_(2~n)上两类形如(x^(2^i)+ηx+δ)~s+x和两类形x^r+δx^s+δ~tx的置换多项式.

为了抵抗已知的攻击，用于分组密码S-盒中的多输出布尔函数应具有较好的差分性质，较高的非线性度和较高的代数次数等密码学性质．在某些分组密码中，还要求这些多输出布尔函数是有限域F2n上的置换，这里n为偶数．文章将F2n分为两个子...

讨论了一类二次函数的Walsh谱,借助线性化多项式的性质和等量代换技巧,将Walsh谱值的计算问题归结为一类线性化多项式的核子空间维数的求解问题,发现该二次函数的Walsh谱与Gold函数的Walsh谱相同。
