摘要

对于整数r≥1，在密码学中引入序列的r阶相关测度(或r阶相关测度)作为抗相关攻击的度量。当r = 2时，它可以看作是给定序列的部分周期自相关幅度子集中的最大值。本文确定了任意周期的Zadoff-Chu序列的二阶相关测度，并证明了二阶相关测度对Zadoff-Chu序列的设计参数不变。

The second-order correlation measure of Zadoff-Chu sequences

For an integer r ≥ 1, the rth-order correlation measure (or the correlation measure of order r) of a sequence was introduced in cryptography as a measure of immunity against correlation attacks. When r = 2, it can be viewed as the maximum value in a subset of magnitudes of partial-period autocorrelation for a given sequence. In this paper, we determine the second-order correlation measure of Zadoff-Chu sequences of any period and show that it is invariant to the design parameter for them.
