29 Jan 2020  ·  Wang Qiuyan, Wu Chenhuang, Yang Minghui, Yan Yang ·

Sequences with high linear complexity have wide applications in cryptography. In this paper, a new class of quaternary sequences over $\mathbb{F}_4$ with period $2p^mq^n$ is constructed using generalized cyclotomic classes. Results show that the linear complexity of these sequences attains the maximum.
