极小三元线性码的两种构造

Two Constructions for Minimal Ternary Linear Codes

Haibo Liu Qunying Liao, Canze Zhu

摘要:

近年来,极小线性码因其在秘密共享方案、两方计算等方面的应用而得到了广泛的研究,构造不满足Ashikhmin-Barg条件的极小线性码并确定其权分布是编码理论和密码学中的一个热点问题。本文利用指数和、Krawtchouk多项式以及$\mathbb{F}_3^m$中定义在特殊向量集上的函数,提出了两类新的不满足Ashikhmin-Barg条件的极小三元线性码,并确定了它们的完全重量计数元.特别地,一类这类码的最小距离优于在\cite{Heng-Ding-Zhou}中构造的码。

英文摘要:

Recently, minimal linear codes have been extensively studied due to their applications in secret sharing schemes, two-party computations, and so on. Constructing minimal linear codes violating the Ashikhmin-Barg condition and then determining their weight distributions have been interesting in coding theory and cryptography. In this paper, basing on exponential sums, Krawtchouk polynomials, and a function defined on special sets of vectors in $\mathbb{F}_3^m$, we present two new classes of minimal ternary linear codes violating the Ashikhmin-Barg condition, and then determine their complete weight enumerators. Especially, the minimal distance of a class of these codes is better than that of codes constructed in \cite{Heng-Ding-Zhou}.
