摘要:

极小线性码在秘密共享方案和安全两方计算中有着有趣的应用。本文利用$\mathbb{F}_q$的某些子集的特征函数构造极小线性码。利用特征函数的性质,我们可以从已知的最小二元线性码中得到更多的最小二元线性码,推广了Ding等人[IEEE Trans. Inf. Theory,vol.64,no.10,pp. 6536-6545,2018]。利用与$\mathbb{F}_q$的某些子空间相对应的特征函数,我们得到了许多极小线性码,推广了[IEEE Trans. Inf. Theory,vol.64,no.10,pp. 6536-6545,2018]和[IEEE Trans. Inf. Theory,第65卷,第11期,第11页]。7067-7078,2019]。最后,利用特征函数从定义集的角度给出了极小线性码的一个刻画,并给出了一类极小线性码。

英文摘要:

Minimal linear codes have interesting applications in secret sharing schemes and secure two-party computation. This paper uses characteristic functions of some subsets of $\mathbb{F}_q$ to construct minimal linear codes. By properties of characteristic functions, we can obtain more minimal binary linear codes from known minimal binary linear codes, which generalizes results of Ding et al. [IEEE Trans. Inf. Theory, vol. 64, no. 10, pp. 6536-6545, 2018]. By characteristic functions corresponding to some subspaces of $\mathbb{F}_q$, we obtain many minimal linear codes, which generalizes results of [IEEE Trans. Inf. Theory, vol. 64, no. 10, pp. 6536-6545, 2018] and [IEEE Trans. Inf. Theory, vol. 65, no. 11, pp. 7067-7078, 2019]. Finally, we use characteristic functions to present a characterization of minimal linear codes from the defining set method and present a class of minimal linear codes.
