当信息在第二类窃密信道中传输时,线性码的广义汉明重量谱完全描述的它在该信道中的密码学特征.计算一个线性码的广义汉明重量谱是一个基本问题,首先提出了线性码的“最简基”的概念.在此基础上给出了一般线性码子码的几种计数公式,并给出了它们之间等价性的证明.
When the information is transmitted in the second type of theft channel, the generalized Hamming weight spectrum of the linear code completely describes its cryptographic characteristics in the channel.Calculating the generalized Hamming weight spectrum of a linear code is a basic problem, firstly, The concept of “simplest base” of linear codes is given, and several counting formulas of general linear code codes are given, and the proof of equivalence between them is given.
