被认为是使用一个线性代码的“分裂”成相等大小的份额的秘密。确定哪些份额集可以用来获得秘密导致了线性码中最小码字的新概念。结果表明,对偶码中的最小码字完全规定了秘密共享方案的访问结构,反之亦然。
The use of a linear code to "split" secrets into equal-size shares is considered. The determination of which sets of shares can be used to obtain the secret leads to the apparently new notion of minimal codewords in a linear code. It is shown that the minimal codewords in the dual code completely specify the access structure of the secret-sharing scheme, and conversely.
