Web1 sep. 2024 · The minimal codewords of a linear code are those whose supports, i.e., the sets of nonzero coordinates, do not properly contain the supports of other nonzero codewords. They are equivalent to circuits in matroids and cycles in graphs. In coding theory, minimal codewords were first used in decoding algorithms [1], [2], [6], [15]. Web15 nov. 2010 · In this paper, we study a set of minimal codewords for certain classes of binary linear codes, and then determine the access structure of secret sharing schemes based on these codes. The paper is organized into five sections. Section 2 introduces a construction of secret sharing schemes based on linear codes.

Web1 mei 2003 · There are several approaches to the construction of secret sharing schemes. One of them is based on coding theory. In principle, every linear code can be used to construct secret sharing schemes. WebIt is known that using bent functions to define binary codewords gives constant amplitude signals. Based on the concept of quarter bent functions, a new inequality relating the minimum order of terms of a bent function and the maximum Walsh spectral magnitude is proved, and it facilitates the generalization of some known results. pmflow
