Classification of a class of A3MDSA3MDS code and applications in secret-sharing schemes
Abstract
A qq-ary linear [n,k,n−k−(i−1)][n,k,n−k−(i−1)] code ℒ is known as AiMDS code. If d=n−k+1, the code is called a maximum distance separable code. MDS codes are known to be useful in the secret-sharing schemes and coding theory. In this paper, we classify all binary self-orthogonal A3MDS codes. We have introduced a subclass of A3MDS codes, called N3STMDS codes, to form a special type of secret-sharing scheme where for any participant, there exist (k−1) other participants who can collectively reveal the secret by combining their shares and there exists another set of (k+2) participants including the given participant, who cannot reveal the secret.
