摘要: 将(k,n)彩色视觉密码系统概念推广到一般接入结构上,并给出(k,k)彩色视觉密码系统一个新的构造方法,借助区组设计构造了一类(k,n)彩色视觉密码系统,从而使所看到任意颜色数和参数的(k,n)彩色视觉密码系统是存在的.

关键词: 区组设计, 秘密共享, 彩色视觉密码系统

Abstract: An extended coloured k out of n secret sharing scheme for general access structures is proposed, and a new method to construct coloured k out of k secret sharing schemes is given, with a class of coloured k out of n secret sharing schemes constructed by block design. It is shown that there exists a coloured k out of n secret sharing scheme for any parameter k and n such than kn.

Key words: block design, secret share, colour visual secret sharing schemes
