门限视觉密码方案的组构造方法

Group construction method of threshold visual cryptography schemes

提出了视觉密码的组构造向量的概念和基于组构造向量构造基础矩阵的方法,获得了组构造向量的通解,进而获得了成组的视觉密码方案的通解。利用组构造向量,任何人都可以根据公式简单有效地构造出视觉密码方案。另外,还对d=m的方案和既约的方案进行了研究。组构造向量的概念及其通解还为视觉密码的进一步研究提供了很有价值的思路。

The concept of group construction vector for visual cryptography was proposed, and the method based on group construction vector was presented for constructing basic matrices. The complete solutions of group construction vector and that of grouped visual cryptography schemes were obtained. Using the group construction vectors, everyone can construct visual cryptography schemes simply and effectively according to the formulas. The schemes with d=m and irreducible schemes also were researched. The concept and the complete solutions of group construction vector can also present very valuable ideas for the further research on visual cryptography.
