一种基于排列组合的视觉密码方案

A Visual Crypotography Scheme Based on Permutation and Combination

视觉密码技术是近年来兴起的一种信息安全加密技术,为了得到一种简单有效的加密方法,可以从Naor和Shamir的视觉密码的基本思想出发,进行分析拓广,制定出一种基于排列组合原理的方案,基础矩阵构造根据每列中代表黑色像素的"1"的个数的变化选取。算法简单可行,易于操作,有实际意义。

Visual Cryptography Technology is a kind of arisen information security encryption technology in recent years. Since 1994, Naor and Shamir put forward that at European Association for Cryptologic, many studies tend to increase the encryption step, and as well make the ncryption scheme complicated. In order to put forward a kind of simple and effective encryption method, this paper introduces the Naor and Shamir visual password basic thought, and analyzed outreach, this paper presents a scheme based on permutation and combination principle, fundamental matrix struct＇ selection according to the different of the number of black pixels ＂1＂ . This algorithm is simple and feasible, easy to operate, and also has practical significance.
