具有可扩展性的分层可视密码系统的设计与实现

Design and Implementation of Hierarchical Visual cryptography with Expansion less Shares

Pallavi Vijay Chavan, Dr. Mohammad Atique, Dr. Latesh Malik

摘要:

提出了一种新的分层视觉密码思想。分层视觉密码的核心概念是基于视觉密码的。视觉密码学将秘密信息加密成两部分,称为份额。这两个份额通过逻辑XOR操作堆叠在一起,以揭示原始秘密。分层视觉密码学在不同的级别上加密秘密。加密反过来又是不可扩展的。原始秘密大小保留在所有级别的份额中。在本文中,秘密是在两个不同的级别加密。四个份额是从分层视觉密码学中生成的。任何三个份额共同组成关键份额。所有生成的份额都是没有意义的,没有通过目视检查提供任何信息。性能分析还基于各种类别的秘密获得。在显示秘密时完全移除变灰效果移除变灰效果并不改变秘密的含义。

英文摘要:

Novel idea of hierarchical visual cryptography is stated in this paper. The key concept of hierarchical visual cryptography is based upon visual cryptography. Visual cryptography encrypts secret information into two pieces called as shares. These two shares are stacked together by logical XOR operation to reveal the original secret. Hierarchical visual cryptography encrypts the secret in various levels. The encryption in turn is expansionless. The original secret size is retained in the shares at all levels. In this paper secret is encrypted at two different levels. Four shares are generated out of hierarchical visual cryptography. Any three shares are collectively taken to form the key share. All shares generated are meaningless giving no information by visual inspection. Performance analysis is also obtained based upon various categories of secrets. The greying effect is completely removed while revealing the secret Removal of greying effect do not change the meaning of secret.
