| 摘 要： | 针对可视秘密分享方案存在的安全隐患,提出了一种改进的可防欺骗的可视秘密分享方案。本方案通过改变验证图像的分享方式,让构造者Dealer参与到验证过程,不仅可验证参与者的欺骗行为,还可以验证构造者Dealer和第三方的欺骗。提高了整个分享过程的安全性,并通过汉明重量与仿真结果证明了其可行性与实用性。

| Abstract: | This paper based on the hidden trouble of visual cryptography scheme and proposed an improved visual secret sharing scheme to prevent cheaters. The scheme made Dealer involve the verification process by changing the sharing of verifying image. Not only can prevent the cheating of participants, but also can verify Dealer and the third party's cheating. Then, it improved the security of the sharing process and we can prove its feasibility and practicality through the Hamming Weight and simulation results. |
