| 摘要: |
| 可视密码是一项可以实现可视秘密共享的重要密码技术。它是将生成的分享图像分配给多个参与者，将一定数量的分享重叠就可恢复出原秘密，而不需要任何密码学计算。提出了一种可验证的可视密码方案，该方案引入了行为值得信赖的可信第三方，并引入了基于消息认证模型的公钥密码体系结构，使得每个参与者都可以验证其分享的权威性。该方案解决了分发中心或者分发者的不诚实问题，提高了可视密码方案实施的安全性。 |

| Abstract: |
| Visual cryptography is a cryptographic technique to achieve visual secret sharing. Shares are distributed to several participants and overlapping a number of shares can recover the original secret without any cryptographic computation. A verifiable visual cryptography scheme is proposed to verify whether the share is authorized by introducing the Third Trusted Party (TTP) whose action is guaranteed and the public key cryptographic infrastructure based on message identification model. The scheme solves the problem of dishonest distribution center to improve the security of visual cryptography schemes. |
