视觉零知识身份认证的研究

Research of identity authentication based on visual zero-knowledge proof

零知识证明协议是一种非常强大的密码系统。大部分的零知识身份识别方案的安全性是基于复杂的数学算法,和交互双方大规模的计算,即证明者和示证者。而视觉密码技术是一种特别的不需要了解密码学和相应的复杂的数学计算的密码学。因此提出了一个新的基于视觉密码的零知识身份证明方法,克服了当前零知识身份证明协议依赖计算设备和复杂计算。

The zero-knowledge proof protocol is a powerful cryptographic system. The security of most of the zero-knowledge proof identification protocols is based on complex mathematical algorithms and requires heavy interactive computations for both parties, involving the prover and the verifier. However, visual cryptography is special since it does not require one to know the cryptography and the corresponding complex mathematical computations. In this paper, a new zero-knowledge proof identification method based on the visual cryptography is proposed, it reduces current zero-knowledge proof identification protocol＇s dependence on computing devices and the complex computation.
