摘　　要：提出一种基于视觉密码的远距离光学信息认证系统。该系统可将远处的视觉密钥通过望远镜系统与系统内的视觉密钥配对实现非相干叠加以完成认证操作,减少了共享密钥的人为传递过程,也解决了实际应用中密钥携带运输不方便的问题。而且,在整个提取过程中视场受限于系统,仅操作者能在系统内看见认证信息,其他人即便在附近也无法查看,加强了信息显示和复现的安全性。认证的过程仅需要操作者将两块共享密钥仔细对准即可,无需其他的光学和密码学知识,整个过程简单高效。此外,光学实验也证明了该系统可应用于实际且具有很高的安全性。A remote optical information authentication system based on visual cryptography is proposed in this paper. The system can pair distant visual key with visual key in the system by telescope system to achieve incoherent superposition for authentication operation, which not only reduces the manual transfer process of the shared keys, but also solves the problem of inconvenient transport of the keys in practical applications. Moreover, the field of view is limited by the system during the entire extraction process, only the operator can see the authentication information in the system, and others cannot view it even if they are nearby, which strengthens the security of the information display and reproduction. The authentication process only requires the operator to align the two shared keys carefully, without mastering other optical and cryptographic knowledge, and the whole process is simple and efficient. In addition, optical experiments also prove that the system can be used in practice and has high security.
