近年来，双随机相位编码（DRPE）与光子计数（PC）成像技术相结合，实现了图像的安全认证。在该方案中，相同的密钥应该在发送方和接收方之间安全地分发和共享，但这是对称密码系统中最令人烦恼的问题之一。本文结合PC-DRPE和RSA算法，提出了一种高效的非对称图像认证方案，解决了密钥管理和分发问题。所提出的认证方法所检索到的图像包含通过PC-DRPE获得的光子限制加密数据。因此，在保护原始图像的同时，利用统计非线性相关方法可以有效地验证检索到的图像。实验结果证明了所提出的非对称图像认证方法的可行性。
Recently, double random phase encoding (DRPE) has been integrated with the photon counting (PC) imaging technique for the purpose of secure image authentication. In this scheme, the same key should be securely distributed and shared between the sender and receiver, but this is one of the most vexing problems of symmetric cryptosystems. In this study, we propose an efficient asymmetric image authentication scheme by combining the PC-DRPE and RSA algorithms, which solves key management and distribution problems. The retrieved image from the proposed authentication method contains photon-limited encrypted data obtained by means of PC-DRPE. Therefore, the original image can be protected while the retrieved image can be efficiently verified using a statistical nonlinear correlation approach. Experimental results demonstrate the feasibility of our proposed asymmetric image authentication method.
