提出了一种基于双随机相位编码（DRPE）和RSA公钥密码体制的信息隐藏方法。该技术巧妙地利用了DRPE固有的扩散特性，弥补了RSA公钥密码系统的扩散不足，同时利用RSA密码系统实现了DRPE技术无法实现的密文和两个相位掩码的同时传输。该技术结合了DPRE和RSA加密技术的优势互补，为高效的信息传输带来了安全和方便。大量的数值模拟结果，以验证所提出的技术的性能。
A novel information hiding method based on double random-phase encoding (DRPE) and Rivest-Shamir-Adleman (RSA) public-key cryptosystem is proposed. In the proposed technique, the inherent diffusion property of DRPE is cleverly utilized to make up the diffusion insufficiency of RSA public-key cryptography, while the RSA cryptosystem is utilized for simultaneous transmission of the cipher text and the two phase-masks, which is not possible under the DRPE technique. This technique combines the complementary advantages of the DPRE and RSA encryption techniques and brings security and convenience for efficient information transmission. Extensive numerical simulation results are presented to verify the performance of the proposed technique.
