【摘要】 提出改进型双随机相位加密系统以增强安全性。针对传统的双随机相位加密系统易被破解的问题，创新性地将单点图像经单像素成像后，对桶探测器信号进行置乱处理并转换为振幅图像，将其作为加密系统的第一个相位掩模（K1），第二个掩模仍采用随机相位。加密后的密文（认证图像A的密文）存储于误导式加密系统。解密时需同时还原认证图像A和K1（复原为单点图像B），两者结合后方可完成认证。若仅破解出图像A，系统将返回误导密文；所有密文（含正确密文）均通过单像素成像生成，且置乱顺序与K1保持一致。该机制通过双图像认证和误导性反馈提升了加密系统的安全性。更多还原

【Abstract】 This paper proposes an improved double random phase encoding system to enhance security. Aiming at the vulnerability of traditional double random phase encoding systems to cracking,we innovatively apply single-pixel imaging to the single-point image,scramble the bucket detector signals and convert them into amplitude images,which serves as the first phase mask(K1)of the encryption system. The second mask still uses random phases. The encrypted ciphertext(ciphertext of authentication image A)is stored in a misleading encryption system. During decryption,both the authentication image A and K1(restored as single-point image B)need to be simultaneously recovered,and only their combination can complete the authentication. If only image A is cracked,the system will return misleading ciphertext;all ciphertext(including the correct ciphertext)are generated through single-pixel imaging,and the scrambling order remains consistent with K1. This mechanism improves security through dual-image authentication and misleading feedback.更多还原
