Known-public key attack on asymmetric optical image cryptosystem
-
摘要: 为了破解基于相位截断傅里叶变换的非对称光学图像加密系统，提出一种已知公钥的攻击方法，并通过理论分析和实验仿真进行了研究。结果表明，在已知公钥的攻击下，攻击者可通过获取通用解密密钥恢复基于相位截断傅里叶变换的非对称光学图像加密系统的明文，并取得了较好的破解效果。在整个攻击的实施过程中，除了公开的加密密钥，无需额外的资源，同时攻击难度大大降低，因此更具实际意义。Abstract: In order to break the asymmetric optical image cryptosystem based on phase-truncated Fourier transforms, known-public key attack method was proposed. Through theoretical analysis and experimental simulation, an attacker can get the general decryption key, recover the plaintext of asymmetric optical image encryption system based on phase truncation Fourier transform and achieve the good crack effect under the known public key attack. During the whole attack process, the method needs anything except for the public keys and the difficulty of implementation is also reduced. The results show this method has the practical significance.
