针对双随机相位加密方案提出了几种攻击方法。这些攻击在计算机生成的加密图像上得到了验证。该方案被证明能抵抗暴力攻击，但易受选择明文攻击和已知明文攻击。特别是，我们描述了一种仅用两幅已知明文图像就能恢复准确密钥的技术。我们将这种技术与文献中提出的其他攻击方法进行了比较。（c）2007美国光学学会
Several attacks are proposed against the double random phase encryption scheme. These attacks are demonstrated on computer-generated ciphered images. The scheme is shown to be resistant against brute force attacks but susceptible to chosen and known plaintext attacks. In particular, we describe a technique to recover the exact keys with only two known plain images. We compare this technique to other attacks proposed in the literature.
