We demonstrate a new approach to known-plaintext attack on an optical encryption scheme based on double random phase keys. With this attack an opponent can access both random phase keys with the help of the phase retrieval technique. This demonstration shows that an optical encryption scheme based on double random encoding is vulnerable to known-plaintext attack.
我们展示了一种针对基于双随机相位密钥的光学加密方案的已知明文攻击新方法。通过这种攻击，对手可以借助相位恢复技术获取两个随机相位密钥。此演示表明基于双随机编码的光学加密方案易受已知明文攻击。
