我们展示了一种基于相移干涉测量 (PSI) 技术的光密码系统已知明文攻击 (KPA) 的新分析方法。通过所提出的分析攻击方法，对手可以获得准确的解密密钥并获得完美的攻击结果。据我们所知，该演示首次表明基于 PSI 技术的光密码系统容易受到 KPA 的攻击。
We demonstrate a new analytic approach to a known-plaintext attack (KPA) on an optical cryptosystem based on the phase-shifting interferometry (PSI) technique. With the proposed analytic attack method, an opponent can access the exact decryption keys and obtain perfect attack results. This demonstration, to the best of our knowledge, shows for the first time that the optical cryptosystem based on the PSI technique is vulnerable to KPA.
