作为Y-00量子流密码的安全参数，讨论了窃听者对合法用户的秘密密钥的猜测概率。假设EVE采用Y-00密码信号的每个强度水平的直接检测和高斯强度分布相同，则在得出了仅密文攻击的情况下正确猜测秘密键的概率的分析解决方案。该解决方案用于实验测量我们的Y-00量子流密码收发器的概率。实验证实了Y-00密码收发器的概率非常低。
As a security parameter of Y-00 quantum stream cipher, a guessing probability by an eavesdropper for a secret key of legitimate users is discussed. Assuming that Eve employs the direct detection and Gaussian intensity distribution of each intensity level of Y-00 cipher signals are same, an analytic solution of probability of correct guessing of the secret key in a case of the ciphertext-only attack is derived. The solution is applied to experimentally measure the probabilities of our Y-00 quantum stream cipher transceiver. A very low probability of the Y-00 cipher transceiver is experimentally confirmed.
