在量子攻击者存在下利用universal2隐私放大精确评估泄露信息

Precise evaluation of leaked information with universal2 privacy amplification in the presence of quantum attacker

Masahito Hayashi

摘要:

当窃听者具有相关的量子态时,我们处理密钥提取。我们提出了不同于Renner的量子隐私放大定理,它是基于1+s阶量子条件Rényi熵的。利用这些定理,我们得到了一个指数递减率的泄漏信息和渐近含糊率,这还没有得到迄今为止在量子设置。

英文摘要:

We treat secret key extraction when the eavesdropper has correlated quantum states. We propose quantum privacy amplification theorems different from Renner's, which are based on quantum conditional Rényi entropy of order 1+s. Using those theorems, we derive an exponential decreasing rate for leaked information and the asymptotic equivocation rate, which have not been derived hitherto in the quantum setting.
