论文摘要
本文研究了一种对帐方法，以便在QKD协议中建立无误的秘密密钥。经典的关键分配协议不再是无条件安全的，因为数学问题的计算复杂性迫使遇到困难。在这种情况下，QKD协议提供了最高的安全性，因为它们基于物理量子定律。但是，协议性能可以通过倍数错误降低。显然，应在这种情况下进行和解，以消除合法合作伙伴的错误。提出的方法通过在侧面信息源编码的特殊问题（SLEPIAN-WOLD编码模型）中使用QTC来实现对帐。与最近的相关工作相比，我们的理论假设得到了实验结果的维持，这些结果证实了我们方法在解决和解问题方面的优势。确实，我们方法的集成在安全性方面产生了重要的进步，并且QBER的大幅下降。增益是随着合理的复杂性提高而获得的。此外，我们工作的新颖性是它在Vpitransmissermaker下测试了真实光子系统的对帐方法。
This paper investigates a reconciliation method in order to establish an errorless secret key in a QKD protocol. Classical key distribution protocols are no longer unconditionally secure because computational complexity of mathematical problems forced hardships. In this context, QKD protocols offer a highest level of security because they are based on the quantum laws of physics. But, the protocol performances can be lowered by multiples errors. It appears clearly that reconciliation should be performed in such a situation in order to remove the errors as for the legitimate partners. The proposed method accomplishes reconciliation by using QTC in the special problem of sideinformation source coding (Slepian-Wolf coding model). Our theoretical hypothesis are sustained by experimental results that confirm the advantage of our method in resolving reconciliation problem compared to a recent related work. Indeed, the integration of our method generates an important progess in security and a large decrease of the QBER. The gain is obtained with a reasonable complexity increase. Also, the novelty of our work is that it tested the reconciliation method on a real photonic system under VPItransmissionMaker.
