内部证明加密及其在量子密钥分发中的应用

Insider-proof encryption with applications for quantum key distribution

Matthew McKague, Lana Sheridan

摘要:

已经指出,当前用于设备无关的量子密钥分发的协议在设备被重复使用时可能将密钥泄漏给对手,并且该问题尚未得到解决。我们引入了防内幕渠道的概念。这使我们能够提出一种方法,通过该方法,具有存储器的设备可以从设备独立的量子密钥分发协议的一次运行重新使用到下一次运行,同时将泄漏限制到Eve,假设该协议的一次运行可以使用具有存储器的设备安全地完成。

英文摘要:

It has been pointed out that current protocols for device independent quantum key distribution can leak key to the adversary when devices are used repeatedly and that this issue has not been addressed. We introduce the notion of an insider-proof channel. This allows us to propose a means by which devices with memories could be reused from one run of a device independent quantum key distribution protocol to the next while bounding the leakage to Eve, under the assumption that one run of the protocol could be completed securely using devices with memories.
