Reusing devices with memory in device independent quantum key distribution
Matthew McKague, Lana Sheridan · arXiv (Cornell University) · 2012
Recently, it has been suggested [3] that device independent approaches to quantum key distribution may be of limited utility, since standard protocols could leak key to the adversary when devices are used repeatedly. We propose a means by which devices with memories could be reused from one run of a 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.
