包含秘密经典数据的标签的量子标记

Quantum Tagging for Tags Containing Secret Classical Data

Adrian Kent

摘要:

各种作者已经考虑了用于{ \it量子标记}的方案,即,在由对手控制的环境中,通过从适当定位的远距离站点发送和接收量子信号来认证经典标记设备的经典位置,对手的量子信息处理和传输功率潜在地是无限的。这项任务提出了一些关于密码安全假设的有趣的新问题,因为安全模型中相对微妙的细节可能会极大地影响可达到的安全性。我们认为在这里的情况下,标签是加密安全的,并显示如何实现标记安全地在这个模型。

英文摘要:

Various authors have considered schemes for {\it quantum tagging}, that is, authenticating the classical location of a classical tagging device by sending and receiving quantum signals from suitably located distant sites, in an environment controlled by an adversary whose quantum information processing and transmitting power is potentially unbounded. This task raises some interesting new questions about cryptographic security assumptions, as relatively subtle details in the security model can dramatically affect the security attainable. We consider here the case in which the tag is cryptographically secure, and show how to implement tagging securely within this model.
