低成本紧凑型量子密码

Low Cost and Compact Quantum Cryptography

J. L. Duligall, M. S. Godfrey, K. A. Harrison, W. J. Munro, J. G. Rarity

摘要:

我们提出了一种新的自由空间量子密码系统的设计,完整的专用软件,可以在日光条件下运行。发射器和接收器模块使用廉价的现成组件构建。这两个模块都很紧凑,可以在几米的短距离内按需生成更新的共享秘密。软件的分析,以及错误率的结果,因此在不同的背景光水平共享的秘密收益率。由于该系统的设计,最终在短距离的消费者应用程序中工作,我们还提出了一个使用场景,消费者可以定期“顶”的秘密存储在各种一次性密码本和身份验证协议中使用。

英文摘要:

We present the design of a novel free-space quantum cryptography system, complete with purpose-built software, that can operate in daylight conditions. The transmitter and receiver modules are built using inexpensive off-the-shelf components. Both modules are compact allowing the generation of renewed shared secrets on demand over a short range of a few metres. An analysis of the software is shown as well as results of error rates and therefore shared secret yields at varying background light levels. As the system is designed to eventually work in short-range consumer applications, we also present a use scenario where the consumer can regularly 'top up' a store of secrets for use in a variety of one-time-pad and authentication protocols.
