Handheld quantum wireless for financial transactions

量子密钥分发（QKD）是一种提供前所未有的数据安全性的加密方案。它可以用来确保通过ATM机和无线支付进行的金融交易的安全。我们的项目旨在开发一个自由空间、手持（信用卡大小）、可操纵的QKD系统原型，以确保真实世界的银行/支付交易。我们的行业领导者，Cognizant Technology Solutions（一家财富500强公司），在数字金融交易处理和信息安全方面拥有超过20年的经验。Cognizant带来了广泛的处理逻辑知识，涉及贸易，卡片，支付和其他工具。他们还了解如何使用当前的加密技术安全地处理客户机密和PII（个人）数据。为了说明规模，他们在全球拥有2000名安全实践IT专业人员和10万名金融服务专业人员。其中，有5000家总部设在英国，Cognizant已经建立了在当地建立能力的机制。布里斯托尔大学是量子通信领域的先驱，特别是在1990年首次展示了自由空间量子传输。(？) 牛津大学在光学无线转向技术方面有着良好的记录，包括发明了目前最快的室内光学无线系统，以及创纪录的QKD现场试验。该联盟了解现实世界的银行交易需求，并拥有开发新型光学技术的知识，以定制实用的手持QKD系统，并配有合适的硬件到用户界面和用于商业部署的软件堆栈。我们寻求机会向世界展示，英国不仅在学术研究方面处于领先地位，而且在量子技术发展方面也处于领先地位。利用真实的银行/支付交易数据，该项目将展示全球首个QKD在无线金融应用中的使用。

Quantum key distribution (QKD) is a cryptographic scheme which provides an unprecedented level of data security. It can be used to secure financial transactions over ATM machines and wireless payments. Our porject seeks to develop a free-space, handheld (credit-card size), steerable QKD system prototype to secure a real-world bank/payment transaction.Our industrial lead, Cognizant Technology Solutions (a Fortune 500 company), has over 20 years of experience in digital finance transaction processing and information security. Cognizant brings to table extensive knowledge of processing logic involved in trade, cards, payments and other instruments. They also understand how to handle client confidential and PII (Personal) data securely using current encryption technologies. To give an indication of scale, they have 2,000 IT professionals in security practice and 100,000 in financial services globally. Out of this, 5,000 are based out of UK and Cognizant has the mechanism in place to build capability locally. University of Bristol is a pioneer in quantum communication, notably being the first to demonstrate free-space quantum transmission in 1990. (?) University of Oxford has a strong track record in optical wireless steering techniques, including inventing the current fastest indoor optical wireless system, as well as record setting QKD field trials.This Consortium understands real-world banking transaction needs and has the knowledge in developing novel optical techniques to tailor make a practical handheld QKD system, completed with suitable hardware-to-user interface and a software stack for commercial deployment. We seek the opportunity to show the world that not only UK is leading QKD in academic research, we are also at the forefront of quantum technology development. Using real bank/payment transaction data, this project will demonstrate the world's first QKD usage in wireless financial application.
