Handheld quantum wireless for financial transactions

量子密钥分发(QKD)是一种密码方案，提供了前所未有的数据安全级别。它可以用来保护通过ATM机和无线支付进行的金融交易。我们的项目旨在开发一个自由空间、手持(信用卡大小)、可操控的QKD系统原型，以确保现实世界的银行/支付交易。我们的行业领导者Cognizant Technology Solutions(财富500强公司)在数字金融交易处理和信息安全方面拥有20多年的经验。Cogizant将涉及贸易、卡、支付和其他工具的处理逻辑的广泛知识带到桌面上。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。为了显示规模，他们在全球拥有2,000名IT专业人员从事安全实践，100,000名从事金融服务。其中，5000家总部设在英国，Cognizant有在当地建立能力的机制。布里斯托尔大学是量子通信的先驱，尤其是在1990年率先演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，包括发明了目前速度最快的室内光学无线系统，以及创纪录的QKD现场试验。该联盟了解真实世界的银行交易需求，并拥有开发新的光学技术的知识，以量身定做实用的手持QKD系统，具有合适的硬件到用户接口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QKD的领先地位，我们也处于量子技术发展的前沿。使用真实的银行/支付交易数据，这个项目将展示世界上第一次在无线金融应用中使用QKD。

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.
