Hybrid PQC and QKD

量子密钥分发（QKD）为安全通信提供了一种物理方法，在未来的全量子世界中，这种方法将继续保持安全。然而，QKD确实需要一个单独的身份验证机制，这可以通过称为后量子密码学（PQC）的新数学技术来提供。该博士项目与国际合作有关，旨在开发新的PQC和PQC认证的新应用，如应用于QKD。国际合作者是Delaram Kahrobaei教授（美国纽约城市大学）和Ludovic Perret教授（法国巴黎索邦大学）。约克大学的博士生将与项目合作伙伴合作开发新的基于pqc的身份验证方法——调查、应用和优化这些技术，以与各种QKD方法一起使用。因此，该项目涉及理论、编码和最终的实际实施，利用了约克大学的QKD设施。这补充并扩展了量子通信中心和更广泛的英国国家量子技术计划正在进行的QKD研究和开发。

Quantum key distribution (QKD) provides a physical approach to secure communications, which will continue to be secure in a future, fully-quantum-enabled world. However, QKD does require a separate authentication mechanism, which could be provided my new mathematical techniques known as post-quantum cryptography (PQC). This PhD project is linked to an international collaboration, to develop both new PQC and new applications of PQC for authentication, as applied to QKD. The international collaborators are Professor Delaram Kahrobaei (CUNY, USA) and Professor Ludovic Perret (Sorbonne University, Paris, France).The PhD student at York will work in collaboration with the project partners on the development of new PQC-based approaches to authentication - investigating, applying and optimising these techniques for use with various approaches to QKD. The project therefore involves theory, coding and finally practical implementation, leveraging QKD facilities at York. This complements and expands the QKD research and development being undertaken in the Quantum Communications Hub and the wider UK National Quantum Technologies Programme.
