Towards efficient and secure quantum-classical communication networks
- 结合QKD与PQC，设计混合加密协议提升安全性
- 解决单一方案在实际部署中的性能与安全短板
- 适合关注量子时代通信安全的研究者与工程师
量子技术的快速发展催生了对量子安全加密协议和通信网络的需求。目前实现抗量子安全的主要途径有两种：量子密钥分发（QKD）和后量子密码学（PQC）。二者虽各有优势，但在实际应用中均存在局限。本文系统分析了这两种协议的优缺点，并探讨其融合的可能性，以在密钥分发中实现更高安全等级或更优性能。我们希望该讨论能推动面向量子-经典通信网络的混合加密协议研究。
原文摘要 · Abstract (English)
The rapid advancement of quantum technologies calls for the design and deployment of quantum-safe cryptographic protocols and communication networks. There are two primary approaches to achieving quantum-resistant security: quantum key distribution (QKD) and post-quantum cryptography (PQC). While each offers unique advantages, both have drawbacks in practical implementation. In this work, we introduce the pros and cons of these protocols and explore how they can be combined to achieve a higher level of security and/or improved performance in key distribution. We hope our discussion inspires further research into the design of hybrid cryptographic protocols for quantum-classical communication networks.
