用后量子加密保护量子网络的古典通信通道
Quantum-Resistant Networks Using Post-Quantum Cryptography
- 以后量子密码技术加固经典通信链路
- 支持量子纠缠通信与经典链路双安全
- 适合构建抗量子攻击的未来量子网络
量子网络依赖量子与经典信道协同运行。现有架构通过量子信道分发纠缠和密钥，但常假设经典通信足够安全。实际上，传统加密在量子攻击下仍脆弱，因大规模量子计算机可破解主流公钥方案，并削弱对称加密的有效安全性。本文提出一种抗量子网络架构，利用后量子密码技术保护经典通信，同时支持量子信道上的纠缠通信。该框架还集成对量子与经典层的持续监控，并实现异构基础设施间的协同调度，保障端到端安全。这些机制共同为可扩展、鲁棒且安全的量子网络提供路径，使其在经典与量子时代均具备抗威胁能力。
原文摘要 · Abstract (English)
Quantum networks rely on both quantum and classical channels for coordinated operation. Current architectures employ entanglement distribution and key exchange over quantum channels but often assume that classical communication is sufficiently secure. In practice, classical channels protected by traditional cryptography remain vulnerable to quantum adversaries, since large-scale quantum computers could break widely used public-key schemes and reduce the effective security of symmetric cryptography. This perspective presents a quantum-resistant network architecture that secures classical communication with post-quantum cryptographic techniques while supporting entanglement-based communication over quantum channels. Beyond cryptographic protection, the framework incorporates continuous monitoring of both quantum and classical layers, together with orchestration across heterogeneous infrastructures, to ensure end-to-end security. Collectively, these mechanisms provide a pathway toward scalable, robust, and secure quantum networks that remain dependable against both classical and quantum-era threats.
