全球首个双重加密量子密码体系发布

Core Viewpoint - China Telecom Quantum Group has launched the world's first distributed cryptographic system that integrates Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC), providing end-to-end quantum-resistant key distribution and lifecycle management, now commercially viable [1][2]. Group 1: Technology and Infrastructure - The "QKD+PQC" distributed cryptographic system employs a three-layer decoupled architecture consisting of the quantum network layer, cryptographic service layer, and application access layer, ensuring physical security for cross-domain key distribution [2]. - The system has been validated in multiple scenarios, marking a significant step towards scalable commercial use of integrated cryptographic technology in China [2]. - China Telecom has established the world's first integrated quantum security infrastructure, supporting the development of quantum security services [2]. Group 2: Implementation and Impact - The Hefei Quantum Metropolitan Area Network, built by China Telecom Quantum Group, is the largest and most comprehensive quantum secure communication network globally, covering 1,147 kilometers of quantum key distribution fiber [3]. - This network serves approximately 500 government agencies and 380 state-owned enterprises, significantly enhancing information security in sectors such as government, finance, and public services [3].
