摘要

针对量子计算对传统公钥基础设施的潜在威胁，通过分析量子密钥分发（quantum key distribution，QKD）与后量子密码（post-quantum cryptography，PQC）技术的互补性及两种技术融合的必要性，提出了一种融合QKD与PQC的密码基础设施功能模型，并具体描述了模型的基本组成网元及其功能模块，定义了各网元与模块间的接口参考点。通过QKD和PQC融合的混合密码系统，实现了属于不同密钥管理系统的语音终端之间的跨域加密通话场景。该模型的提出为电信运营商提升其基础网络与电信业务抗量子攻击能力提供了有力支撑。

Abstract

In view of the threat of quantum computing to traditional public key infrastructure

by analyzing the technical complementarity of quantum key distribution (QKD) and post-quantum cryptography (PQC)

as well as the necessity for integrating these two technologies

A functional model for cryptographic infrastructure that integrates QKD and PQC was proposed

basic network elements and functional modules of the model was described and interface reference points were defined

and an application scenario for cross-domain encrypted calls between voice terminals belonging to different key management systems through a hybrid cryptographic system that integrates QKD and PQC was realized

which provides a strong support for telecom operators to improve the anti-quantum attack capabilities of their basic networks and telecom services.
