摘要:

基于量子密钥分配(quantum key distribution,QKD)的通信网络具备实现 “perfect secrecy”(完美保密性)的能力,当前还不能满足大规模应用的需求,在实际应用中需要结合经典密码技术。提出了融合量子密钥分配的电信运营商密码应用体系的功能架构模型,介绍了模型的层次结构、核心的网元和功能模块以及接口关系,给出了应用体系的整体框架,介绍了框架的主要组成部分,描述了应用体系的典型应用场景及其工作流程。

Abstract:

The communication network based on quantum key distribution (QKD) has the ability to realize “perfect secrecy”.At present, it cannot meet the needs of large-scale applications and needs to combine classical cryptography in practical applications.Firstly, the functional architecture model of the telecom-operators cryptography application system integrating quantum key distribution was proposed, and then the hierarchy, the core network elements, the functional modules, and the interface relationships of the model were described.Furthermore, the framework of the application system was given, and the main components of the framework were introduced.Finally, the typical application scenarios and workflow were illustrated.

Key words: quantum key distribution, cryptography, application system
