随着5G通信网络实现商用，定义未来6G网络的工作已经启动。具有商业可行性的量子通信技术的出现，为这些未来通信网络提供了基于信息论的密钥协商技术，通过量子密钥分发协议实现可证明的抗量子安全通信。然而，商用量子密钥分发系统依赖于密钥协商协议的独立软件实现。因此，尽管这些系统在数学层面可能是安全的，但在软件方面可能存在安全漏洞。为解决这一问题，我们设计了一个标准化筛选模块，该模块可用于概括大多数（即便不是全部）离散变量量子密钥分发协议（包括基于纠缠的协议）中必要筛选过程的描述与执行。我们对量子密钥分发协议后处理阶段底层实现的软件栈进行了总体描述，包括对该协议双向筛选阶段的形式化表述，以及以完全通用方式实现该阶段所需的机制。最后，我们给出了一些常见量子密钥分发协议的示例配置。
With 5G communication networks enjoying commercial adoption, work has begun towards defining future 6G networks. The emergence of commercially viable quantum communication technologies offer these future communication networks information-theoretic key agreement techniques enabling provably quantum resistant secure communications through quantum key distribution protocols. However, commercial quantum key distribution systems rely on independent software implementations of key agreement protocols. Thus, while these systems may be mathematically secure they may incur security vulnerabilities in software. To address this we design a standardized sifting module, which can be used to generalize the description and execution of the necessary sifting in most if not all discrete variable quantum key distribution protocols, including entanglement based protocols. We give a general description of the software stack underlying implementations of the post-processing stage of quantum key distribution protocols, including our formalization of the two-way sifting stage of said protocols and the machinery required to realize it in a completely general manner. Finally, we give some example configurations for some common quantum key distribution protocols.
