联邦互联量子密钥分发（QKD）网络正成为常态，且已有多项标准出台，互操作性在技术上已可行。然而，与跨域密钥分发相关的诸多问题仍未解决：漏洞通报与缓解、与空间段的集成、向未来QKD即服务（QKD-as-a-Service）商业模式的扩展、涉及密钥新鲜度、管辖范围、安全等级的定制请求等。我们认为，要从语法互操作性迈向语义互操作性，必须开发一种通用语言，确保密钥与意义一同传输。我们断言这可通过QKD密钥元数据实现，并提出一个6步流程将其开发为标准。
英文摘要
Federated interconnected QKD networks are becoming the norm, and with several standards already in place, interoperability is now technically feasible. Many aspects related to cross-domain key distribution, however, are left unresolved: breach announcement and mitigation, integration with the space segment, extension to a future QKD-as-a-Service commercial model, custom requests referring to key freshness, jurisdictions, security levels, etc. We argue that, to move from syntactic to semantic interoperability, a common language must be developed to ensure transfer of meaning along with the keys. We posit this is possible via QKD key metadata, and we propose a 6-step process to develop it as a standard.
