Summary:
|
With the growing demand for scalable, low-latency and high frequency key requirements—such as IoT, 5G, and industrial control—it is necessary to enhance QKDN to support secure and efficient key delivery. Due to the low-latency and high frequency key requirements of applications, deploying full-scale QKD modules and key management systems for each service domain is impractical.
To address this, a edge key management architecture is introduced, where edge key management (EKM) are introduced as lightweight key management entities deployed near applications. EKMs collaborate with KM to provide localized key access and caching, while maintaining the key requirements of applications.
Therefore, this Recommendation will carry out standardization work to specify the requirements, functional model, and operation procedure of QKDN for supporting edge key management, enabling flexible, efficient, and secure QKDN support for low-latency and high frequency key requirement.
