Singapore - Draft Reference Specification for Secure Deployment of Quantum Key Distribution Networks

​The IMDA Reference Specification for Quantum Key Distribution Networks (RS QKDN) was published in June 2023 to guide the deployment and interoperability of QKDN infrastructure in Singapore. Building on this foundational specification, the Reference Specification for the Secure Deployment of QKDN focuses specifically on the security architecture, risks, and countermeasures needed to ensure the resilience and trustworthiness of QKDN implementations.

This security-focused specification provides practical guidance to safeguard the end-to-end operations of QKD networks (QKDNs). By aligning with this specification, implementers and operators can establish a robust security baseline that strengthens trust in QKD-enabled systems and ensures secure integration with conventional networks.​
