Post-Quantum Ready: Integrating OpenSSL, Bouncy Castle, and QKD via KMIP for Future-Proof Key Management

Quantum Key Distribution (QKD) offers a promising leap forward in secure communications, leveraging quantum mechanics to establish unconditionally secure keys. However, real-world deployment of QKD requires interoperability with traditional cryptographic libraries and key management systems. In this session, we outline our experiences in how to use OpenSSL and Bouncy Castle with QKD systems using standardized protocols, and how to securely manage and distribute those keys using the KMIP (Key Management Interoperability Protocol) standard. We show practical integration steps and how organizations can use familiar tools—OpenSSL and Bouncy Castle—to bridge today’s cryptographic infrastructure with the quantum-secure future, both with PQC algorithms and QKD hardware solutions.
