Quantum Secure Key Management & Delivery Protocol in the QKD framework
Manjiri Harmalkar, Kurunandan Jain, K. Suresh Kumar, Prabhakar Krishnan · 2024
The current Quantum Key Distribution (QKD) key delivery API relies on HTTPS for secure communication. It is vulnerable to quantum computer threats due to its use of public key cryptography. To mitigate insider attacks, leveraging quantum computing threats within the security boundary and encrypting communication between the application and the KMS is essential. This paper focuses on simulating a 2-node QKD topology using the DARPAN Application. Additionally, we conduct tests on QKD KMS APIs with the Postman tool to ensure consistent retrieval of shared keys at both communication endpoints. Through our simulations and tests, we aim to validate the effectiveness and reliability of the proposed approach in securely managing cryptographic keys within the QKD-network.
