The Abstract says "Quantum Key Distribution (QKD) is a mechanism for creating shared, secret, random bits. This document describes extensions to the IKEv2 protocol to use random bits created via QKD as keys for IPsec."<p>Section 6 Security Considerations says "Because QKD's principal role is to detect eavesdropping and discard possibly compromised bits, eavesdropping is a very effective denial of service (DoS) attack. One purpose of the fallback behavior negotiation is to provide network managers with a tool for alleviating this problem. Fallback methods should be used with extreme care, and SHOULD be coupled with event notification and monitoring."<p>Have you reviewed this IETF draft, and have any thoughts regarding implementation and potential changes to the draft’s proposals?
