Schmidt and Matthias Wählisch}, title = {{Discovery of Network-designated OSCORE-based Resolvers: Problem Statement}}, pagetotal = 12, year = 2025, month = jul, day = 7, abstract = {This document states problems when designing DNS SVCB records to discover endpoints that communicate over Object Security for Constrained RESTful Environments (OSCORE) {[}RFC8613{]}. As a consequence of learning about OSCORE, this discovery will allow a host to learn both CoAP servers and DNS over CoAP resolvers that use OSCORE to encrypt messages and Ephemeral Diffie-Hellman Over COSE (EDHOC) {[}RFC9528{]} for key exchange. Challenges arise because SVCB records are not meant to be used to exchange security contexts, which is required in OSCORE scenarios.}, }
