Hi Opsec wg You may be aware that some of us have been looking at the potential impact of the deployment of Encrypted Client Hello (ECH), an extension to TLS1.3+. We are continuing to develop the draft, which is accessible at https://datatracker.ietf.org/doc/draft-campling-ech-deployment-considerations/. You will note that many of the issues that we have identified relate to various aspects of operational security in a variety of contexts.
We have been encouraged to share the draft with the Opsec working group to see if there is interest in the topic within the group, hence this post. I and at least one of my co-authors will be present in Yokohama for the IETF 116 meeting and will be happy to present the highlights of the draft if time is available on the wg agenda. Andrew
