Tsvwg'ers We have finally posted a new revision of the encryption draft (below). This represents a compromise between different viewpoints and seeks to provide something that we can use to move forward. In particular, we're grateful for behind the scenes work by many people to form this text, and in particular for David's patience as the document shepherd. We extracted some text from section 5 into a new section 6. This seems (in retrospect) a useful place to bring together observations on eplicitly exposing information, rather than the OEM use-case (now the focus on section 5). In seeking useful words, we borrowed some throughts from Ted's IAB document (and specifically the security considerations of RFC 8558). We'd love to go further with this topic to discuss about what comes next, but as has been said before, this document is about considerations. I'm very conscious that this should have been published years ago, in preparation for the emergence of growing encyption. Alas, we did not have the foresight to do this. Hopefully this will be a basis to new thinking about how transport designs should evolve in a world of increased encryption. So, my question to the group: is it possible we can live with the current text and publish this? Gorry & Colin (with no-hats, as simple document editors) -------- Forwarded Message -------- Subject: New Version Notification for draft-ietf-tsvwg-transport-encrypt-14.txt Date: Fri, 03 Apr 2020 08:26:23 -0700 From: internet-drafts@ietf.org To: Colin Perkins <csp@csperkins.org>, Gorry Fairhurst <gorry@erg.abdn.ac.uk>, Godred Fairhurst <gorry@erg.abdn.ac.uk> A new version of I-D, draft-ietf-tsvwg-transport-encrypt-14.txt has been successfully submitted by Godred Fairhurst and posted to the IETF repository. Name: draft-ietf-tsvwg-transport-encrypt Revision: 14 Title: Considerations around Transport Header Confidentiality, Network Operations, and the Evolution of Internet Transport Protocols Document date: 2020-04-03 Group: tsvwg Pages: 51 URL: https://www.ietf.org/internet-drafts/draft-ietf-tsvwg-transport-encrypt-14.txt Status: https://datatracker.ietf.org/doc/draft-ietf-tsvwg-transport-encrypt/ Htmlized: https://tools.ietf.org/html/draft-ietf-tsvwg-transport-encrypt-14 Htmlized: https://datatracker.ietf.org/doc/html/draft-ietf-tsvwg-transport-encrypt Diff: https://www.ietf.org/rfcdiff?url2=draft-ietf-tsvwg-transport-encrypt-14 Abstract: To protect user data and privacy, Internet transport protocols have supported payload encryption and authentication for some time. Such encryption and authentication is now also starting to be applied to the transport protocol headers. This helps avoid transport protocol ossification by middleboxes, while also protecting metadata about the communication. Current operational practice in some networks inspect transport header information within the network, but this is no longer possible when those transport headers are encrypted. This document discusses the possible impact when network traffic uses a protocol with an encrypted transport header. It suggests issues to consider when designing new transport protocols or features. These considerations arise from concerns such as network operations, prevention of network ossification, enabling transport protocol evolution and respect for user privacy. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
