Protocol Action: 'Oblivious HTTP' to Proposed Standard (draft-ietf-ohai-ohttp-09.txt)

[The IESG]

The IESG has approved the following document:
- 'Oblivious HTTP'
  (draft-ietf-ohai-ohttp-09.txt) as Proposed Standard

This document is the product of the Oblivious HTTP Application Intermediation
Working Group.

The IESG contact persons are Murray Kucherawy, Paul Wouters and Roman Danyliw.

A URL of this Internet-Draft is:
https://datatracker.ietf.org/doc/draft-ietf-ohai-ohttp/





Technical Summary

   This document describes a system for forwarding encrypted HTTP
   messages.  This allows a client to make multiple requests to an
   origin server without that server being able to link those requests
   to the client or to identify the requests as having come from the
   same client, while placing only limited trust in the nodes used to
   forward the messages.

Working Group Summary

There were a few topics that required in-depth discussion:

1. [Bad Key 
Configuration](https://github.com/ietf-wg-ohai/oblivious-http/issues/194): It
was resolved in https://github.com/ietf-wg-ohai/oblivious-http/pull/196
2. [Asynchronous Submission Use 
Case](https://github.com/ietf-wg-ohai/oblivious-http/issues/179): A new draft 
was created to address this use-case: 
https://datatracker.ietf.org/doc/draft-wood-ohai-unreliable-ohttp/
3. [Signals from server to proxy or vice 
versa](https://github.com/ietf-wg-ohai/oblivious-http/issues/114): being 
handled in a separate draft, and 
https://github.com/ietf-wg-ohai/oblivious-http/pull/113/files has text around 
proxy responsibilities

Apart from GitHub, these topics were either discussed on-list or during WG
session. Ultimately there was clear consensus on how to resolve these issues.

The draft reached broad agreement, as ascertained through both IETF session
participation and mailing list/GitHub discussion. Quite a few folks raised
[issues on 
GitHub](https://github.com/ietf-wg-ohai/oblivious-http/issues?q=is%3Aissue+is%3Aclosed).
Key decisions were surfaced on the mailing list.

Document Quality

There are implementations in [Rust](https://github.com/martinthomson/ohttp) and
[Go](https://github.com/chris-wood/ohttp-go). Apple iOS 16 includes OHTTP.
Cloudflare (https://github.com/cloudflare/app-relay) and Brave have
implementations as well.

This document interacts with HTTP WG and in general the SEC area. Participants
from the HTTP and security communities were actively involved in the
development of the document.

IETF 118 Registration Will Open on Tuesday, August 22, 2023

[IETF Secretariat]

Through circumstances beyond our control, we are still awaiting our Czech 
Republic VAT ID and have decided to postpone opening IETF 118 registration. We 
expect this to be resolved within the next couple of days, and we currently 
plan to open IETF 118 registration next Tuesday, August 22.

Last Call: (Privacy Pass Issuance Protocol) to Proposed Standard

[The IESG]

The IESG has received a request from the Privacy Pass WG (privacypass) to
consider the following document: - 'Privacy Pass Issuance Protocol'
   as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-c...@ietf.org mailing lists by 2023-08-31. Exceptionally, comments may
be sent to i...@ietf.org instead. In either case, please retain the beginning

Abstract


   This document specifies two variants of the two-message issuance
   protocol for Privacy Pass tokens: one that produces tokens that are
   privately verifiable using the issuance private key, and another that
   produces tokens that are publicly verifiable using the issuance
   public key.
