ENAME Workshop
A highly interactive workshop organized by the Internet Architecture Board raises important issues and generates ideas for significant follow-on work.
RFC 8188 builds on existing protocols to provide a new option for delivering trustworthy messages containing confidential information over the Internet.
HTTPS (HTTP over TLS) is possibly the mostwidely used security protocol in existence. HTTPS is a two-party protocol; it involves a single client and a single server. This aspect of the protocol limits the ways in which it can be used.
The recently published RFC 8188 provides protocol designers a new option for building multi-party protocols with HTTPS by defining a standardized format for encrypting HTTP message bodies. While this tool is less capable than other encryption formats, like CMS (RFC 5652) or JOSE (RFC 7516), it is designed for simplicity and ease-of-integration with existing HTTP semantics.
The WebPush protocol (RFC 8030) provides an example of the how the encrypted HTTP content coding could be used.
In WebPush, there are three parties: a user agent (in most cases this is a Web browser), an application server, and a push service. The push service is an HTTP server that has a special relationship with the user agent. The push service can wake a user agent from sleep and contact it even though it might be behind a firewall or NAT.
The application server uses the push service to send a push message to a user agent. The push service receives a message from the application server, and then forwards the contents of the push message to the user agent at the next opportunity. It is important here to recognize that the push service only forwards messages. It has no need to see or modify push messages. Both the user agent and the application server only communicate via the push service, but they both want some assurance that the push service cannot read or modify push messages. Nor do they want the push service to be able to create false push messages.
For example, an alerting service might use WebPush to deliver alerts to mobile devices without increased battery drain. Push message encryption ensures that these messages are trustworthy and allows the messages to contain confidential information.
The document draft-ietf-webpush-encryption, which was recently approved for publication as an RFC, describes how push messages can be encrypted using RFC 8188. The encrypted content coding ensures that the push service has access to the information it needs, such as URLs and HTTP header fields, but that the content of push messages is protected.
WebPush is available in some web browsers through the W3C Push API, which requires push message encryption.

Birds of a Feather sessions (BoFs) are initial, informal, in-person discussions about a particular the topic of interest to the IETF community. BoFs may or may not lead to establishing an IETF Working Group.
The IAOC is pleased to announce Vancouver, BC, Canada as the site for IETF 107 from March 21 - 27, 2020.
In early 2002, the RFC Editor revised their website look and feel to one that would stay essentially unchanged for the next 13 years. While the site has been very light-weight in terms of size and features, technology and user expectations have moved on and it was time for the site to change.
I am pleased to share that the IAOC has successfully concluded its search for an interim IETF Administrative Director.
