I-D Action: draft-ietf-xmpp-websocket-05.txt


A New Internet-Draft is available from the on-line Internet-Drafts directories.
 This draft is a work item of the Extensible Messaging and Presence Protocol Working Group of the IETF.

        Title           : An XMPP Sub-protocol for WebSocket
        Authors         : Lance Stout
                          Jack Moffitt
                          Eric Cestari
	Filename        : draft-ietf-xmpp-websocket-05.txt
	Pages           : 14
	Date            : 2014-04-20

Abstract:
   This document defines a binding for the XMPP protocol over a
   WebSocket transport layer.  A WebSocket binding for XMPP provides
   higher performance than the current HTTP binding for XMPP.

The IETF datatracker status page for this draft is:
https://datatracker.ietf.org/doc/draft-ietf-xmpp-websocket/

There's also a htmlized version available at:
http://tools.ietf.org/html/draft-ietf-xmpp-websocket-05

A diff from the previous version is available at:

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.

XMPP over WebSocket schemas

As noted during the working group session last week, there's a small 
copy-and-paste error in the schema for the <open/> element: the 
see-other-uri attribute is allowed only on the <close/> element. Thus...

OLD

      <xs:element name='open'>
        <xs:complexType>
          <xs:simpleContent>

Comments on draft-alkemade-xmpp-iq-validation-00

(no hats)

Section 1: suggest s/it was found//

Before Section 4: suggest adding some examples in a new section.  Good
iq/response, spoofed response with different from (perhaps followed by
real response to make it clear), unexpected 'from' from the server

Section 4: suggest switching the order of 4.1 and 4.2.  current section
4.1 is an edge case, leading with the core mechanism is more understandible

Section 4.1: quote 6120 and 3920 directly if possible.

Section 4.2: we had lots of discussion over "unique".  We'll likely want
some flavor of that discussion in the final text.  For the MUST ignore
text, can the client log an error or notify the user?

Section 6: we'll likely want some security analysis here.

May a server perform this tracking too, and reject things that look like
attacks?

This doc is a good start.  I think we should adopt it into the working
group immediately.

comments on draft-miller-xmpp-e2e-06

Section 1
- This may be in the reqs draft, but seems worth stating here that some
end points for a given recipient may share keys, some may use different
keys, some may have no keys and some may not support encryption or
signature verification at all.

Section 3
- What should the sender do if some end points for a recipient indicate
lack of support for encryption?  Are error responses helpful independent
of confirmation that some end points support encryption?  Is the intent
for messages to only be sent to end points that advertise support?

- Why not include an end point's key in its info results and enable return
of the encrypted SMK (or even CEK) with the encrypted payload (to save a
round trip).  Given a single message could trigger a number of requests
for the SMK, the option to include the encrypted CEK in the payload may be
worthwhile.  Including the encrypted CEK would help with storage too.

- Why is the SID required to be unique for a {sender, recipient, SMK}
tuple?  This would allow for the same SID to be used to name every SMK
used with a recipient.  Suggest unique for each recipient (i.e., SMK's are
uniquely identified by recipient+SID for a given sender).

- Discuss how multiple recipients are handled

- s/optionallly/optionally

- It would be nice to have a summary of new state information the sender
and recipient are required to manage (like SMKs) and significant new
operations (like authorization of key requests where a given recipient may

message size

In the SAAG session just now, Daniel Kahn Gillmor just brought up an 
interesting issue about end-to-end message encryption in XMPP, and Matt 
Miller had an interesting reply. If we wanted to randomly change around 
the size of XMPP messages pre-encryption, we could easily add an XMPP 
extension to the payload and make the XML character data whatever size 
we please.

Fwd: JSJac + WebSocket

From my perspective to updated draft looks very good and promising. JSJaC (and MongooseIM) will be updated
soon to reflect the changes.
