A New Internet-Draft is available from the on-line Internet-Drafts directories.
 This draft is a work item of the Hypertext Transfer Protocol Authentication Working Group of the IETF.

Title           : An Encoding Parameter for HTTP Basic Authentication
Author(s)       : Julian F. Reschke
Filename        : draft-ietf-httpauth-basicauth-enc-00.txt
Pages           : 10
Date            : 2013-05-16

Abstract:
   The "Basic" authentication scheme defined in RFC 2617 does not
   properly define how to treat non-ASCII characters.  This has lead to
   a situation where user agent implementations disagree, and servers
   make different assumptions based on the locales they are running in.
   There is little interoperability for the non-ASCII characters in the
   ISO-8859-1 character set, and even less interoperability for any
   characters beyond that.

   This document defines a backwards-compatible extension to "Basic",
   specifying the server's character encoding expectation, using a new
   authentication scheme parameter.

    <title>HOBA and draft-cavage signatures</title>
    <link>http://comments.gmane.org/gmane.ietf.http-auth/779</link>
    <description>&lt;pre&gt;
Hi,

So these two have a lot in common, but are in the end are a good
bit different I think. Sufficiently different that they probably
ought live separate lives as drafts probably, but maybe with bits
in common.

The common things:-

- HTTP Authentication schemes
- Both based on digital signatures for user authentication
- Similar or could-be-the-same syntax in lots of places
  which does offer the possibility of some library/code
  re-use that might help both

But there are very significant differences:

#1
- HOBA aims to displace passwords and no more
- draft-cavage wants to authenticate the user for payments as its
  main use-case

#2
= HOBA doesn't try to authenticate other parts of the HTTP request
  (we'll probably in -01 allow TLS channel bindings but that's not
  the same)
= draft-cavage does include other headers in the signature to
  authenticate those, possibly ultimately in a DKIM-like manner

#3
* HOBA has a key-pair-per-web-origin, at least as a default, with
  no HOBA-defined linkage between the public key and any identifier
  with well-defined semantics (applications can do that)
* draft-cavage I think wants just one or a few key pairs per user
  and probably with some well-defined semantics for identities
  associated with keys

#4
- HOBA has a built-in use of .well-known/hoba for registration
  etc.
- draft-cavage has very similar stuff in another spec but
  can't remember where that is:-)

Other notes:

- "Signature" as an HTTP authentication scheme seems way too
  broad - its hard to believe draft-cavage will be the only such
  ever (that's why I keep calling it draft-cavage above:-)
- I hate the idea that the same scheme supports both digital
  signatures and HMAC for user authentication - I think that's
  a bad error - just define two HTTP auth schemes if you really
  see a need for HMAC, or use the updated Digest that this WG
  is chartered to develop - encouraging more password verifier
  databases is just a bad plan (with all due respect to the
  other proposals this wg will develop:-)
- HOBA has this "demo of how to do hoba-js" aspect which isn't
  part of draft-cavage, us HOBA authors really like that:-)

Overall, I think (not very confidently, very much open to chatting
about it), were folks willing, it'd make sense to try define
common syntax and signature mechanism processing for these but
to progress them as separate HTTP authentication schemes that
both happen to use the digital signature mechanism but for
sufficiently different use-cases and security services that
they're better kept apart.

I'd be fine with this WG doing the work on draft-cavage if
that made sense. To get an HTTP authentication scheme
registered draft-cavage will have to pass IETF review in any
case, as that's the rule the httpbis WG have set for new
entries in that IANA registry. [1] So its not clear that
taking the W3C REC route will save the dravt-cavage
proponents much time, as their request for an IANA code
point will end up back here anyway. (Doing stuff in one
SDO is slow. Adding a 2nd SDO is a fine way to make
treacle look speedy:-)

But as I say, that's all fairly tentative so I wonder what
others think.

Cheers,
S.

    <title>First draft of HTTP Signatures published</title>
    <link>http://comments.gmane.org/gmane.ietf.http-auth/762</link>
    <description>&lt;pre&gt;The HTTP Signatures spec is a digital signature mechanism for the HTTP
protocol. It adds origin authentication, message integrity, and replay
resistance to HTTP requests. This is useful for any application that
currently depends on Basic, Digest, OAuth, or OAuth2 authentication when
performing RESTful HTTP calls.

Basically, if a client needs to prove to a server that it sent an
HTTP-based message, it can digitally sign that message. This spec
defines exactly how that happens.

This spec will be used by the Web Payments / PaySwarm / Web Keys work at
W3C. We're going to combine the public/private key-based signature
mechanism defined in HTTP Signatures with the public key infrastructure
system as defined in Web Keys to provide an easy way for nodes on the
Internet to verify their identity to other nodes on the Internet.

The first draft of this spec was just published via the Internet
Engineering Task Force (IETF) earlier today:

http://tools.ietf.org/html/draft-cavage-http-signatures-00

You can also find a datetime-stamped version of the spec here:

https://payswarm.com/specs/ED/http-signatures/2013-05-04/

The latest version of the spec can be found on the PaySwarm specs page:

    <title>Review of draft-melnikov-httpbis-scram-auth-00</title>
    <link>http://comments.gmane.org/gmane.ietf.http-auth/758</link>
    <description>&lt;pre&gt;First, my level-zero comments:

 - As most of you know by now, I think HTTP-layer authentication is a
bit of a dead end.  Consider Mozilla's BrowserID: an application-layer
authentication mechanism (i.e., authentication messages are POSTed).
But there is room for SCRAM here: in -to borrow a term from Kerberos-
pre-authentication of the user to the user's IdP.

   This comment applies to all proposals for authentication mechanisms
that fit into the existing HTTP authentication framework.

Next:

 - This SCRAM is not *the* SCRAM of RFC5802.  Perhaps it should have a
different name to distinguish the two.  In particular this SCRAM a)
adds various attributes such as "realm" and "sid" parameters, and b)
doesn't make use of the "-PLUS" suffix per-RFCs 5801 and 5802.  Nor
does this mechanism add the use of the SASL framework to HTTP -- it's
just an adaptation of RFC5802, not 5801.

   A list of all the differences between this mechanism and RFC5802
would be nice.  Is the authentication database for one usable with the
other?  See comments about the realm attribute below.

 - What's to be done with the "realm" attribute?  Should it be added
to the salt?  Or merely be used to route a SCRAM exchange to an IdP,
or to find the requisite authentication database?

 - What's the purpose of the "sid" attribute?  What can be done with it?

 - Why shouldn't the client name the desired server in its messages?
Then the exchange could be proxied to the named realm which could
authenticate the server doing the proxying.  That'd be nice.  No, I
think it'd have to be *required* if you want to have a realm for
federation purposes.

 - "pre-stored dictionary attack" is not how I'd phrase it.  More like
"pre-computation attack""using "rainbow tables"-- "a dictionary of
pre-computed hash results for a given one-way function and input
passwords".

 - Please remove the reference to "Registration of TLS server
end-point channel bindings"; RFC5929 should suffice.

 - A channel binding type should be required to be supported by
clients and servers, and it should be tls-server-end-point.

 - The security considerations section should mention the lack of
privacy protection for the client ID when not using TLS.

 - Section 7, third paragraph: no, no password-based authentication
mechanism protects against off-line dictionary attacks on stolen
password verifiers, not even ZKPPs.  I recommend striking this
sentence.

 - Section 7, fourth paragraph: how does salting help here?  Oh, by
ensuring that if the user uses the same password on multiple
sites/servers/realms then the verifiers will be different.

 - Section 7, 5th paragraph: how would one negotiate hashes in a
situation in which two SCRAM flavors are available, but both aren't
available for all users (because, e.g., the not all users have
re-enrolled).

 - Section 7, 6th paragraph, can you describe channel binding type
negotiation?  I thought there was none.

I'll save nits for some other time.

    <title>Reminder: Looking for reviewers</title>
    <link>http://comments.gmane.org/gmane.ietf.http-auth/755</link>
    <description>&lt;pre&gt;Hi Folks.

On Apris 10th, we issued a call for acceptance for several drafts. One has since been withdrawn. The remaining ones are (in no particular order):
 - draft-williams-http-rest-auth
 - draft-farrell-httpbis-hoba
 - draft-oiwa-http-mutualauth and draft-oiwa-http-auth-extension
 - draft-melnikov-httpbis-scram-auth

We already have 2-3 people who have committed to reviewing each of these drafts. Of course we value quality over quantity, but we would like to have some more. So this is a call for volunteers to review these drafts. You don't have to be a cryptographer to do these reviews (but if you are, that would be great!). We will ask reviewers to look at security, at implementation pitfalls, and at barriers to implementation in browsers, programmatic clients, and servers.  So if you have a good "feel" for security, we need you. And if you have experience in developing browsers or web applications, especially when such web applications require authentication and are high-value (think banks, online shopping), we really, really need you.

Please send email to the list, or to me directly.

Just to get things started, I will review rest-auth and SCRAM.

Thanks in advance

    <title>Biggest Fake Conference in Computer Science</title>
    <link>http://comments.gmane.org/gmane.ietf.http-auth/754</link>
    <description>&lt;pre&gt;Biggest Fake Conference in Computer Science


We are researchers from different parts of the world and conducted a study on  
the world’s biggest bogus computer science conference WORLDCOMP 
( http://sites.google.com/site/worlddump1 ) organized by Prof. Hamid Arabnia 
from University of Georgia, USA.


We submitted a fake paper to WORLDCOMP 2011 and again (the same paper 
with a modified title) to WORLDCOMP 2012. This paper had numerous 
fundamental mistakes. Sample statements from that paper include: 

(1). Binary logic is fuzzy logic and vice versa
(2). Pascal developed fuzzy logic
(3). Object oriented languages do not exhibit any polymorphism or inheritance
(4). TCP and IP are synonyms and are part of OSI model 
(5). Distributed systems deal with only one computer
(6). Laptop is an example for a super computer
(7). Operating system is an example for computer hardware


Also, our paper did not express any conceptual meaning.  However, it 
was accepted both the times without any modifications (and without 
any reviews) and we were invited to submit the final paper and a 
payment of $500+ fee to present the paper. We decided to use the 
fee for better purposes than making Prof. Hamid Arabnia (Chairman 
of WORLDCOMP) rich. After that, we received few reminders from 
WORLDCOMP to pay the fee but we never responded. 


We MUST say that you should look at the above website if you have any thoughts 
to submit a paper to WORLDCOMP.  DBLP and other indexing agencies have stopped 
indexing WORLDCOMP’s proceedings since 2011 due to its fakeness. See 
http://www.informatik.uni-trier.de/~ley/db/conf/icai/index.html for of one of the 
conferences of WORLDCOMP and notice that there is no listing after 2010. See Section 2 of
http://sites.google.com/site/dumpconf for comments from well-known researchers 
about WORLDCOMP. 


The status of your WORLDCOMP papers can be changed from scientific
to other (i.e., junk or non-technical) at any time. Better not to have a paper than 
having it in WORLDCOMP and spoil the resume and peace of mind forever!


Our study revealed that WORLDCOMP is a money making business, 
using University of Georgia mask, for Prof. Hamid Arabnia. He is throwing 
out a small chunk of that money (around 20 dollars per paper published 
in WORLDCOMP’s proceedings) to his puppet (Mr. Ashu Solo or A.M.G. Solo) 
who publicizes WORLDCOMP and also defends it at various forums, using 
fake/anonymous names. The puppet uses fake names and defames other conferences
to divert traffic to WORLDCOMP. He also makes anonymous phone calls and tries to 
threaten the critiques of WORLDCOMP (See Item 7 of Section 5 of above website). 
That is, the puppet does all his best to get a maximum number of papers published 
at WORLDCOMP to get more money into his (and Prof. Hamid Arabnia’s) pockets. 


Monte Carlo Resort (the venue of WORLDCOMP for more than 10 years, until 2012) has 
refused to provide the venue for WORLDCOMP’13 because of the fears of their image 
being tarnished due to WORLDCOMP’s fraudulent activities. That is why WORLDCOMP’13 
is taking place at a different resort. WORLDCOMP will not be held after 2013. 


The draft paper submission deadline is over but still there are no committee 
members, no reviewers, and there is no conference Chairman. The only contact 
details available on WORLDCOMP’s website is just an email address! 

Let us make a direct request to Prof. Hamid arabnia: publish all reviews for 
all the papers (after blocking identifiable details) since 2000 conference. Reveal 
the names and affiliations of all the reviewers (for each year) and how many 
papers each reviewer had reviewed on average. We also request him to look at 
the Open Challenge (Section 6) at https://sites.google.com/site/moneycomp1 


Sorry for posting to multiple lists. Spreading the word is the only way to stop 
this bogus conference. Please forward this message to other mailing lists and people. 


We are shocked with Prof. Hamid Arabnia and his puppet’s activities

    <description>&lt;pre&gt;Hi there,

below a few comments wrt to the base HTTP spec.

Editorial: the "b64token" ABNF production is now "token68".

Furthermore:

"The "token68" notation was introduced for compatibility with existing 
authentication schemes and can only be used once per 
challenge/credentials. New schemes thus ought to use the "auth-param" 
syntax instead, because otherwise future extensions will be impossible."

    <title>Web Keys and HTTP Signatures</title>
    <link>http://comments.gmane.org/gmane.ietf.http-auth/742</link>
    <description>&lt;pre&gt;My name is Manu Sporny. I'm the current Chair of the W3C RDFa WG, JSON
for Linking Data (JSON-LD) CG, and Web Payments CG. I am also an editor
of various W3C specs and member of the HTML WG and RDF WG.

There is a relatively new spec at W3C called Web Keys[1] that now
supports HTTP Signatures[2]. It is being worked on as a part of the Web
Payments[3] work. Specifically, the PaySwarm[4] specifications use Web
Keys and HTTP request signatures.

We'd like to coordinate with the IETF on this work to make sure we have
all parties interested in solving this problem involved in the work. We
would also like more eyes doing security audits[5] on the protocol.

For a high-level introduction to Web Keys, see the Mozilla Hacks article:

https://hacks.mozilla.org/2013/04/web-payments-with-payswarm-identity-part-1-of-3/

For a high-level introduction to the Web Payments work, look here:

http://blog.meritora.com/launch/

One of the first questions that came up in the IETF HTTP WG thread[5] on
the matter is why none of the other HTTP authentication schemes were
acceptable to the Web Payments group at W3C. Here is a quick run-down of
the reasoning:

HTTP Origin-Bound Authentication (HOBA)
http://tools.ietf.org/id/draft-farrell-httpbis-hoba-02.txt

We had considered signatures in the URL in the second approach to the
problem in the Web Keys spec. We eventually rejected the solution
because of limitations in the URL length in some browsers and because we
wanted the semantics of the HTTP headers to be able to be a part of the
digital signature. We also didn't want large signed messages being
dumped to the webserver logs (the request line is typically included).
So, while HOBA does solve the problem, it doesn't solve it in a way that
is acceptable to us.

HTTP Mutual Authentication
http://tools.ietf.org/html/draft-oiwa-http-mutualauth-12

Overkill for our purposes and requires multiple bounces back and forth
between the client and the server. Key exchange isn't required since
that's taken care of by the Web Keys PKI framework. We don't intend the
Web Keys HTTP signature protocol to be session-based, as a session-based
value can be built on top of HTTP signatures pretty easily.

HTTP Multilegged Auth
http://tools.ietf.org/id/draft-montenegro-httpbis-multilegged-auth-01.txt

Seems like overkill for our needs and is fairly specific to HTTP 2.0. We
wanted something that could work for HTTP 1.0. Multi-legged
authentication is something that we're not interested in solving using
HTTP Signatures. Putting state into the protocol is something we'd like
to avoid if possible.

HTTP Salted Challenge Response
http://tools.ietf.org/html/draft-melnikov-httpbis-scram-auth-00

Uses HMACs, doesn't use public key crypto, which is a requirement for
Web Keys and the Web Payments work.

HTTP REST Auth
http://tools.ietf.org/id/draft-williams-http-rest-auth-03.txt

This was the solution that seemed to be most interesting to the Web Keys
and Web Payments work. However, it requires quite a bit of state to be
remembered by the server (the Session URIs). Keeping the state of a
"session" around isn't desirable. We didn't want there to be a concept
of logging in and logging out of a website w/ the HTTP Signature stuff.
We'd rather that sessions are built on top of HTTP Signatures via a HTTP
header or cookie. Again, if we had to pick a back-up solution, HTTP REST
Auth seems like it might work for us, but we'd rather not use if we
don't have to.

I'll stop here and wait for feedback from the groups that are involved.
I am in contact with Stephen Farrell and a few other folks at IETF about
where best to coordinate the work.

    <link>http://comments.gmane.org/gmane.ietf.http-auth/731</link>
    <description>&lt;pre&gt;Hi folks

As per our charter, we are considering taking on draft-melnikov-httpbis-scran-auth to eventually publish as an experimental RFC. This is the call for acceptance. Please reply to this mail with a response such as:
 - yes, we should take this on, and I can be counted on to review it and contribute text in needed.
 - no, we should not take this on because…

The document will be accepted only if there are sufficient reviewers volunteering. Just to make it interesting, we also require that each document author review at least one other document.

Thanks

    <title>HTTP Digest Encoding</title>
    <link>http://comments.gmane.org/gmane.ietf.http-auth/723</link>
    <description>&lt;pre&gt;Hello,

Julian and I discussed this offline and we think that the mechanism defined in http://tools.ietf.org/html/draft-reschke-basicauth-enc-07 could be used to address the HTTP Digest encoding issue.
The following is some text that we think we could add to the above draft to address this issue.

---
In challenges, servers MAY use the "accept-charset" authentication parameter (case-insensitive) to express the character encoding they expect the user agent to use.

If the user agent supports the encoding indicated by the server, it SHOULD add the "accept-charset" parameter, with the value it received from the server, to the Proxy-Authenticate or WWW-Authenticate header fields it sends back to the server.

If the user agent does not support the encoding indicated by the server, it SHOULD add the "accept-charset" parameter to the Proxy-Authenticate or WWW-Authenticate header fields it sends back to the server, but the value in the parameter should be preceded by an exclamation point (!).

A user agent that does not follow this specification will ignore the parameter and will not include it in any response to the server.

When the server receives the new request with the Proxy-Authenticate or WWW-Authenticate header fields, it looks for the "accept-charset" parameter. If the "accept-charset" parameter is present, and its value matches the encoding the server sent to the client, the server will continue with its normal operation using the encoding it sent to the client. If, on the other hand, the "accept-charset" parameter value is preceded by an exclamation point (!), the server can immediately decline the request.

If the new request with the Proxy-Authenticate or WWW-Authenticate header fields does not have the "accept-charset" parameter, the server will know that it is dealing with a client that does not support this specification and should continue to perform its current operation.

The encoding indicated by the server impacts the way the server and the user agent concatenate the username-value, realm-value, and password when they calculate A1, as defined in section 3.2.2.2 of RFC2617.
---


What we are missing is information on how this currently works in practice, as this might help us either validate the above proposal or guide us to find the proper solution to the real world issue.
We would appreciate any feedback on the text above or any information on current practices.

Regards,
 Rifaat

    <title>Revising the "Basic" parts of RFC 2617</title>
    <link>http://comments.gmane.org/gmane.ietf.http-auth/710</link>
    <description>&lt;pre&gt;Hi there,

the above is in our charter, and I totally support that goal.

Apart from extracting the text into a standalone document that 
references HTTPbis-Part7, the following things should be done:

1) Rephrase the security considerations (for instance, with respect to 
"Basic" over https).

2) *Explain* the I18N issue.

3) Update references where needed.

4) Resolve errata (the one I'm aware of -- 
&amp;lt;http://www.rfc-editor.org/errata_search.php?rfc=2617&amp;amp;eid=1959&amp;gt; -- will 
be gone once we update the document to reference HTTPbis).

The charter also asks for

5) *fixing* the I18N issue.

That's non-trivial; see 
&amp;lt;http://greenbytes.de/tech/webdav/draft-reschke-basicauth-enc-07.html#faq&amp;gt;. 
That draft has a *proposal* for fixing the issue, but it's 
unimplemented. I do not believe we can claim it solves the I18N issue 
unless we can show that it works in practice (two servers, to UAs).

As such I would propose to:

a) Just do 1)..4)

b) Publish something like 
&amp;lt;http://greenbytes.de/tech/webdav/draft-reschke-basicauth-enc-07.html&amp;gt; 
as Experimental

c) Revisit the issue once we see implementations of b)

Best regards, Julian

    <title>improving HTTP authentication in user agents</title>
    <link>http://comments.gmane.org/gmane.ietf.http-auth/709</link>
    <description>&lt;pre&gt;Hi there,

no matter whether we tune/extend existing schemes, or try to deploy new 
schemes, we will have to consider limitations in existing user agents 
with respect to how WWW-Authenticate response header fields are parsed.

See test cases at: &amp;lt;http://greenbytes.de/tech/tc/httpauth/&amp;gt;

*All* of the major browsers get some of these tests wrong (*).

In the case of Firefox, it's because it doesn't have a *parser* for 
WWW-Authenticate; it just does a sub-string lookup.

So, please:

- review test cases,

- contribute new test cases,

- try to get some of the UAs fixed (at least Chromium and FF are Open 
Source...).

Best regards, Julian

(*) Konqueror isn't a "major" browser, but it *does* get things right.

regarding the charter[1] title, shouldn't that be "Hypertext Transfer Protocol Authentication"?

Or am I missing historical context here?

Working on WG chairs now :)
