Subject: WG Review: Using TLS in Applications (uta)
Date: Fri, 22 Nov 2013 09:35:54 -0800
From: The IESG<iesg-secretary@ietf.org>
Reply-To:ietf@ietf.org
To: IETF-Announce<ietf-announce@ietf.org>

A new IETF working group has been proposed in the Applications Area. The
IESG has not made any determination yet. The following draft charter was
submitted, and is provided for informational purposes only. Please send
your comments to the IESG mailing list (iesg at ietf.org) by 2013-12-02.

Using TLS in Applications (uta)
------------------------------------------------
Current Status: Proposed WG

Assigned Area Director:
   Barry Leiba<barryleiba@computer.org>


Charter:

There is a renewed and urgent interest in the IETF to increase the
security of transmissions over the Internet. Many application protocols
have defined methods for using TLS to authenticate the server (and
sometimes the client), and to encrypt the connection between the client
and server. However, there is a diversity of definitions and
requirements, and that diversity has caused confusion for application
developers and also has led to lack of interoperability or lack of
deployment. Implementers and deployers are faced with multiple security
issues in real-world usage of TLS, which currently does not preclude
insecure ciphers and modes of operation.

This WG has the following tasks:

- Update the definitions for using TLS over a set of representative
application protocols.  This includes communication with proxies, between
servers, and between peers, where appropriate, in addition to
client/server communication.

- Specify a set of best practices for TLS clients and servers, including
but not limited to recommended versions of TLS, using forward secrecy,
and one or more ciphersuites and extensions that are mandatory to
implement.

- Consider, and possibly define, a standard way for an application client
and server to use unauthenticated encryption through TLS when server
and/or client authentication cannot be achieved.

- Create a document that helps application protocol developers use TLS in
future application definitions.

The initial set of representative application protocols is SMTP, POP,
IMAP, XMPP, and HTTP 1.1. It is expected that other protocols that use
TLS might later be updated using the guidelines from this WG, and that
those updates will happen through other WGs or through individual
submissions.

The WG will make the fewest changes needed to achieve good interoperable
security for the applications using TLS.  No changes to TLS itself will
be made in this WG, and the WG will ensure that changes to current
versions of popular TLS libaries will not be required to conform to the
WG's specifications.

This WG will collaborate with other IETF WGs, in particular with the TLS
and DANE WGs.

Milestones:

I'm not that sure this, being essentially a work oriented towards best-prac=

 XXX with a potential application of DANE) Second, as a possibility to deli=

A new IETF working group has been proposed in the Applications Area. The
IESG has not made any determination yet. The following draft charter was
submitted, and is provided for informational purposes only. Please send
your comments to the IESG mailing list (iesg at <a href=3D"http://ietf.org"=
>ietf.org</a>) by 2013-12-02.

Using TLS in Applications (uta)
------------------------------------------------
Current Status: Proposed WG

Assigned Area Director:
  Barry Leiba <a class=3D"moz-txt-link-rfc2396E" href=3D"mailto:barryleiba@=
computer.org">&lt;barryleiba@computer.org&gt;</a>


Charter:

There is a renewed and urgent interest in the IETF to increase the
security of transmissions over the Internet. Many application protocols
have defined methods for using TLS to authenticate the server (and
sometimes the client), and to encrypt the connection between the client
and server. However, there is a diversity of definitions and
requirements, and that diversity has caused confusion for application
developers and also has led to lack of interoperability or lack of
deployment. Implementers and deployers are faced with multiple security
issues in real-world usage of TLS, which currently does not preclude
insecure ciphers and modes of operation.

This WG has the following tasks:

- Update the definitions for using TLS over a set of representative
application protocols.  This includes communication with proxies, between
servers, and between peers, where appropriate, in addition to
client/server communication.

- Specify a set of best practices for TLS clients and servers, including
but not limited to recommended versions of TLS, using forward secrecy,
and one or more ciphersuites and extensions that are mandatory to
implement.

- Consider, and possibly define, a standard way for an application client
and server to use unauthenticated encryption through TLS when server
and/or client authentication cannot be achieved.

- Create a document that helps application protocol developers use TLS in
future application definitions.

The initial set of representative application protocols is SMTP, POP,
IMAP, XMPP, and HTTP 1.1. It is expected that other protocols that use
TLS might later be updated using the guidelines from this WG, and that
those updates will happen through other WGs or through individual
submissions.

The WG will make the fewest changes needed to achieve good interoperable
security for the applications using TLS.  No changes to TLS itself will
be made in this WG, and the WG will ensure that changes to current
versions of popular TLS libaries will not be required to conform to the
WG's specifications.

This WG will collaborate with other IETF WGs, in particular with the TLS
and DANE WGs.

We are making progress on a well crafted problem statement.  Such things 
are very important, but need some meat here on the bones...

A number of conversations around the westbound interface.  What are the 
selectors passed to the KMP?  What is returned?  I will take a stab at 
it, and hoepfully I will get so good feedback (observation - some of you 
have done this for other KMP consumers like ESP):

 From SSE to KMP for setup request:


What type of security context:  Unicast or multicast.  And for 
multicast, a single SPI or SPI per transmittor?
What SSE format
What ciphersuite: Crypto-algo{&mode of operation], keysize
Other?

For rekey request:
SPI

Return from KMP:

SPI
KEYMAT (size, key, type)  Where type is unicast or group?


Of course if there is some specific copyable text from an existing API 
document, that would help a lot.
