A free software conference in Sweden? That’s a rare one. Organized by the FSFE and Henrik Sandklef, it will be held on the 7-8 December 2007. I hope we’ll see more of this in Sweden. I’m proud to have been invited to talk about both GnuTLS and OpenID. I’m happy to see that there is a OpenMoko talk as well. If you want to participate, there is an early bird discount if you register now. If someone is going and would like to chat, drop me an email.


The TLS-AUTHZ document (protocol spec here) describes a mechanism to add support for authorization in the TLS protocol. The idea is part of a patent application, see the patent notification to the IETF. The protocol has a complicated history in the IETF. Right now a third last call is open to request feedback from the community. I’ve written about TLS-AUTHZ before.

RedPhoneSecurity is now trying to circumvent the IETF standardization process by trying to get the document published as an ‘experimental standard’. The document earlier failed to get consensus for publication on the standards track.

The responsible IETF Area Director, Tim Polk, argues that because there exists independent implementations, the community benefits from having the document published. The argument is silly because the only independent implementation is mine and I’m opposed to publication of the standard. Further, the document will remain accessible to anyone in the community with access to the Internet since it has been published as an Internet Draft. To clarify that we have no interest in a standard with patent claims, we have decided to remove the tls-authz implementation from GnuTLS. Together with the FSF we came up with the following statement which is part of the GnuTLS 2.0.2 release announcement:

** TLS authorization support removed.
This technique may be patented in the future, and it is not of crucial importance for the Internet community. After deliberation we have concluded that the best thing we can do in this situation is to encourage society not to adopt this technique. We have decided to lead the way with our own actions.

If you are concerned about having patented standards adopted by the IETF, now is a very good time to make your voice heard! The last call ends on October 23th. Please read about the issue, and familiarize yourself with the IETF process (RFC 2026, with updates related to patents in RFC 3989) and send your feedback to ietf@ietf.org.
