I'm not closely involved with ROLL but I am working on devices using the CORE
work that would likely make use of and depend on this protocol. I have some
concerns about the practically of using ROLL given the IPR. My understanding of
the IPR is that one would be required to use certificates that are from an CA
license by Certicom.
My belief is that the many of the low cost devices that would want to implement
ROLL would be based on Linux implementation as that has become one of the most
widely used operating systems for low cost networking devices such as
residential routers. Given the optimal ways of integrating a protocol such as
this into the kernel, and the issues of likening such as this in GPL code, I
really wonder if the current IPR will be a major determent to deployment of
ROLL. It's not easy to search the archives and I easily could have missed
things but I can not find any significant discussion of it the WG could avoid
this IPR. There were a few emails in July but it did not seem like it really
hit this topic. I would have expected to see discussion on such topics as
David McGrews draft on Fundamental Elliptic Curve Cryptography Algorithms or
perhaps using RSA approaches. I think discussion about this IPR, and ways it
could be avoided, would be appropriate before approving this draft.
