Re: [CFRG] Second Call for adoption for draft-mattsson-cfrg-det-sigs-with-noise

[Michael StJohns <[e-mail]>]

Hi -

At this point I have no opinion on the technical content of the 
document, and IMHO that's the only thing the CFRG should be looking at 
when deciding to "adopt" a draft. The CFRG is a research group, not an 
IETF working group and "IPR" really shouldn't be a consideration - 
except of course for whether or not publication might be a copyright 
violation.  In terms of "encumbered" documents, it's possible, or even 
probable that someone will take a look at what's proposed, how it's 
encumbered, and figure out a method that accomplishes the solution 
without running afoul of IPR.

Leave the notion of IPR issues with respect to protocols to the IETF 
side of things.  Sure, no one may want to use it on the IETF side, but 
that's not the point of the IRTF - or shouldn't be.

The whole idea of the IRTF was to publish things quickly, and encourage 
robust discussions within the community.  To collaborate, to experiment, 
to revise, and repeat.  Ideas are supposed to be easy to publish, not 
subject to week and month long arguments about whether they meet a 
non-research criteria.

I'd be happy if the CFRG published 5 different signature schemes, each 
fault resistant and as secure as they can be made regardless of their 
IPR status.  Leave it to the IETF to eventually figure out which works 
for which protocols. It's quite possible the IPR rules or disclosures 
will change once the other side starts working on things.

The CFRG needs to avoid even the hint of a suggestion that they're 
attempting to pick winners in the crypto wars.

Later, Mike
