can I just point out that the IPP project has no intension to try to solve
the overall security problems on the Internet, that should be left to the
numerous groups, in the IETF and elsewhere, already working on security.
What are trying to do is to evaluate which of the existing or emerging
security solutions could be used in combination with IPP. Authentication
schemes are likely to work in intranet environments now, and might work
over the global Internernet whenever the security groups have found a
I am also not in favour of inventing any specific security paradigm for
IPP. Hopefully the IPP will inspire some of the security folks to
concentrate on better security features to support it. For now, I think we
should limit ourselves to express requirements, in areas where there are no
suitable security solutions at hand.
