Hi,=20
I'm currently preparing courses about telecommunication security
architectures and protocols of which certificates are a main
building block for authentication and authorisation.
I'm presenting the PKI/PMI-models with X.509 as mainly used=20
architecture today and PGP as the distributed model.
I also want to present SDSI/SPKI but as far as I know, work in this
direction seems to have stopped: The IETF WG was closed and some
drafts weren't finished as RFCs. Nevertheless there are interesting
ideas which are worth showing in contrast to X.509.
I still have two open points which I couldn't resolve by searching
and reading:
* Are there other authorisation certificate standards besides=20
SDSI/SPKI?
* What are the main reasons that work on SDSI/SPKI stopped although
much work was already done?=20
tschuess
