Hi, 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 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 SDSI/SPKI? * What are the main reasons that work on SDSI/SPKI stopped although much work was already done? tschuess Stefan -- Stefan Mink, Schlund+Partner AG (AS 8560) Primary key fingerprint: 389E 5DC9 751F A6EB B974 DC3F 7A1B CF62 F0D4 D2BA
