Hi all,
Many of you might not know me, but I’m part of RIPE’s software engineering team that takes care of RPKI.
I’ve been following this discussion closely and I've noticed some lack of clarity about our decision to duplicate our RPKI infrastructure.
So I think it’s important for us to tell a few things about our approach.
First what we have today in production:
- TA software (offline box)
- HSM for the TA (plus backups and spare parts)
- A few application servers running our RPKI software - I’ll call it RPKI-Core
- Redundant HSMs used by RPKI-Core
- RRDP publication service (cloud)
- Some rsync nodes (internal infra)
Something like the diagram below.
For testing environment we have practically the same infra.
And for public test (localcert) we use ‘soft' keys and no HSMs.
About the new AS0 TA, yes, we could simplify our infra.
One option would be to use ‘soft’ keys all around or use a HSM for TA only.
We could also use third-party software for TA, Core and publication service.
It crossed my mind, for a fraction of a second, to skip AS0 TA instances for our internal and/or public test environments.
But I don’t think we should treat it as a "second class citizen".
If we provide another TA, it’s worthy of receiving as much TLC as our production TA; meaning that it would also require the same (or similar) process around it as our production TA does. That includes keeping track of HSM card holders, defining a proper admin and operator quorum, scheduling periodical resigning sessions, etc…
I’m not here to advocate against nor in favour of AS0 TA.
But when discussing our implementation, this was our rationale to duplicate the infrastructure.
And that’s why it would cost us a lot to implement it.
Let me know you need more info about this subject.
Kind regards,
Thiago da Cruz
