Re: [Pki-users] Dogtag autoenrollment from an embedded Linux device
Have you considered using a proxy between your embedded devices
and the PKI? With such a scheme you can pretty much do anything
you want and shield the devices and the PKI from changes to their
respective interfaces.
A solution such as this (that we deployed last year) works well
for a bio-tech firm that is embedding digital certificates into
"throw-away" consumables with embedded processors. The proxy
machine is a PC with custom a application responsible for
provisioning certificates to the embedded devices (based on
serial number, lot #, etc.), and bridges the devices to the PKI.

We have been testing pki-ra-1.2.0-2 on Fedora 11 via SSCEP as
a possible solution.
Our problem is that we need to be able to automatically deploy
certificates to thousands of embedded Linux devices, each
equipped with a common initial shared-secret or cert. Each needs
to be able to enroll, recover an initial individual cert based
on the system's serial number, and renew the cert... all over
a dial-up connection.
SSCEP seems to be falling out of the solution based on the
requirement for one-time PINs and manual approval of the requests.
Although the web interface works beautifully, we can't seem
to get SSCEP working.
We've looked at the CMCEnroll tool, but that requires Java which
is not part of the embedded software. This is an embedded flash
rom based system that does not have the memory available. Any
suggestions? I'd hate to have to cave-in to those that want a
Microsoft solution.
