Dogtag autoenrollment from an embedded Linux device
by Craig Zeller - SysAdmin
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.
