I always thought "certification state" was some value that was
"approved" by some 3rd party certification organization.
And I thought "configuration state" might be something akin to what
you have derived below.
"Certification State" was something similar to what I included in a
previous email regarding FIPS certification. For "products" that are
certified, the certification is for a particular model number and
software version. If you're just certifying a software module (like
openssl), then you would provide the cert lab with a version and
either source or binary module, pre-configured to execute the cert
That's why I stressed that any "validation module" that wants to
verify the HCD_configuration_state needs to know "WHICH" certification
that this value reflects, and WHAT the correct value should be. For a
FIPS certification, this would be "FIPS 140-2" and "FF02CH001F00" (a
Example certifications might be:
Common Criteria (possibly multiple certifications)
ICSA (for firewall/security appliances)
"Works with Vista" or any of the half-dozen Microsoft logo certs you
can test against
My interpretations of these HCD_configuration and HCD_certification
states are based on what I think are the original rationale (going way
back) for these values...
Based on my understanding of "certification state", we would need to
support "one or more" certification states, depending upon how many
different types of certifications
are maintained by the device.
If my interpretation of the rationale for certification and
configuration states differs from the group, I'm sure someone will let
me know :)
