RE: delta CRLs - NR assumptions



Title: Message
I concur James - there is no requirement and there should be no requirement that everyone receive the same results.  Just as emergency CRLs should be allowed by a CA that deems it necessary under a given circumstance.

> [Denis] "What about when they are two differents sets of evidence from the same relying party which are both valid (according to the way to use CRLs) but are contradictory ? "
[James] No problem.  The relying party chooses which ever set they want.     [The subscriber may know a different set of evidence was available, but how can they know that the relying party had it?  They cannot.]
> [Denis] "I see a problem here. If you use delta-CRls, full CRL only or OCSP (from the same CA) you do not necessarily get the same result. For a given signature policy, allowing only one means to obtain the revocation status would allow to make sure that everydody gets the same information."
[James] There is no requirement that everyone gets the same result.  NR is a statement by a subscriber such as "I agree to X if you can produce evidence that matches rules Y".  *Any* evidence matching the rules is sufficient, regardless of any other sets of evidence.
> [Denis] "In other words, it will be necessary to wait to make sure that a report of key compromise can be done. "
[James] Yes, for many applications.
