[caops-wg] Name Constraints - attempt at framing issues

[Von Welch]

After reading through this long, interesting conversation, I would  
like to suggest the following questions to frame this discussion. Von

1) What CAs do we wish to consider as potential issuers for our  
community? Is it just "Grid CAs" (by that I mean CA we can reasonably  
except to adhere to best practices as specified by GGF WGs) or do we  
want to also consider CAs that we have no reasonable expectation of  
being able to impact their policies or procedures (e.g. commercial  
CAs) as potential issuers for our community as well?

2) Do we believe that during normal operation the CAs indicated in  
the response to the first question have policy that will result in  
their issuing globally unique names and will reliably follow that  
policy?

3) If a CA is compromised, given currently implementations, this will  
result in the compromise of all certificates issued by that CA. An  
additional threat that a CA compromise would result in, is the  
compromise of privileges bound to certificates issued by other CAs,  
at relying parties that trust the compromised CA. Is this threat of  
concern to us?
