[Cscwg-public] Ballot CSC-21: Signing Service Update

Tue Oct 17 19:06:19 UTC 2023

In the case where the CA is generating its own Key Pairs to issue itself code signing certificates, their obligations for key protection would be outlined in the sections pertaining to Subscriber Key Pair protection, even if the Private Key so happens to reside in a Signing Service that they run. I think this is fine but want to ensure there’s agreement on this interpretation.

Thoughts?

Thanks,

Corey

Hi Bruce,

I have a concern with the “Signing Service” definition:

“**Signing Service**: An organization that generates the Key Pair and securely manages the Private Key associated with a Subscriber's Code Signing Certificate.”

For subscribers that generate their own private keys and use these for signing (i.e., they manage them) I’m inclined to say that this would define them as a Signing Service.

Should we reword this to “An organization other than the Subscriber or any of its Affiliates, that generates the Key Pair and securely manages the Private Key associated with a Subscriber's Code Signing Certificate”?

Regards,

Martijn
