5. Discussion

Stephen Davidson noted that there were no IPR essential claims on Ballot SMC07, which was adopted July 15. See https://cabforum.org/2024/05/24/ballot-smc07-align-logging-requirement-and-key-escrow-clarification/

Stephen also noted that Ballot SMC08 entered discussion period on July 15. See https://cabforum.org/2024/07/15/ballot-smc08-deprecate-legacy-generation-profiles-and-minor-updates/

The WG discussed Issue #251, which deals with two issues relating to the Network and Certificate System Security Requirements:

  1. NCSSR v2 applies after November 1, 2024, and
  2. For WebTrust audit periods starting after April 1, 2025 there is separate “seal” for NCSSR

Draft text has been proposed which will eventually move to ballot; see link at https://github.com/cabforum/smime/issues/251

The WG discussed the impact of the current TLS Multi-Perspective Issuance Corroboration ballot (aka MPIC, see https://github.com/cabforum/servercert/compare/c4a34fe2292022e0a04ba66b5a85df75907ac2a2..2dcf1a8fe5fc7b6a864b5767ab1db718bc447463) on S/MIME.

Stephen noted that the S/MIME BR refer to sections in the TLS BR that are modified to include MPIC. The WG discussed whether MPIC was as essential to S/MIME as TLS. There were no specific objections but the WG agreed to await the outcome of TLS ballot SC-067.

If TLS ballot SC-067 is successful, Stephen suggested that the SMCWG should be prepared to make decisions promptly as SC-067 includes specific implementation schedules. The WG also discussed whether TLS adoption of MPIC would already “cover” most S/MIME issuers, or if a separate adoption schedule should be considered. A review was suggested based on CCADB, and to send a note to the SMCWG list alerting S/MIME issuers to the MPIC discussion.

Stephen noted that if MPIC was adopted in the S/MIME BR, at a minimum, new definitions and a pointer to the new TLS 3.2.2.9 should be considered for the SBR. A draft text will be prepared.
