Ballot 143 – Formalization of Validation Working Group

Ballot 143 – Formalization of Validation Working Group

Reason

In order to address validation issues and inconsistencies in both the SSL Baseline Requirements and the EV Guidelines, the CAB Forum has held an informal working group previously referred to as the Extended Validation Working Group now known as the Validation Working Group, would like to modify its scope to include validation in the Baseline Requirements as well as the EV Guidelines.

Jeremy Rowley of DigiCert made the following motion, which was endorsed by Rich Smith of Comodo and Kirk Hall of TrendMicro.

Motion begins

The CA-Browser Forum formally establishes the Validation Working Group as an official working group of the CAB Forum, replacing the previous informal EV working group. The scope of this working group is to address issues arising under adopted CAB Forum standards related to the validation of certificate information and the inclusion of information in certificates.

Scope: The Validation Working Group will consider all matters relating to the validation and inclusion of information in certificates under adopted CAB Forum guidelines.

Deliverables: The Working Group shall produce one or more documents offering options to the Forum for validation within the scope defined above.

Motion Ends

The review period for this ballot shall commence at 2200 UTC on 5 Feb 2015, and will close at 2200 UTC on 11 Feb 2015. Unless the motion is withdrawn during the review period, the voting period will start immediately thereafter and will close at 2200 UTC on 18 Feb 2015. Votes must be cast by posting an on-list reply to this thread.

A vote in favor of the motion must indicate a clear ‘yes’ in the response. A vote against must indicate a clear ‘no’ in the response. A vote to abstain must indicate a clear ‘abstain’ in the response. Unclear responses will not be counted. The latest vote received from any representative of a voting member before the close of the voting period will be counted. Voting members are listed here: /about/membership/members/

In order for the motion to be adopted, two thirds or more of the votes cast by members in the CA category and greater than 50% of the votes cast by members in the browser category must be in favor. Quorum is currently nine (9) members– at least nine members must participate in the ballot, either by voting in favor, voting against, or abstaining.

S/MIME Requirements
v1.0.14 - Ballot SMC016 - May 5, 2026

This ballot maintains consistency between the S/MIME Baseline Requirements and the TLS Baseline Requirements with changes introduced by Ballots SC096 and SC097. Specifically, this ballot: Creates a carve-out of the logging requirements for DNSSEC specifically, stating these are not in scope. For audit purposes, change management logging is able to confirm if the appropriate controls are in effect or not. Sunsets all remaining use of SHA-1 signatures in Certificates and CRLs. It is noted that most uses of SHA-1 signatures are already deprecated by SC097. With this ballot, all unexpired Subordinate CA Certificates issuing S/MIME containing the SHA-1 signature algorithm must be revoked. This proposal does not prohibit the use of SHA-1 to generate issuerKeyHash or issuerNameHash values as currently required by RFC 5019. Includes minor formatting corrections.
