The Chair took attendance.
The Antitrust Statement was read.
No changes to the agenda.
The minutes from the previous teleconference were approved and will be circulated to the public list.
Dean mentioned that the Final Guideline will be posted on the public web site and will ask the CA Security Council to update its link. The WG discussed about creating a separate timestamping document and whether the CSCWG should be re-chartered to include a timestamping certificates, associated with the id-kp-timeStamping EKU, in scope. Dean will discuss with Bruce to figure out what the plans are.
Ben talked about the need to recharter to make things as clean as possible. The existing guideline describes timestamping issues and if the WG was to make any edits to those parts, it should probably be better to re-Charter to specifically include the EKU of time stamping, as it relates to code signing and not necessarily try to create a separate time stamping working group. So, this would be like a first step and then if it was necessary, a separate time stamping working group could be chartered.
Arno mentioned that Europe and European CAs are issuing qualified timestamps for almost 15 years and there are well defined standards, policies by ETSI about timestamps.
Ryan also mentioned that this was discussed at the last F2F and more specifically during the S/MIME working group session where re-chartering was one of the topics. Google is not supportive of the Code Signing Working Group taking actions on time stamping. He noted that Time-stamping is not a code-signing issue but a broader problem which needs to be separate from code-signing. He also restated Arno’s comment about the European experience for 15 years and the fact that timestamps are actively being used along with document signing and archiving. There is no specific EKU for time stamping in relation only to code signing. The suggestion was to create a different Working Group with a separate Charter.
Dean also added that the Working Group is preparing an information sharing sheet, know who to contact, when to contact for code signing issues, malware etc.
Gordon asked if the solution to time stamping was the formation of a new Working Group and Dean replied that there are a couple of options to consider, one being that the WG doesn’t “touch” what’s in the current document and leave it the way it is.
Ryan also asked whether the WG adopted a document that provides guidance for time stamping that is outside the charter. Dean responded that the WG just adopted a document that already existed. He would take this discussion back to the WG to revisit.
Mike asked if Members would be interested to explore about updating the name “CA/Browser Forum” for the larger Forum especially since we have already added Code Signing Working Group, will add S/MIME and even Time Stamping Working Group.
Tim H was curious about a proposed name. Would be supportive of changing it. Dean mentioned that we have distinguished Certificate Consumers for each Working Group but if there are particular proposals that could better represent the whole Forum, we should discuss further.
Ryan added that the term Application Software Suppliers could be resurrected.
Arno and Dimitris considered the CA/B Forum a good marketing name which is widely recognizable. The “brand” name is a very important asset.
Dimitris added a topic for resurrecting the governance subcommittee as it was discussed at the last F2F. He reminded participants that he sent an e-mail to the management list a few weeks back and asked if there is interest in pursuing that. If not, Members would have to individually tackle some of the bylaws changes proposals and present them to the Forum.
Ryan mentioned that SubCommittees need to be formed via ballot so he repeated his proposal at the F2F meeting which was to distinguish the most pressing matters for governance and create a ballot. The question is whether we need a Forum subcommittee to work on those issues or if we should continue to discuss at the Forum’s plenary list. Ryan proposed we start discussing some of these issues on the Forum public list and see if we can make progress on priorities. Members can also have calls between themselves, if they need to discuss issues real time, without requiring the creation of a Subcommittee. This would help validate whether we should establish a Subcommittee and whether regular calls would be beneficial. One of the popular topics lately is the document version control, flexibility for the Chair or vice-Chair to make non-normative edits to the Final Guidelines, Forum Members and representatives where practically every Company representative has the full privileges for voting, participating, posting, etc. These are important issues that should be discussed and resolved. We have had governance discussions during the regular plenary forum teleconference in the past so we could try to continue and see where this leads to.
Dimitris agreed to that approach but also mentioned that the Google document with open issues has listed about 11 issues to be addressed so we need to prioritize. He will send a new message to the list to get some more feedback.
Dean reminded Members that plan to attend F2F 48 and 49 to signup and update the participant tables on the wiki so that the hosts can plan ahead.
