Roll Call The Roll Call was taken. 2. Read Antitrust Statement The Antitrust/Compliance Statement was read. 3. Review Agenda Dean Coclin proposed a change in membership status (see below). 4.

Approval of New Members The declarations of the following were noted: Certificate Consumer: Zertificon Interested Party: Nathalie Weiler Their membership in the SMCWG was accepted by consensus. In addition, Dean Coclin clarified the status of current Associate Member MSC Trustgate.com Sdn Bhd as being eligible as a Certificate Issuer. A change in membership status was accepted by consensus. As such, the current membership of the SMCWG is: Certificate Issuers: Actalis, Asseco Data Systems (Certum), BuyPass, CFCA, Chunghwa Telecom, Comsign, DigiCert, D-TRUST, eMudhra, Entrust DataCard, GDCA, GlobalSign, HARICA, iTrusChina, MSC Trustgate.com, Sectigo, SHECA, SSC, SSL.com, SwissSign, TrustCor, Trustwave, TWCA, OISTE Foundation Certificate Consumers: Microsoft, Mozilla/Thunderbird, Zertificon Associate Members: ACAB Council, U.S. Federal PKI, WebTrust Interested Parties: Arno Fiedler, PSW, TeleTrusT, Vigil Security, Nathalie Weiler 6. Discussion of approach and deliverables It was agreed to begin a discussion of certificate profiles starting at the S/MIME end entity, working up the chain, in comparison to major requirements and standards. The worksheet currently includes aspects of standards from Mozilla, Gmail and the US Federal PKI (thanks for Wendy Brown’s assistance): https://docs.google.com/spreadsheets/d/1gEq-o4jU1FWvKBeMoncfmhAUemAgGuvVRSLQb7PedLU/edit?usp=sharing Certificate Issuers were asked to review their profiles for variance from these settings for discussion, with feedback preferred on the public list. Certificate Consumers were requested if there are technical requirements (must have/can’t have) imposed by their products or services on certificates. Ben Wilson was requested to check the profile against the Mozilla program requirements. Pertaining to Serial Number, it was discussed whether the requirement for 64 unpredictable bits was a legacy of the SHA1 deprecation or a necessary ongoing security feature. It is a requirement of the Mozilla Root Store Policy 5.2. Pertaining to Signature Algorithm, assistance was requested in either obtaining an English translation of BSI TR-03166 or in translating the text from German (with particular interest in the use of RSASSA-PSS). It was noted that ECDSA SHA-512 is not supported under Mozilla, with the question if the same applies to Thunderbird. Pertaining to Validity Period, there was discussion relating to the tradeoffs between shorter validity for crypto agility as championed in TLS, the use of tokens found in many S/MIME implementations, and in use cases such as email gateways. It was proposed that domain certificates would benefit from a separate profile. Discussion to be continued. 6. Any Other Business Again, WG members are encouraged to submit relevant standards and requirements to the public list. 7. Next call The next call will take place on September 2, 2020 at 11:00am Eastern Time. Adjourned
