Ballot overview

  • Ballot SC067v3 proposes updates to the Baseline Requirements for the Issuance and Management of Publicly-Trusted TLS Server Certificates (TLS BRs) related to Multi-Perspective Issuance Corroboration (MPIC).
  • MPIC is described as performing domain validation and CAA checks from multiple Network Perspectives before certificate issuance.
  • The ballot states that not all validation methods in TLS BR Sections 3.2.2.4 and 3.2.2.5 will require using MPIC.

What the ballot changes (as reflected in the provided evidence)

  • Adds a requirement that CAs using specified validation methods must implement Multi-Perspective Issuance Corroboration as specified in TLS BR Section 3.2.2.9.
  • Defines corroboration conditions for a Network Perspective to count as corroborating:
    • For challenge-based validation, the Network Perspective must observe the same challenge information (Random Value or Request Token) as the Primary Network Perspective.
    • For IP address validation, the Network Perspective must observe the same IP address as the Primary Network Perspective.
    • For contact-based validation, the Network Perspective must observe the selected contact address used for domain validation observed by the Primary Network Perspective.
  • Includes an exception noted in the evidence for Onion Domain Names (MPIC requirement is stated as Except for Onion Domain Names in multiple places in the provided diff text).

Intellectual Property Rights (IPR) review process (as stated on the ballot page)

  • The ballot page includes an IPR review period notice for one Final Maintenance Guideline.
  • Members with Essential Claims to exclude must forward a written Notice to Exclude Essential Claims to the Working Group Chair and also submit a copy to the CA/B Forum public mailing list before the end of the Review Period.
