Ballot SC052v2: Specify CRL Validity Intervals in Seconds

Ballot SC-52 version 2: Specify CRL Validity Intervals in Seconds

This ballot expired before entering the voting period.

Purpose of Ballot: Similar to Ballot SC-31 which modified the specification of

OCSP validity periods to be in seconds, this ballot modifies the specification

of CRL validity periods to be in seconds to avoid confusion about exactly which

periods are valid and which are not. The ballot also specifies that other time

periods should be handled the same way, which has broader impacts throughout

the document.

These changes should not be interpreted as implying that missing a deadline by

a few seconds is any more or less important than it previously was. The

changes are merely intended to provide additional clarity and precision about

exactly where the deadlines are.

The following motion has been proposed by Tim Hollebeek of DigiCert and endorsed

by Trevoli Ponds-White of Amazon and Kati Davids of GoDaddy.

-MOTION BEGINS This ballot modifies the “Baseline Requirements for the Issuance and Management

of Publicly-Trusted Certificates” (“Baseline Requirements”), based on Version 1.8.0:

MODIFY the Baseline Requirements as specified in the following Redline:

S/MIME Requirements
v1.0.13 - Ballot SMC015v2 - Mar 28, 2026

This ballot introduces requirements that a CA or RA must follow to rely upon a Mobile Drivers License (mDL) to provide evidence for the authentication of individual identity. It allows the use of mDL that conform to ISO/IEC 18013-5 and which may be verified by the CA or RA in conformance with ISO/IEC 18013-7. The CA or RA shall only accept mDL from an Issuing Authority that is legally authorized by the relevant government or jurisdiction to issue driving licenses. The draft also aligns the subsections of 3.2.4.2 (Validation of individual identity) to correspond more closely with those in 3.2.4.1 (Attribute collection of individual identity). It also includes minor editorial corrections. SMC015v2 was updated to remove an additional reference to the superceded ETSI EN 319 403. This ballot is proposed by Stephen Davidson (DigiCert) and endorsed by Ben Wilson (Mozilla) and Scott Rea (eMudhra).
