Baseline Requirements 1.1.7 and 1.1.8 Re-Posted

A couple of formatting errors were identified in the Baseline Requirements, and versions 1.1.7 and 1.1.8 have been replaced with corrected versions. Appendix A in versions prior to version 1.1.7 had parts of RSA public key exponent requirements as superscript. It should have read: “The CA SHALL confirm that the value of the public exponent is an odd number equal to 3 or more. Additionally, the public exponent SHOULD be in the range between 216+1 and 2256-1.” That is corrected in version 1.1.7. Also, versions 1.1.7 and 1.1.8 had combined the text at the end of section 11.1.4 as part of the title of section 11.2. That has been corrected in those two versions.

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 SMC015v2 was updated to remove an additional reference to the superceded ETSI EN 319 403.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).
