RFC for Key Attestation

Mike from Entrust is trying to put together an RFC around Key Attestation. Information was circulated on the public list for anyone wanting to assist

There was a discussion on TPM 2.0 chips and similar if these are allowed or not. There’s consensus that as long as a device is FIPS 140-2 or 140-3 at the correct level, they are allowed to be used.

This will be clarified in the CSBRs in a future ballot.

Any Other Business

Next F2F is in 6 weeks. Ian mentioned that he plans on requesting a number of Microsoft employees working close with Code Signing to join the CSWG session as well as have some guest speakers during the F2F

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 SMC015v2 was updated to remove an additional reference to the superceded ETSI EN 319 403.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