[Discission] Ballot SMC013: Enable PQC Algorithms for S/MIME

[Stephen Davidson]

Ballot SMC013: Enable PQC Algorithms for S/MIME

Summary: 

This ballot introduces specifications for the use of two post-quantum cryptography (PQC) algorithms, as standardized by the U.S. National Institute of Standards and Technology (NIST), in the S/MIME BR:

• ML-DSA, or Module-Lattice-Based Digital Signature Algorithm, a digital signature scheme; and
• ML-KEM, or Module-Lattice-Based Key-Encapsulation Mechanism, a key encapsulation mechanism.

The ballot specifies single-key/non-hybrid PQC certificates that do not rely upon pre-quantum algorithms.

The ballot is intended to enable experimentation by Certificate Issuers with PQC certificates; noting that additional requirements on the use of PQC may be imposed by Root programs.

This ballot is proposed by Stephen Davidson (DigiCert) and endorsed by Andreas Henschel (D-Trust) and Martijn Katerbarg (Sectigo).

— Motion Begins —

This ballot modifies the “Baseline Requirements for the Issuance and Management of Publicly-Trusted S/MIME Certificates” (“S/MIME Baseline Requirements”), based on Version 1.0.10.

MODIFY the Baseline Requirements as specified in the following Redline:

— Motion Ends —

This ballot proposes a Final Maintenance Guideline. The procedure for approval of this ballot is as follows:

Discussion (at least 7 days)

• Start time: July 2, 2025 at 18:00:00 UTC

[Karina Sirota Goodley]

Microsoft votes no on ballot SMC013.

 

Our concern is that once included, any subsequent changes—particularly those involving cryptographic algorithm requirements—would be significantly more difficult to implement due to the codified nature of the BRs.

 

Additionally, the Windows platform does not currently support post-quantum cryptography (PQC). There is no established environment within Windows itself to facilitate meaningful testing of third-party PQC certificates.

 

Importantly, this position does not prevent proponents from conducting testing or experimentation. However, we do not believe these certificates should be trusted by default or chain to a root that is broadly trusted at this time.

 

 

Best,

Karina
