I reviewed this document as part of the Security Directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the Security Area Directors. Document authors, document editors, and WG chairs should treat these comments just like any other IETF Last Call comments. Document: draft-ietf-lwig-curve-representations-12 Reviewer: Russ Housley Review Date: 2020-08-27 IETF LC End Date: 2020-09-08 IESG Telechat date: unknown Thank you for addressing my earlier comments on -08. Summary: Ready Major Concerns: None Minor Concerns: None Nits: The Introduction talks about the traditional "short" Weierstrass curve model, and then most everywhere else talks about short-Weierstrass form. Can one phrase be used throughout? Question: Is support for these curves with in PKIX certificates (see RFC 5280 and RFC 5480) and CMS (see RFC 5652 and RFC 5753) as simple as assigning an object identifier for the two named curves? If so, can Section 10 be expanded to cover these too?
