The specific context here is that I cited a 2024 paper as follows: "For the concrete KEMs, https://cr.yp.to/papers.html#safecurves reviews how X25519 avoids various security dangers of NIST P-256." Soatok Dreamseeker writes: > I would like to add that SafeCurves is woefully outdated. > https://eprint.iacr.org/2015/1060 > https://eprint.iacr.org/2014/043 I see no justification for this claim. Can you please quote a statement that you claim is rendered obsolete by https://eprint.iacr.org/2015/1060 and/or https://eprint.iacr.org/2014/043? ---D. J. Bernstein ===== NOTICES ===== IETF BCP 78, "Rights Contributors Provide to the IETF Trust", Section 5 (normative), "Rights in Contributions", provides a modification right "unless explicitly disallowed in the notices contained in a Contribution (in the form specified by the Legend Instructions)". The official language from IETF's "Legend Instructions" for the situation that "the Contributor does not wish to allow modifications nor to allow publication as an RFC" is as follows: "This document may not be modified, and derivative works of it may not be created, and it may not be published except as an Internet-Draft." <https://trustee.ietf.org/wp-content/uploads/Corrected-TLP-5.0-legal-provsions.pdf> The same language is used in, e.g., RFC 5831. The same language hereby applies to this document. This is not disclaiming or limiting the applicability of IETF policies; it is strictly following IETF policies. IESG claims that the "explicitly disallowed" provision in BCP 78 is limited to the examples in Section 3 in BCP 78. That is incorrect. BCP 78 states that Section 5, "Rights in Contributions", is normative, while Section 3, "Exposition of Why These Procedures Are the Way They Are", is informative. The opt-out provision in the normative text is clear, and cannot be limited by an informative section. BCP 78 does not give IESG any authority to issue changes or purported clarifications of the rules. Rationale for exercising the BCP 78 opt-out provision: I'm fine with redistribution of copies of this document. The issue is instead with modification, such as (1) IESG's May 2025 posting of an IESG-mangled version of an appeal that I had filed and (2) IETF management selling IETF mailing-list text to AI companies. This goes far beyond what copyright law allows as fair use (such as giving quotes for purposes of commentary). When I complained about the mangled document, the IETF Executive Director responded not by apologizing but instead by asserting that IETF management had the power to do whatever it wanted.
