The updated security considerations in [1] > reference the IANA registry to emphasize this preference. > > > > - Key Share Reuse Prohibited in draft-ietf-tls-rfc8446bis: The WG recently > reached consensus to explicitly prohibit key share reuse across connections > in TLS 1.3. The new text changes the guidance from SHOULD NOT to a strict > MUST NOT. This resolves the concerns regarding static key reuse and its > associated privacy and forward-secrecy risks for ML-KEM. > > > > - Nadim updated the ProVerif model of TLS 1.3 to evaluate KEM and hybrid > KEM groups in TLS 1.3. This supports other results which show that KEMs are > secure when used in TLS 1.3 and that hybrid groups are secure even if one > of the components is compromised. > > > > - Liaisons: We received liaison statements from multiple SDOs including > O-RAN[2], IEEE 802.11[4] and from 3GPP[3] expressing support for the > publication of draft-ietf-tls-mlkem as an RFC as they rely on the IETF to > provide a stable normative reference. > > > > Please note that a third-party IPR disclosure exists [5] against this > document regarding patents related to the underlying ML-KEM algorithm. This > IPR declaration has not changed since the last WGLC. As a reminder, per BCP > 79, the IETF takes no stance on the validity of patent claims, and the > working group may decide to proceed with a technology despite IPR > disclosures if it decides that such use is warranted. > > > > Conduct Reminder: Given the heated nature of previous discussions on this > topic, participants are strongly reminded to adhere to the IETF Code of > Conduct (BCP 54) and the TLS WG's Mail List Procedures.
