Benjamin Kaduk has entered the following ballot position for charter-ietf-sframe-00-02: No Objection When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/charter-ietf-sframe/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- This working group, however, will not specify the signaling required to configure SFrame encryption. In particular, considerations related to SIP or SDP are out of scope. This is because SFrame is intended to be applied as an additional layer on top of the base levels of protection that these protocols provide. [...] This text reads like it is saying that SIP and SDP provide "base levels of protection", which is not necessarily the case in the context of the protection that SFrame provides. It is anticipated that several use cases of SFrame will involve its use with keys derived from the MLS group key exchange protocol. The working group will define a mechanism for doing SFrame encryption using keys from MLS, including, for example, the derivation of SFrame keys per MLS epoch and per sender. It may be worth adding another sentence here to reiterate that just because MLS is complicated and may need special integration, that does not preclude using SFrame with other sources of key material.
