Does anyone know the status with respect to support for deniability / repudiation? I can't tell where they landed, and they seem to have deleted the paragraph from prior drafts that mostly left me more confused. https://datatracker.ietf.org/doc/html/draft-ietf-mls-archite... Previously, their designs had explicitly lacked this feature, and they said they actively didn't want it, citing "terrorism", resulting in arguments with Ian Goldberg, the developer of Off-the-Record messaging. https://datatracker.ietf.org/doc/html/draft-ietf-mls-archite... The arguments on the bug tracker about power imbalances were maybe a bit better, but I still personally believe this to be an important property (and one which clients need to fully embrace, allowing the ability to edit any part of the message history so easily anyone could figure out how to do it)

And it's still true today. I was considering implementing MLS myself, but decided against it because of this. https://github.com/mlswg/mls-architecture/blob/main/draft-ie...

In Messaging layer security: Secure and usable end-to-end encryption

Notably, this design lacks reputability, which for some reason they didn't even want (as it might be used by "terrorists"), which led to arguments with Ian Goldberg, the developer of Off-the-Record messaging. The arguments on the big tracker about power imbalances were maybe a bit better, but I still personally disagree. https://mailarchive.ietf.org/arch/msg/mls/ZJ4e78obXSdYWnxmsN... https://github.com/mlswg/mls-architecture/issues/50

In End-to-end encrypted messages need more than libsignal

saurik·Nov 15, 2020

I find the most interesting discussions surrounding this protocol are about whether or not it should support deniability / repudiation of messages. The Off-The-Record messaging people--including specifically Ian Goldberg--were unhappy that this was a non-goal, and the reasoning on the mailing list at the time was frustrating (that deniability can be used by "terrorists" to dodge investigations); but, I have also seen them have better arguments on their issue tracker (about power imbalances... though this argument was also controversial). https://mailarchive.ietf.org/arch/msg/mls/ZJ4e78obXSdYWnxmsN... https://github.com/mlswg/mls-architecture/issues/50
