> some telegram rooms have tens of thousands of members
I'd say that at this point you can either:
* accept that there is no confidentiality anymore. It's just not realistic to have a "secret" group with that many members
* have the person who adds new members forward them the group key, and give up on key rotation
btw, I'm wondering how treeKEM manages malicious members when key rotation happens
- est31 7y ago> accept that there is no confidentiality anymore. It's just not realistic to have a "secret" group with that many members You do have a point, especially when it's a group where people are in their free time. However, if they are present for work they are less likely to leak information. Also, encryption should give a default level of privacy to build on.
- ccktlmazeltov 7y agoright, but how much do we want key rotation as a priority when a member leaves? What are the chances they're going to collude with whoever can see the traffic?
