Naive simple idea:
1. Create one group key pair
2. Exchange the key pair with all group participants.
3. Let clients listen for this group public key
Pro:
- simple protocol
- better anonymity
Con:
- no forward secrecy
- initial noise on group creation
Too risky. The new key pair can leak without leaking the user's main key. Any disagreement in a group can expose the entire history of the group.
I‘m visiting Threema next Thursday. Tell me if you would like to be hooked up with someone.
Who is Threema?
The messenger company: https://threema.ch
Cool! If it is permitted to ask: Why are you going?
I‘ll bring the now bottled beer we brewed together on a company event.
Awesome! A colleague of mine is also brewing quite actively https://www.bunthaus.beer/die-biere/
