Pedersen DKG implementation questions #2512

Open pool2win opened 2 months ago

pool2win commented 2 months ago

Couple of questions about Pedersen'd DKG:

  1. Looking at https://github.com/dedis/cothority/blob/e0c9afbb847b070e1bda6f54561a4082b803db80/dkg/pedersen/dkg.go#L106 and then the SendToTreeNode implementation I am not clear if you are using private and reliable broadcast channels as required for Pedersen DKG.

We do need to send s_{ij} secretly from i to j.

  1. Have you covered the situation when a faulty process sends bad shares? Do we detect such failures?

That looks like a great question :) I think that this repository should be archived - what do you think, @pierluca ?
