Pedersen DKG implementation questions

[pool2win]

Couple of questions about Pedersen'd DKG:

1. Looking at

   cothority/dkg/pedersen/dkg.go

   Line 106 in e0c9afb

   errs := o.Broadcast(&Init{Wait: o.Wait})

   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.

2. 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 ?
