A Xxxxxxxxx-Xxxxxxx GKA The BD GKA protocol proceeds in two rounds (see Figure 6): First each player Pi broadcasts a public counterpart zi = gti of its contribution ti to the key. In the second round each Pi broadcasts gadget X[i−1,i,i+1] = gtiti+1 −ti−1 ti (which it can compute as X[i−1,i,i+1] = (zi+1/zi)ti ). Given the set of gadget values X[n,1,2], X[1,2,3], ..., X[n−1,n,1],
