Secret sharing splits a secret s into shares in such a way that k ≤ shares suffice to reconstruct s. Let ρi,j be the probability that shareholder i disclose their share to shareholder j, with 0 ≤ i, j < n. Given k ≤ ≤ n, to whom individuals should we hand shares, if we wish to minimize the probability that one of them reconstitutes s?
