How to compartment secrets

Gaëlle Candel, Rémi Géraud-Stewart, and David Naccache

Abstract

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 0i,j<n. Given kn, to whom individuals should we hand shares, if we wish to minimize the probability that one of them reconstitutes s?
