How to Compartment Secrets
Résumé
Secret sharing splits a secret s into
$$\ell $$
shares in such a way that
$$k\le \ell $$
shares suffice to reconstruct s. Let
$$\rho _{i,j}$$
be the probability that shareholder i disclose their share to shareholder j, with
$$0 \le i,j < n$$
.Given
$$k \le \ell \le n$$
, to whom
$$\ell $$
individuals should we hand shares, if we wish to minimize the probability that one of them reconstitutes s?
