This talk is about secret key distribution from correlations that violate Bell inequalities. A security proof can be obtained from the assumption that arbitrarily-fast signaling between different subsystems is impossible. This assumption is imposed at the level of the outcome probabilities given the choice of observables, therefore, the scheme remains secure in situations where the honest parties distrust their quantum apparatuses.
