A cellular source model for key generation is proposed and studied, in which a central terminal χ0 wishes to generate K1 with terminal χ1 and K2 with terminal χ2, respectively, via public discussion. Each terminal observes a component of a correlated source sequence. The K1 is required to be concealed from an eavesdropper that has access to the public discussion, while the key K2 needs to be concealed from both the eavesdropper and terminal χ1. The key capacity region is established by showing that the cut-set upper bound is achievable.
