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...

Unlike prior papers, it is assumed that the number of transmissions, the number of erroneous transmissions therein, and the direction of each transmission are predetermined. Besides, the size of the alphabet in each transmission is unequal and predefined. Using these transmissions, two nodes communicate...
