Abstract

The problem of simultaneously generating an asymmetric key pair with assistance of a helper is studied. In this setting, each of four terminals, i.e., a base station X0, two cellular nodes X1 and X2, and a helper X3, observes a component of correlated sources. The cellular nodes X1 and X2 wish to generate secret keys K1 and K2 with the base station X0, respectively, under the help of terminal X3. Both keys should be concealed from an eavesdropper that has access to the public discussion, while K2 is also required to be concealed from terminal X1. An outer bound on the key capacity region is derived. It is shown to be achievable under certain condition, and hence the key capacity region is characterized under such condition.
