Abstract:
This paper shows that three cryptographic channels, secure channels (SC), anonymous channels (AC) and direction-indeterminable channels (DIC), are reduced to each other in the UC (universally composable) framework. We first define ideal functionalities for these channels, F/sub SC/, F/sub AC/ and F/sub DIC/. We then prove that a SC protocol UC-realizes F/sub SC/ in the F/sub DIC/-hybrid model, that a DIC protocol UC-realizes F/sub DIC/ in the F/sub AC/-hybrid model, and that a AC protocol UC-realizes F/sub AC/-hybrid model in the F/sub SC/-hybrid model.
