Abstract:
In this paper, we present a quantum key distribution protocol with quantum authentication. The authentication process is based on the exchange of entangled pairs between a certification center and a communicator looking for being authenticated. The proposed scheme makes use of unitary quantum gates and the shared random number can be reused later for classical encryption after the authentication has succeeded.
