Abstract

Communication security with quantum key distribution has been one of the important features of quantum information theory. A novel concept of secured direct communication with no need of establishing any shared secret key has been the next step forward. The present paper presents a secured communication scheme with three particle GHZ state as the initial state where the receiver can simultaneously receive information from two parties. Possible eavesdropping has been examined.
