Multiparty Secure Communication by Using Quantum Key Distribution Protocols

By using the order rearrangement of the single photon sequence and unitary transformations, a multiparty controlled quantum communication scheme for Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is presented. In this scheme, messages can only be recovered by the receivers with the permission of all controllers. It is shown that the security of messages transformation can be ensured and the performance of the proposed scheme enhances significantly since the collision can be avoided. In this paper, the authors design quantum authentication protocol and secure communication protocol by only using quantum channel. These protocols previously share a quantum key distribution to detect the dishonest node. The quantum Key distribution can promote authentication and secure communication for achieving higher liar detection probability.
