Quantum Authentication and Secure Communication Protocols

In the communication network, transmitting messages from source to destination may traverse several intermediate nodes. For a long period of time, multiple authentications and secure communications between the sender and the receiver are needed for us to transmit messages. In the classical field, authentication provides only conditional security and classical channel can not provide secure communication for liar detection. In the quantum field, multiple quantum entanglement pairs can be used for liar detection. In this paper, we 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.
