Abstract ：A new protocol for quantum secure communication with authentication is proposed. The proposed protocol has a higher capacity as each EPR pair can carry four classical bits by the XOR operation and an auxiliary photon. The security and efficiency are analyzed in detail and the major advantage of this protocol is that it is more efficient without losing security.
