Quantum key exchange and authentication is the core content of quantum secure communication, fully using quantum resources can effectively increase the confidentiality of communication. A quantum key swapping and authentication synchronous scheme based on principles of quantum entanglement swapping and teleportation and design principles of security protocols was proposed. This scheme is ingeniously designed, which makes full use of characters of quantum teleportation and quantum entanglement, enhances the security of communications, avoids the quantum eavesdropping, reduces the amplification of the density and avoids the classic channel＇s secu-rity threat.
