The Research Of Controlled Quantum Teleportation With Identity Authentication

The basic principles of quantum mechanics are introduced into the traditional classicalcommunication to get quantum communication. Quantum communication is a disciplines branchof quantum information with brilliant research accomplishments, that its security is guaranteedby the basic principles of quantum mechanics.Quantum teleportation is one of the most striking research directions in the study ofquantum communication. Especially, controlled quantum teleportation makes significantprogress, that it is the most concrete proof of the quantum non-locality. Controlled quantumteleportation with trusted third party is safer than the typical quantum teleportation. Controlledquantum teleportation is used more widely in the field of quantum communication because itssafety.Since the general controlled quantum teleportation can not prevent the attack from forgedreceiver, we propose a controlled quantum teleportation scheme with identity authenticationbased on quantum engtanglement swapping in this paper. The scheme can prevent feignedreceiver to get any information. And we discuss the effectiveness and security of theimprovement scheme in detail.
