As the Internet of Things technology developed,network security has become a hotspot for communication security.Traditional encryption technology has certain technical vulnerabilities in the difficulty of decomposing large prime numbers and the security of long-distance communication.The quantum communication refers to the secure transmission of quantum information through quantum channels.Quantum communication technology is widely used,and related quantum technology's uncertainty principle,quantum non-cloning theorem and non-orthogonal state indistinguishability make the quantum communication technology completely safe.Using quantum related technologies to upgrade and cooperate in the application of the Internet of Things to improve efficiency.The research of quantum teleportation protocol based on the communication channel of the Internet of Things is the current research hotspot in information teleportation.Therefore,this paper mainly studies the quantum teleportation protocol based on the communication channel of the Internet of Things.The main research results are as follows:(1)Research on quantum teleportation of any two particles based on the sevenparticle cluster stateFirstly,for the problem of particle cluster dispersion and low efficiency in the communication process,a quantum teleportation protocol is proposed that uses the seven-particle entangled state as a communication channels to transmit any two particles.That the seven-particle cluster state consists of a five-particle cluster state and a Bell state achieves quantum teleportation under the control of a third party.Secondly,there are various methods,and the protocol uses fully Bell-state measurement and GHZ-state measurement alike.Finally,for the transmission security of the protocol,the security analysis of interception retransmission attack,entanglement measurement attack and participant attack are carried out to prove the security of the quantum channel transmission.(2)Research on the tripartite quantum teleportation based on the eight-particle cluster stateFirstly,in order to solve the problems of fewer particles in the cyclic transmission channel and less unknown particles,a three-party cyclic quantum teleportation protocol is proposed by using the eight-particle entangled state as the quantum entanglement channel.Secondly,for transferring more particles,a Controlled-NOT(C-NOT)operation is introduced to perform operation on unknown quantum states.The realization of quantum teleportation with only eight channel particles successfully transmitting six unknown quantum states.Finally,for the transmission security of the eight-particle entangled channel of the protocol,the quantum secure direct communication protocol is utilized to detect the circular three-party entangled channel and the security analysis of the internal and external attacks of the channel to ensure the security of the quantum channel.(3)Research on quantum teleportation protocol based on Internet of Things communication channelFirst,for addressing the security attacks and the short transmission distances in Io T communications,this protocol proposes the application of quantum teleportation in Io T communications.The quantum entanglement effect can ensure the absolute security of the communication channel and the absolute efficiency of the communication process.Secondly,the quantum repeater and wireless quantum network models are adopted to achieve the long-distance transmission research of the Internet of Things and the safety and reliability of data in transmission.Finally,for the transmission security of the Internet of Things communication channel and the authentication of the transmitting party in this scheme,the quantum key distribution protocol is used to perform security analysis and identity authentication on the communication process,which proved that the protocol transmission was secure.
