Research On Efficient Quantum Hybrid Security Protocol Based On Network Coding

Quantum cryptography will be one of the important directions for research and development in cryptography in the future.Many principles of quantum mechanics provide security for quantum cryptography.However,the emergence of quantum computers has seriously threatened the traditional computing cryptosystem.Therefore,it is one of the important research topics in cryptography to find a quantum hybrid protocol technology that can efficiently transmit data and meet high security and save qubits in quantum transmission.Different from traditional cryptography,quantum cryptography changes the traditional information processing method to improve the efficiency of channel resistance to attacks and achieve the purpose of secure information transmission.However,quantum key distribution or quantum negotiation protocols are more complicated,and using quantum channels to transmit data is a waste of resources.Therefore,in the case where qubits are very precious,it is particularly important to combine network coding technology to minimize consumption.The communication part of the quantum hybrid security protocol mainly uses the quantum channel and quantum network coding methods,but the traditional storage or traditional channel transmission is still used when storing or negotiating the measurement base.The three-party quantum extended reflection distribution protocol in Chapter Three and the two-party network-encoded quantum key agreement protocol in Chapter Four are collectively referred to as hybrid quantum security protocols.Based on the above content of this paper,a quantum hybrid protocol based on network coding is researched and proposed to complete the communication.The following research results have been achieved:1.According to the characteristics of network coding,the complex quantum allocation technology is fused,and a quantum allocation protocol that is safe and effective and can save precious qubits is designed.Firstly,the defects in the general quantum distribution protocol are analyzed,and the characteristics of network coding are used.The sender sends some data to the receiver.The sender encodes the data,divides it into data packets,and sends a linear combination of the data packets through a quantum channel to produce a new type of quantum distribution protocol.This protocol implements the allocation process of the three-party quantum allocation protocol by "preparing once,receiving twice,and reflecting once".2.The two-party universal quantum key agreement protocol based on network coding,which also uses the characteristics of network coding,can not only increase the network communication capacity.At the same time,energy consumption is also being reduced.It can make up for the use of qubits in the quantum channel when transmitting data,and it will update the key required for the next session after each session is completed.This approach can ensure communication security.And this protocol requires less resources and a simple implementation structure.In the end,this article thinks and summarizes the future of information security.In the future,quantum technology will develop faster and better.Quantum technology will deeply integrate with existing technologies and coexist.
