Research And Simulation Of Hierarchical Quantum Information Splitting Protocol Based On Multi-particle State

At present,most cryptography technologies are based on complex mathematical computing system to ensure security.However,in recent years,the proposed quantum algorithm has brought security risks to the traditional cryptography technology.In order to solve these problems,quantum cryptography technology with quantum mechanics as its security guarantee has been proposed.The principle of quantum cryptography has been deeply applied to communication technology,which is called quantum secure communication technology.Quantum information splitting protocol is one of the research hotspots in quantum secure communication technology.At present,quantum information splitting protocols have different schemes realized by different multi-particle entangled states,but there are few schemes which focus on hierarchical schemes.This topic mainly studies the hierarchical quantum information splitting protocol.Firstly,the deterministic hierarchical quantum information splitting protocols for arbitrary single quantum bit using four-particle entangled state and six-particle entangled state are studied respectively,and a general mode is proposed.Secondly,using two non-maximally entangled cluster states as quantum channels,we propose a probabilistic hierarchical quantum information splitting protocol for an arbitrary two-qubit state,and successfully extend the secret sharing of three agents to the sharing of multiple agents.In view of the existence of attackers in the protocol,this paper proposes a security detection method,and carries out security analysis of the proposed protocol under different attack modes.This paper also defines the calculation of communication efficiency of quantum information splitting protocol,and calculates the communication efficiency of the proposed protocol accordingly.Finally,this paper uses object-oriented language JAVA to simulate the quantum communication foundation,and then simulates the deterministic hierarchical quantum information splitting without attack,and simulates the proposed probabilistic hierarchical quantum information splitting protocol under different attack modes.The feasibility and security of the proposed protocol are verified experimentally.The proposed probabilistic hierarchical quantum information splitting protocol has more advantages than other probabilistic hierarchical quantum information splitting protocols.Firstly,the protocol achieves arbitrary information splitting of two quantum bits,whereas the previous probabilistic hierarchical quantum information splitting protocol achieves information splitting of single quantum bit;secondly,the protocol extends to the case of multiple agents,and the protocol can be extended.It is more expansive.In this paper,the quantum system is simulated reasonably by object-oriented language Java,and the simulation of quantum communication protocol on classical computer is realized,which provides a solution for the experimental verification of quantum communication protocol.
