2、of information technology develops,the amount of data grows rapidly.However,at the same time,the risk of data being stolen or altered by attackers through the internet increases.The occurrence of digital information leaks has also resulted in an increasing demand for information security from countr

3、ies,organizations,and individuals.On the other hand,the continuous development of quantum computing technology poses unprecedented challenges to public-key cryptography systems based on large number factorization and discrete logarithms.Cryptography is the cornerstone of network security technology.

4、Quantum information security uses both quantum physics-based cryptography techniques(such as QKD,QT,and QSDC)and mathematics-based cryptography techniques(PQC).These new generation encryption technologies can be nested at different stages of the entire network,providing an additional layer of securi
