Abstract:

Quantum secure communication (QSC) based on quantum key distribution (QKD) is one of the promising solutions for improving the network information security in the future. In last decade, frontier research, demonstrational application, and network construction ofQSChave developed rapidly, the level of industrialization has been determined improved. Recently, the practical security issues of QSC system and network have caused widespread concern and discussion in academia, industry and public opinion. In this paper, the practical security issues of QSC systems and networks are analyzed, the prospects ofQSCapplicationand relevant strategies are discussed.

Key words: quantumkey distribution, quantumsecure communication, practical security, development prospects
