Abstract: From the perspective of guaranteeing content security,a quantum key can enable secret communication with unconditional security.It can extremely improve the security of programs when applied to cryptographic applications.Considering that currently quantum key is seldom used in practice,this paper introduces the encryption methods of quantum keys and traditional keys for content security,and analyzes their characteristics in comparison,leading to a conclusion that the quantum key has more advantages than the traditional key.On this basis,this paper further introduces research on Quantum Key Distribution(QKD) network,and analyzes the characteristics of quantum key resources,as well as existing application scenarios and application methods.Finally,this paper discusses directions of future research,and gives reasonable suggestions for application of quantum key in communication protocols,software,hardware devices,and update of existing key resources.
