Focus on transforming quantum science technology from laboratory prototypes into practical commercial products
In 2019, it completed a new generation of stable high-speed commercial quantum communication system focusing on metropolitan area network, which is used to build a metropolitan communication network in the same city or neighboring city, used in defense and military secret communication, quantum government system, quantum financial security system, quantum power control system. And other important organizations involved in data security.
Quantum secure communication can be used to secure data transmission between data centers when performing data backup and business continuity between different data centers. The link encryption machine between the data centers can replace the key on demand through QKD to meet the high security data transmission requirements of enterprises and users.
Quantum secure communication can be used to protect the security of government and enterprise private network infrastructure and its services. Businesses or government agencies often require communication services to provide a high degree of confidentiality, integrity, and authenticity, and mandatory use of dedicated security systems.
Quantum secure communications can be used to protect data communication security in data acquisition and data acquisition (SCADA) systems in critical infrastructure. Critical infrastructure plays an important role in the normal operation of the social economy
QKD can be used to provide security services for communication between backbone nodes of a telecommunications network. At present, the telecommunications backbone network is mostly constructed by wavelength division multiplexing (WDM) technology, and the number of channels in the optical fiber is large. In addition to the already used traffic channels and the reserved guard and spare channels, there are generally remaining channels that can be used.
QKD can be used in the passive optical network (PON) of the telecommunication access network to ensure the communication security of the PON network. Through the QKD system, secure key distribution can be performed between optical line terminals (OLT) and optical network unit (ONU) end users in the PON network to realize encrypted transmission of ONU user data and provide new access to the telecommunication access network.
The network security protection of various mobile terminal users has become one of the hot issues currently concerned. Utilizing the unique advantages of QKD and the Key Distribution Center (KDC), the QKD-generated quantum key can be applied to the mobile terminal side to protect end-to-end and end-to-server communication security. Office, mobile work, mobile payment, Internet of Things and other scenarios are applied.
