Quantum Key Distribution and Management Terminal

QKDM-POL40 series integrate Quantum Key Distribution and key management in one enclosure, and have fully intellectual property rights. This series of products have the functions of quantum key distribution, storage, synchronization, relay, output, etc.

QKDM-POL40 devices are 19-inch 4U standard rackable enclosure, and suitable for the engine room environments, and mainly used in Metropolitan Area Network.

QKDM-POL40 can be divided into two types: QKDM-POL40A (Transmitting in simplex mode, Type-A) and QKDM-POL40B (Receiving in simplex mode, Type-B). Type-A and Type-B can be connected together to execute QKD and key management process, and provide quantum secret key, that cannot be decoded or eavesdropped, for the encryption service.

 QKD protocol: BB84 protocol with decoy-state method and polarization coding

 Quantum safe: Against attacks such as photon beam separation attack, light blinding attack and double counting attack

 Channel Adaption: Quantum channel polarization automatic correction

 Hardware implementation: FPGA implementation of QKD protocol & data processing algorithm

 High reliability platform: ATCA carrier-grade architecture, and redundant design with dual power supply, dual fans and etc

 Easy maintained facility: Blade structure and device-level log management

 Convenient expandability: System compatible with third party and provide diverse configuration

 Strict key randomness: Conform to the specification of the State Cryptography Administration

According to each facility's function, this series of products can be divided into two types: QKD-POL40A (Transmitting in simplex mode) and QKD-POL40B (Receiving in simplex mode)
Quantum key distribution in a metropolitan area. The products have been practically applied in thousands of miles of quantum communication networks so far
