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
