Description of the drawings
Fig. 1 is the system connection signal figure of invention；
Fig. 2 is that the implementation method of the present invention is schematically schemed；
Specific implementation mode
The embodiment of the present invention is described in detail below, but the present invention can be defined by the claims and cover it is a variety of
Different modes are implemented.
Shown in referring to Fig. 1 and Fig. 2, the present invention provides a kind of implementation method of quantum key cloud, including distribution quantum cryptography
Initial key；Establish secured communication channel；Distribute quantum key；Data encryption communication is carried out using quantum key.
Further, quantum cryptography initial key is published on terminal device by quantum key Cloud Server, the publication
Journey can be while continuously issue quantum cryptography initial key, as depicted in figs. 1 and 2, quantum key cloud to multiple terminals
Quantum cryptography initial key is sent to terminal 1 by server, and quantum cryptography initial key is sent to by quantum key Cloud Server
Terminal 2, these terminal devices include but not limited to mobile terminal, NB-loT terminals or other movements or fixed terminal, terminal
On equipment for obtaining quantum cryptography initial key include but not limited to be two-dimensional code scanning device, prestored quantum and added
The SIM card of close initial key, memory encrypted card, other storing initial keys card or built between quantum key Cloud Server
Vertical secured communication channel, when quantum cryptography initial key is to be transmitted by Quick Response Code, the carrier of Quick Response Code includes but unlimited
In the card for the Quick Response Code for being printed on quantum cryptography initial key or other can be obtained from quantum key Cloud Server it is initial close
The equipment of key and energy two-dimensional code display.
Quantum key Cloud Server by the quantum key stored on cloud and be sent to the quantum cryptography initial key of terminal into
Row exclusive or（XOR）Quantum key is sent to terminal by operation, and terminal preserves the quantum key as follow-up quantum key
The initial key of transmission is used for data encryption, repeats the above process, terminal, which is just preserved, to be largely used to quantum Cloud Server
Communication quantum key, to establishing quantum encryption communication channel between terminal and quantum Cloud Server.The process
Can be it is multiple be carried out at the same time or be carried out continuously, as depicted in figs. 1 and 2, the amount that quantum key Cloud Server will store on cloud
Sub-key and the quantum cryptography initial key for being sent to terminal 1 carry out exclusive or（XOR）Quantum key is sent to terminal 1 by operation,
The quantum key is preserved the initial key transmitted as follow-up quantum key or is used for data encryption by terminal 1, in repetition
Process is stated, terminal 1 just preserves the quantum key for being largely used to the communication with quantum Cloud Server, in terminal 1 and quantum
Quantum encryption communication channel is established between cloud.Quantum key Cloud Server is by the quantum key stored on cloud and is sent to end
The quantum cryptography initial key at end 2 carries out exclusive or（XOR）Quantum key is sent to terminal 2 by operation, and terminal 2 is by the quantum key
It preserves the initial key transmitted as follow-up quantum key or is used for data encryption, repeat the above process, terminal 2 just preserves
There is the quantum key being largely used to the communication of quantum Cloud Server, to be set up between terminal 2 and quantum Cloud Server
