Wherein, service station is the equipment that can generate connection with terminal.
By taking car networking as an example, service station can be gas station or charging pile, because vehicle is needed to refuel or be charged, institute
With, using gas station or charging pile as service station, the trigger condition that group refueling or charging can be obtained as key, because
This, has higher convenience, and Vehicular charging or oiling are irregularly necessary and high frequency activity, by group refueling or are filled
The trigger condition that electricity is obtained as key can avoid being used for a long time same with the key between frequent updating vehicle and management platform
One key reduces the risk being decrypted.
Service station can also be the public transit facilities such as traffic lights or street lamp so that the process that vehicle travels on upper road
In, when by these public transit facilities, triggering key obtains, therefore, it may have higher convenience.
In system shown in Fig. 2, the distance between vehicle and service station, with the distance between service station and management platform
Compared to shorter, and because short-range possibility being trapped that communicates is relatively low, therefore, in the present embodiment, in vehicle and service station
Between information exchange carried out using non-quantum communication network, and between service station and management platform, using quantum communication network
Information exchange is carried out, to improve safety.
Fig. 3 is the flow that key shown in Fig. 2 obtains that system carries out key acquisition, i.e., a kind of disclosed in the embodiment of the present application
Key acquisition method includes the following steps:
S301:Quantum key collection is negotiated by quantum communication network between service station and management platform, quantum key collection includes
Quantum key corresponding with each terminal.
Specific key agreement mode may refer to the prior art, and which is not described herein again.
S302:The quantum key collection for negotiating to obtain is stored in local by service station.
S303:The quantum key collection for negotiating to obtain is stored in local by management platform.
Can be each terminal distribution pool of keys it should be noted that in management platform and service station, terminal it is close
Key pond is the independent memory space of the terminal, for storing the corresponding quantum key of the terminal, in order to manage.
It should be noted that the quantum key of service station and management platform storage can be by data mode or in a manner of photon
Storage.
S304:Whether service station monitoring terminal connect with service station, if so, S305 is executed, if not, periodically executing
S304。
Connection between terminal and service station can be that contact connects, for example, when group refueling, refueling nozzle is inserted into vehicle
Body, alternatively, when Vehicular charging, charging gun is inserted into car body.Connection between terminal and service station, or contactless company
It connects, for example, in the case where vehicle is not more than default value at a distance from fuel charger, vehicle passes through bluetooth and fuel charger data phase
Even.In another example service station is traffic lights, traffic lights is red light, and vehicle is during waiting for green light, between vehicle and traffic lights
It is connected by mobile communications network (including 2G, 3G, 4G or 5G mode).
S305:The information of terminal is issued into management platform using quantum communication network in service station.
In the present embodiment, the information of terminal is the unique identification information of instruction terminal, for example, distributing a vehicle for each car
Identification code, service station obtains the identification code of vehicle after being connected with vehicle, and issues management platform.
S306:Information of the service station according to terminal, verifies the legitimacy of terminal, if terminal is legal, executes S307, no
Then, terminate flow.
The purpose of S306 is, further increases the safety of key acquisition.Verify legitimacy specific implementation and
Algorithm may refer to the prior art, for example, existing authentication request and Authentication Response process, which is not described herein again.
It should be noted that S306 is optional step, can skip.
S307:Management platform sends key to service station using quantum communication network and indicates information.
It, can be to the key in each pool of keys for the accurately Corresponding matching quantum key on service station and management platform
Using numbering or tagging etc., modes are distinguish, and the identical key of management platform and service station is using identical or matched number
Or label.In the case where being in advance each cipher key number, key indicates that information can be the number of key.For example, vehicle
The number of 0001 corresponding key be respectively 0001-1,0001-2 ... ..0001-50, then key instruction information can be 0001-
2。
In storage address of the same key in management platform under the storage address unanimous circumstances in service station, also may be used
To use the storage address of key to indicate information as key.
S308:Service station is based on key and indicates information, and quantum key Y is obtained from the quantum key being locally stored.
S309:Service station uses non-quantum encryption policy X, and the quantum key Y of acquisition is encrypted, and obtains encryption letter
Breath.
S310:Service station uses non-quantum communication network, and encryption information is sent to terminal.
S311:Terminal uses the corresponding decryption policy of non-quantum encryption policy, is decrypted, obtains to the encryption information of reception
To quantum key Y.
S312:Quantum key Y is stored in local by terminal, and during subsequently being communicated with management platform, is made
It is encrypted with quantum key Y.
S313:The key obtained is destroyed in service station and/or key indicates information.
It should be noted that the encryption policy X used between service station and terminal and corresponding decryption policy, may be used
Conventional mode negotiates to determine, this will not be repeated here.
Optionally, terminal can feed back the message being properly received, service station is being received after receiving key to service station
To after the disappearance of successful reception, the key and/or key instruction information that service station obtains are destroyed, to further increase safety
Property.It should be noted that it refers to destroying the key retained in memory to destroy key.
The trunking that service station is obtained as terminal key is can be seen that from process shown in Fig. 3, is connected in terminal
Behind service station, the acquisition process of key is triggered, and key is obtained from management platform by quantum communication network and indicates information, also,
Innovatively regard the quantum key based on key instruction information instruction as data, using non-quantum (i.e. tradition) encryption policy into
After row encryption, it is transferred to terminal, there is higher safety.Again because short-range possibility being trapped that communicates is relatively low, because
This, the communications security between service station and terminal can also ensure.And because without being disposed between terminal and management platform
Quantum communication network, and quantum communication network need to be only disposed between relatively-stationary service station and management platform, therefore, have
Higher practicability and exploitativeness.
It should be noted that cipher key acquisition process shown in Fig. 3, can apply and be obtained for the first time after terminal accesses Internet of Things
The scene of key can also apply the scene in terminal more new key.
