Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, implement below in conjunction with the present invention
Attached drawing in example, technical scheme in the embodiment of the invention is clearly and completely described.Obviously, described embodiment
Only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field
Art personnel all other embodiment obtained without creative labor belongs to the model that the present invention protects
It encloses.
Embodiment one
Referring to Fig. 1, the present embodiment provides a kind of WIFI of smart machine to match network method, smart machine includes bluetooth module
And WIFI module, this method comprises:
The communication connection of bluetooth module Yu terminal APP is established, to receive the encryption distribution information of terminal APP input；WIFI
Module parsing encryption distribution information, accesses wireless network access point after obtaining plaintext distribution information.
When it is implemented, bluetooth module and WIFI module preferably use the two-in-one mould group of WiFi bluetooth, to improve smart machine
Integrated level, naturally it is also possible to select independent WiFi mould group and independent bluetooth mould group, the two independent mould groups pass through string
Mouth carries out data communication, and in view of iOS and Android is to the compatibility of bluetooth mode, preferably bluetooth mould group uses BLE
(Bluetooth Low Energy) mode.Wherein, distribution information includes the SSID and password of wireless network access point.
The WIFI of smart machine provided in this embodiment matches in network method, when the communication connection of bluetooth module and terminal APP
Afterwards, terminal APP uses one-time pad technology secrecy distribution information, then by encryption distribution information by way of Bluetooth transmission
It is sent to bluetooth module, enables WIFI module using corresponding code key parsing encryption distribution information to obtain plaintext distribution letter
Breath, final WIFI module access wireless network access point according to plaintext distribution information request.As it can be seen that the present embodiment uses one time one
Secret skill art can ensure the safety of data transmission, be compared to the side for realizing safe distribution using encryption chip in the prior art
For case, the present embodiment can also reduce hardware cost while ensuring that distribution is safe.In addition, being compared to by WiFi skill
For art transmits distribution information, the present embodiment has higher data transmission efficiency using Bluetooth technology transmission distribution information and resists
Interference is stronger, and it is hereby ensured that match the high efficiency and stability of network process.
The communication connection of bluetooth module Yu terminal APP is established in above-described embodiment, is matched with receiving the encryption of terminal APP input
The method of net information includes:
In bluetooth module and terminal APP BOUND communication for the first time, negotiate to obtain main code key；When bluetooth module and terminal APP
When being again coupled to communication, negotiate to obtain work code key based on main code key；Terminal APP, which is received, by bluetooth module uses work code key
The distribution information of encryption.
When it is implemented, it is secret that actively master can be negotiated with terminal APP when bluetooth module detects that terminal APP belongs to and binding for the first time
Key, such as MaterKey can be based on negotiating work using main code key when secondary connect when bluetooth module is with terminal APP connection communication
Code key, such as WorkKey, so that terminal APP carries out encrypted transmission using the work secret key pair distribution information gone out when time connection negotiation,
The safety of the received encryption distribution information of bluetooth module is ensured.It should be noted that main code key be based on bluetooth module with
What the binding of terminal APP once generated, and the code key that works is to work as secondary connect with terminal APP based on bluetooth module to generate at random,
As long as that is bluetooth module and terminal APP reconnected after disconnecting all can negotiate to generate a job according to main code key again it is secret
Key, it is seen then that since work code key uses that a machine one is close and one-time pad technology generates, the transmission to distribution information
For have high safety.

Hold APP；Terminal APP restores main code key using root secret key K1 decryption APMB package N, while calling root secret key K2 to the main code key of reduction
Encryption generates APMB package N1 again, and APMB package N1 is back to bluetooth module；Bluetooth module calls root secret key K2 decrypted packet text
Part N1 restores main code key again；The main code key generated at random and the main code key consistency restored again are verified, if being verified
The main code key generated at random is defined as to the main code key for negotiating to obtain.
When it is implemented, root secret key K1, root secret key K2 and root secret key K3 are stored in advance in smart machine and terminal APP
In, it can be convenient bluetooth module and terminal APP to the calling of root secret key K1 and root secret key K2, during negotiating main code key,
By both sides repeatedly shake hands and encryption and decryption verifying, it is therefore an objective to legal identity certification is carried out to bluetooth module and terminal APP, and most
Negotiate to distribute to the main code key of both sides after being verified eventually.
Referring to Fig. 3, the method for negotiating to obtain work code key based on main code key in above-described embodiment includes:
Bluetooth module generates a character string R at random, and generates APMB package M using main code key encrypted characters string R and be sent to end
Hold APP；Terminal APP calls the APMB package M of main code key decryption encryption to restore character string R, then close to the character string R of reduction and root
Spoon K3 takes exclusive or processing to generate character string R1, finally calls main secret key pair character string R1 encryption to generate APMB package M1 again and is back to
Bluetooth module；Bluetooth module calls main code key decryption APMB package M1 to restore character string R1, while taking exclusive or again to character string R1
The final reduction character string R of processing；The character string R generated at random and the character string R consistency finally restored are verified, if being verified
The character string R generated at random is then defined as the work code key for negotiating to obtain.Wherein, exclusive or processing is that those skilled in the art are normal
With technological means, the present embodiment does not repeat them here this, in addition, be randomly generated due to character string R, bluetooth module and end
The work code key that negotiates of the end each reconnection of APP be it is inconsistent, that is, use one-time pad encryption technology, it can be ensured that distribution
The safety of information transmission, and both sides shake hands repeatedly and encryption and decryption verifying, it is therefore an objective to bluetooth module and terminal APP are closed
Method authentication, and finally negotiate to distribute to both sides' work code key after being verified.
Further, main code key and work code key are stored in simultaneously in smart machine and terminal APP, in order to bluetooth mould
The calling of block, WIFI module and terminal APP.Meanwhile after smart machine accesses wireless network access point, intelligence can be used and set
Standby identifier is registered beyond the clouds obtains DeviceID, to realize the backup of data beyond the clouds, and the above-mentioned main code key negotiated
It can also be used to cloud with work code key encrypt safely, reusability is preferable.
