Description
Technical Field
The invention relates to the technical field of internet, in particular to a distribution network information synchronization method, a distribution network information synchronization device and computer equipment.
Background
With the development of mobile internet and digital home technologies, more and more smart devices enter the home. The intelligent devices are usually accessed to a home wireless router through a Wi-Fi network, each different manufacturer of a device distribution network in an initial environment has a respective distribution network process, such as a common SmartConfig technology, an AP hotspot mode, bluetooth, NFC, an infrared sensor and the like, and all manufacturers are as follows: huashi, ali, millet, telecom, etc. are all proprietary protocol extensions that are customized based on these basic technologies. Different modes can solve the problem of initial distribution of equipment, but in order to ensure network security and prevent network information leakage, users can regularly modify Wi-Fi of the router in many cases, and if the Wi-Fi password of the home router is changed, wi-Fi equipment of all internet of things connected with the home router needs to independently perform Wi-Fi distribution. The traditional one-key distribution network (the equipment needing the distribution network is in a network hybrid mode, and sniffer (sniffer) performs air packet grabbing) or the hot point distribution network has inevitable defects, so that the distribution process of the equipment of the internet of things is very complicated and complex. Especially, under the condition that the number of the internet of things devices connected with the router is large, the process of the internet of things devices for re-distribution of the network is more complicated and complex.
In the existing scheme, after Wi-Fi information (also called distribution network information) of a router is changed, a reset instruction is actively sent to equipment, manual equipment resetting of a user is omitted, the equipment is in a state capable of being discovered, and although synchronization of the distribution network information is not completed, the user is omitted, and the user can be reminded of having equipment waiting for distribution network. Although this approach is consistent with the psychological expectations of the public, since most ordinary users believe that Wi-Fi passwords change and Wi-Fi devices do need to be reconfigured, this solution is clearly not convenient enough.
Meanwhile, the scheme is that before the Wi-Fi password of the router is changed, the changed Wi-Fi information is synchronized to all the devices through the intranet, then the router is changed into the real Wi-Fi, the devices continuously try to connect the new Wi-Fi, the devices do not connect in a certain trying period, and then the devices connect the original Wi-Fi. The scheme is a common scheme, the method avoids the process of the user for re-distributing the network, and is really convenient for the user. The scheme is that firstly, the Wi-Fi information of the modified router is synchronously sent to the terminal on the original connecting channel, then the terminal uses the new Wi-Fi information for connection, and meanwhile, the router modifies the new Wi-Fi information of the router. In the process, the router changes Wi-Fi while the terminal device changes Wi-Fi, the two change simultaneously, the risks are uncontrollable, one router is not successful, the two routers are in a mutually matched state, and if the router is successfully modified first, the device is switching Wi-Fi at the moment, the device is not connected with a new router Wi-Fi yet, and the router Wi-Fi is modified by a user for a short time, the device faces the risk that the device cannot be connected.
Meanwhile, according to the scheme, a router firstly acquires an MAC address of an intelligent terminal connected with the router, whether the router successfully changes the Wi-Fi password or not is judged, and if yes, the changed new Wi-Fi password is encrypted according to the MAC address; and sending the encrypted new Wi-Fi password to the intelligent terminal through a broadcast and multicast message. The scheme sends the Wi-Fi latest password through the broadcast or multicast message, the router and the intelligent terminal respectively carry out encryption and decryption through the MAC address, the Wi-Fi password is automatically updated, manual input of a user is not needed, and the operation is very convenient and humanized. In the scheme, a router can actively inform equipment after modifying Wi-Fi information, but the mode has an obvious defect, if a plurality of terminals in a home need to synchronously update the Wi-Fi information, the router needs to send different encrypted broadcast or multicast messages aiming at terminals with different MAC addresses, because MAC is a secret key, only corresponding MAC can decrypt, so that the trouble of a terminal equipment side is increased, specific broadcast or networking messages in a network need to be decrypted one by one, the decrypted messages can be abandoned, the equipment side also needs to start a network promiscuous mode, a sniffer (sniffer) performs air packet capturing, and the performance of the equipment side also can be influenced to a certain extent.
Meanwhile, the scheme is that when the intelligent terminal finds that the access password is wrong, the access password synchronization request information is loaded into a manufacturer specific information field of a detection request frame, and the detection request frame is broadcasted; the router side monitors the broadcast detection request frame and then responds; and the intelligent terminal receives a detection response frame replied by the wireless access point and acquires a new network access password from a manufacturer specific field of the detection response frame. In the scheme, the router does not inform equipment when changing Wi-Fi information, but the equipment side actively discovers that Wi-Fi connection is unavailable, then sends a broadcast detection request frame, and when the router monitors a broadcast request, the router responds to the updated Wi-Fi information to the equipment, although the method is feasible, the router needs to start a promiscuous mode to continuously monitor the broadcast information of the equipment in the network to filter a new request, and the router knows that the promiscuous mode needs the support of a chip and has certain influence on the Wi-Fi performance of the router, and if the Wi-Fi of the router is used by a user, the Wi-Fi performance is influenced; in addition, the device side finds that the password connection does not continuously send the broadcast detection request frame, if the Wi-Fi of the router of the same type of the neighboring home is just modified, it is highly probable that the device is connected with the router of the neighboring home, and certain risk exists.

Detailed Description
The distribution network information synchronization method provided by the embodiment of the invention can be applied to an internet of things system shown in fig. 1, and the system comprises the following steps: the intelligent router comprises an intelligent router, a plurality of intelligent devices and an operation terminal. The intelligent equipment and the operation terminal are connected with the intelligent router in a Wi-Fi mode. The intelligent router is provided with a formal access point and a default closed temporary access point, when the intelligent router receives a distribution network information updating request which is sent by an operation terminal and carries new distribution network information, the temporary access point is started, the intelligent equipment can be seamlessly and roamedly connected to the temporary access point, the intelligent router updates the distribution network information of the formal access point into the new distribution network information, the new distribution network information is sent to the intelligent equipment through the temporary access point after the updating is successful, the intelligent equipment is respectively disconnected from the temporary access point, and the new distribution network information and the formal access point are distributed to re-access the formal access point, so that the synchronization of the distribution network information on the intelligent equipment is automatically realized. In this embodiment, the operation terminal may be a smart phone, and the smart device may be a home-use internet of things-based smart device. It can be understood that, this embodiment is applicable to synchronization of distribution network information between the intelligent router and all the intelligent devices, and therefore, no specific limitation is imposed on the types of the intelligent devices.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present invention in its various embodiments. However, the technical solution claimed in the present invention can be implemented without these technical details and various changes and modifications based on the following embodiments.
In the following, the execution subject is taken as an intelligent router for example, specifically:
as shown in fig. 2, the distribution network information synchronization method of the present embodiment includes steps 201 to 204.
Step 201: and receiving a distribution network information updating request carrying new distribution network information.
Step 202: enabling the temporary access point for the smart device to roam to the temporary access point.
Step 203: and after the original distribution network information of the formal access point is updated to the new distribution network information, the new distribution network information is sent to the intelligent equipment through the temporary access point, so that the intelligent equipment can realize distribution network based on the new distribution network information and the formal access point.
Step 204: and closing the temporary access point after the intelligent equipment and the intelligent router finish the network distribution.
In particular, a typical intelligent router has a 2.4G access point and a 5G access point, both of which are user-visible access points. Meanwhile, a common intelligent router also has some hidden access points, which are closed by default and invisible to users. In this embodiment, the regular access point of the intelligent router may refer to the visible access point, and the temporary access point is the hidden access point that is closed by default. In this embodiment, after the intelligent device is powered on, the intelligent device is connected to the intelligent router through a private distribution network protocol, for example, a device conforming to the specification of the Andlink protocol for china mobile, and can be accessed to the intelligent router through the Andlink protocol.
Step 201 receives a distribution network information updating request carrying new distribution network information, where the distribution network information updating request may come from a terminal device such as a smart phone or a notebook computer. The user modifies the Wi-Fi name and the password (namely the network distribution information) of the formal access point (SSID 1) of the intelligent router through the APP, and notifies the router of the updated new network distribution information, so that the intelligent router receives the network distribution information updating request. Assuming that the initial Wi-Fi account password of SSID1 is (SSID 1, password 1) and the modified new distribution network information is (SSID 1-new, password 1-new), the new distribution network information is included in the distribution network information request and is sent to the intelligent router.
Step 202 is to enable the temporary access point for the intelligent device to roam and connect to the temporary access point, after receiving the distribution network information updating request, the intelligent router can immediately enable the temporary access point (SSID 2), and set the distribution network information (Wi-Fi account number, password, etc.) of SSID2 to (SSID 1, password 1), i.e. the distribution network information of SSID2 is the same as the original distribution network information of SSID 1.
Optionally, in this embodiment, the step 202 of enabling the temporary access point may further include: and increasing the beacon frame transmission frequency of the temporary access point to a preset value. Specifically, after SSID2 is enabled, the Beacon (Beacon) frame transmission frequency of SSID2 is increased, for example, the Beacon frame transmission frequency of SSID2 is set to 20 ms/time or 50 ms/time, and 1 to 2 beacons can be transmitted at a time, because the original Wi-Fi account password of the intelligent router still exists and the strength of the signal is further enhanced, each smart device originally connected to the intelligent router actively roams and seamlessly switches to a new SSID2 hotspot. It can be understood that, in this embodiment, no specific limitation is imposed on the sending mode of the Beacon frame of SSID2, as long as it is beneficial for the intelligent device to quickly and stably switch to the SSID2 hotspot.
In this embodiment, as an example and not by way of limitation, while the temporary access point is enabled, the original network configuration information of the formal access point may be updated to the new network configuration information, for example, the account password of SSID1 is updated to (SSID 1-new, password 1-new). Optionally, in this embodiment, if the operation of updating the original distribution network information of the formal access point to the new distribution network information fails, the distribution network information of the formal access point may be recovered, and the temporary access point may be closed. Namely, the intelligent router closes the SSID2, the intelligent device roams to the SSID1 hotspot again, the intelligent router recovers to the state before the change, and the subsequent process is terminated. Meanwhile, a message of failure of updating the distribution network information by the intelligent router can be sent to the operation terminal.
Optionally, in this embodiment, after the temporary access point is enabled, the method may further include: scanning information of the intelligent device which is in roaming connection with the temporary access point, wherein the information of the intelligent device comprises: a physical address (MAC) of the smart device; and comparing the information of the intelligent devices connected to the temporary access point with the recorded information of the intelligent devices connected to the formal access point to determine whether the recorded intelligent devices are all connected to the temporary access point. Specifically, the smart router may record the MAC and number of smart devices originally connected to SSID 1. After SSID2 is enabled, scanning the intelligent devices under SSID2 is started, and the MAC and the number of the intelligent devices roaming to SSID2 are obtained. By comparing the MAC and the number of the intelligent devices under SSID1 and SSID2, whether all the intelligent devices connected to SSID1 successfully roam to the SSID2 hotspot can be judged. The situation that the intelligent device which does not successfully roam to the SSID2 fails to synchronize the distribution network information occurs.
Optionally, in this embodiment, the step 203 of sending the new distribution network information to the smart device through the temporary access point may include: and symmetrically encrypting the new network configuration information by adopting an AES (advanced encryption standard) encryption algorithm and broadcasting the new network configuration information, wherein the intelligent equipment decrypts the new network configuration information by adopting a preset secret key. Specifically, the intelligent router may actively broadcast the synchronized new distribution network information (SSID 1-new, password 1-new) to each intelligent device through the connection channel of the SSID2 by means of a private distribution network protocol. In this embodiment, the new network-distribution information in the broadcast stage may be symmetrically encrypted by using a specific AES algorithm, and the key is a default value. After receiving the new distribution network information issued by the intelligent router, each intelligent device decrypts the new distribution network information by using a pre-agreed secret key, disconnects the connection with the SSID2 after the decryption is successful, then tries to connect with the SSID1 by using the new distribution network information, and can send a successful connection message to the intelligent router through unicast after the connection is successful.
Optionally, in this embodiment, closing the temporary access point after the intelligent device and the intelligent router complete the network distribution may include: and after the information of the intelligent equipment connected to the formal access point by the new network configuration information is compared with the information of the intelligent equipment connected to the formal access point by the original network configuration information, immediately closing the temporary access point. Wherein, the smart machine information includes: physical address of the smart device. Specifically, after receiving the message that the connection of the intelligent device is successful, the intelligent router can count the MAC of the successfully-connected intelligent device, compare the MAC of the successfully-connected intelligent device with the MAC of the intelligent device originally connected to the intelligent router, and under the condition that the comparison of the MAC information and the number of the intelligent devices is consistent, indicate that all the intelligent devices have successfully synchronized distribution network information, and at the moment, the intelligent router can immediately stop SSID2. If the MAC and the number of the intelligent equipment are not consistent after the intelligent router exceeds the preset synchronization time, the synchronization of part of the intelligent equipment fails, and the SSID2 is also stopped at the moment. The intelligent router can also send a message of synchronization success or failure to the operation terminal, so that the user can know the synchronization condition in time, and the user can perform necessary intervention according to the synchronization condition.
Compared with the prior art, the method and the device have the advantages that the temporary access point is started, the new network distribution information is sent to the intelligent equipment which roams to the temporary access point after the network distribution information of the formal access point is updated, so that the intelligent equipment can automatically distribute the network to re-access the formal access point based on the received new network distribution information, the synchronization of the network distribution information can be completed conveniently, the normal use of various intelligent equipment cannot be influenced during the synchronization, and the user experience can be improved. In addition, the embodiment broadcasts the new distribution network information in a symmetric encryption mode, so that the security is higher. In addition, intelligent router and smart machine all need not to open promiscuous mode to can not influence equipment performance. In addition, the embodiment of the invention does not need to modify hardware, and has wide applicability.
In the following, the execution subject is taken as an intelligent device for example, specifically:
as shown in fig. 3, the distribution network information synchronization method of this embodiment includes steps 301 to 303.
Step 301: and roaming the temporary access point connected to the intelligent router after the intelligent router enables the temporary access point.
When the intelligent router increases the Beacon frame sending frequency of the temporary access point, the intelligent device can be seamlessly and stably roamed and connected to the temporary access point.
Step 302: and receiving new distribution network information sent by the intelligent router through the temporary access point.
Optionally, when the new distribution network information is a ciphertext encrypted by a symmetric encryption algorithm, the intelligent terminal may decrypt the ciphertext by using a pre-agreed secret key, and the new distribution network information may be obtained after the decryption is successful.
Step 303: and distributing the network based on the new distribution network information and the formal access point.
Specifically, after receiving the new distribution network information, the intelligent device can disconnect the temporary access point and continuously try to connect the formal access point until the connection is successful.
Compared with the prior art, the method and the device have the advantages that the temporary access point is started, the new network distribution information is sent to the intelligent equipment which roams to the temporary access point after the network distribution information of the formal access point is updated, so that the intelligent equipment can automatically distribute the network to re-access the formal access point based on the received new network distribution information, the synchronization of the network distribution information can be completed conveniently, the normal use of various intelligent equipment cannot be influenced during the synchronization, and the user experience can be improved. In addition, the embodiment broadcasts the new distribution network information in a symmetrical encryption mode, and the safety is higher. In addition, the intelligent router and the intelligent equipment do not need to start a hybrid mode, and therefore the performance of the equipment is not affected.
