It should be noted that the Wi-Fi access point may be a device supporting IEEE 802.11 standard, such as a wireless router, a wireless repeater, a wireless network card, a mobile Wi-Fi, and other devices with built-in Wi-Fi modules.
As shown in fig. 2, an embodiment of the present application provides an information transmission method, including the following steps:
201. and the intelligent terminal establishes connection with the Wi-Fi access point.
When the intelligent terminal is connected with the Wi-Fi access point for the first time in the initial state, the intelligent terminal and the Wi-Fi access point are required to be awakened firstly, and then the intelligent terminal and the Wi-Fi access point are connected through the authentication connection process of a standard Wi-Fi protocol.
It should be noted that the main purpose of establishing connection between the intelligent terminal and the Wi-Fi access point in the initial state is that the intelligent terminal completes device registration and service registration at the Wi-Fi access point, so that when the intelligent terminal and the Wi-Fi access point are disconnected, the Wi-Fi access point can confirm the identity of the intelligent terminal according to registration information of the intelligent terminal at the Wi-Fi access point.
It should be noted that the intelligent terminal completes device registration and service registration at the Wi-Fi access point, that is, the intelligent terminal information and the service information of the intelligent terminal need to be recorded at the Wi-Fi access point side, where the service information indicates the type of information transmitted by the intelligent terminal to the Wi-Fi access point.
For example, when a smoke alarm (smart terminal) with a built-in Wi-Fi module is newly installed in a home, the user a first needs to establish a connection between the smoke alarm and a router (Wi-Fi access point) in the home.
202. The intelligent terminal sends first information to the Wi-Fi access point.
When the intelligent terminal is connected with the Wi-Fi access point in an initial state, namely when the intelligent terminal is connected with the Wi-Fi access point for the first time, the intelligent terminal sends first information to the Wi-Fi access point, wherein the first information comprises registration information used for registering intelligent terminal equipment and a public key of the intelligent terminal, the registration information can comprise form information of the intelligent terminal and a hardware address MAC of the intelligent terminal, the public key of the intelligent terminal is used for verifying the identity and the legality of the intelligent terminal through a subsequent Wi-Fi access point, and the form information of the intelligent terminal carries information such as the shape and the size of the intelligent terminal.
203. The Wi-Fi access point records the first information.
And when the Wi-Fi access point receives the first information, recording the first information, and finishing equipment registration and service registration of the intelligent terminal at the Wi-Fi access point, so that the Wi-Fi access point verifies the identity and the validity of the intelligent terminal according to the recorded first information after the intelligent terminal is disconnected with the Wi-Fi access point.
204. And the Wi-Fi access point sends the encryption key to the intelligent terminal.
The Wi-Fi access point can randomly generate an encryption key, the Wi-Fi access point can record the encryption key, then the encryption key is sent to the intelligent terminal, and after the intelligent terminal receives the encryption key, the encryption key is recorded, so that the state indicating information can be encrypted by the encryption key later.
205. And the intelligent terminal is disconnected with the Wi-Fi access point.
When the intelligent terminal and the Wi-Fi access point finish the steps 202 to 204 and no information is transmitted between the intelligent terminal and the Wi-Fi access point, the intelligent terminal and the Wi-Fi access point are disconnected, and the intelligent terminal enters a dormant state.
It should be noted that the smart terminal and the Wi-Fi access point may be automatically disconnected after the smart terminal and/or the Wi-Fi access point detect that the information transmission is completed, and may also be disconnected in other manners, for example, manually disconnected by a user, and a specific disconnection manner is not limited herein.
206. And the intelligent terminal wakes up the Wi-Fi module of the intelligent terminal.
After the intelligent terminal is disconnected from the Wi-Fi access point, when the intelligent terminal senses an event needing to be reported in a detection range and the Wi-Fi module is in a dormant state, the intelligent terminal can awaken the Wi-Fi module contained in the intelligent terminal to send information.
For example, when the user A is not at home, a child at home of the user A plays a fire, smoke generated by combustion exceeds a certain concentration, a smoke alarm installed at home of the user A is triggered, and the smoke alarm can wake up the Wi-Fi module of the smoke alarm.
207. And the intelligent terminal encrypts the state indication information according to the encryption key.
When the intelligent terminal senses an event needing to be reported in the detection range, the intelligent terminal encrypts the state indicating information by using the encryption key stored before to obtain the encrypted state indicating information, wherein the state indicating information corresponds to the sensed event needing to be reported.
For example, if the intelligent terminal is a smoke alarm, when the smoke alarm detects that the smoke concentration in the detection range exceeds a preset value, a reporting event is triggered, and at this time, the reporting event is that the smoke concentration exceeds the preset value.
208. And the intelligent terminal sends second information to the Wi-Fi access point.
After the Wi-Fi module contained in the intelligent terminal is awakened, the intelligent terminal sends second information to the Wi-Fi access point, wherein the second information comprises intelligent terminal information used for verifying equipment, a private key of the intelligent terminal and encrypted state indication information, and the intelligent terminal information comprises form information of the intelligent terminal and MAC of the intelligent terminal.
The second Information may be sent by a Wi-Fi module in the intelligent terminal through a Wi-Fi Prob broadcast frame, where the Wi-Fi Prob broadcast frame carries an Information Element (IE) field, and Information carried in the IE field is the second Information, where before sending the second Information, the intelligent terminal may add an extended Information Element IE by modifying the second Information, so that the extended IE carries intelligent terminal Information and status indication Information, where the modified IE field is a custom IE field, and one form of the custom IE field may be as follows, where the specific form is not limited here:
extension IE Vendor Specific
Element ID：221
Length：3～255
OUI：0x00-0xE0-0xFC
Data：Device Type+Version+Target MAC Address+Signature+Profile Info
·Device Type
Adding Signature field, identity authentication information of intelligent hardware, and using public key to make Signature check by router
Add Profile Info field, carrying Intelligent hardware State information
For example, after the smoke alarm wakes up the Wi-Fi module of the smoke alarm, a Wi-Fi Prob broadcast frame is sent through the Wi-Fi module, the Wi-Fi Prob broadcast frame carries a Wi-Fi AP management frame which modifies a Wi-Fi network, and the management frame carries the intelligent terminal information of the device, the private key of the device and the encrypted status indication information by adding an extended IE.
209. And the Wi-Fi access point determines whether the intelligent terminal is registered in the Wi-Fi access point and verifies the signature according to the received intelligent terminal information.
After the Wi-Fi access point receives second information sent by the intelligent terminal, the Wi-Fi access point compares intelligent terminal information in the obtained second information with registration information recorded when the intelligent terminal is connected with the Wi-Fi access point before, so as to determine the identity of the intelligent terminal, and checks and signs according to a private key in the obtained second information and a public key recorded when the intelligent terminal is connected with the Wi-Fi access point before, so as to confirm the validity of the intelligent hardware.
It should be noted that, when the Wi-Fi access point determines that the intelligent terminal is not registered at the Wi-Fi access point according to the received intelligent terminal information, the Wi-Fi access point does not acquire the status indication information in the second information; and when the Wi-Fi access point determines that the intelligent terminal is registered at the Wi-Fi access point terminal according to the received intelligent terminal information, but the verification signature does not pass, the Wi-Fi access point does not acquire the state indication information in the second information.
For example, when the router mentioned in step 201 authenticates the smoke alarm through the received intelligent terminal information and the previously stored registration information of the smoke alarm, and verifies the signature according to the stored public key and the received private key, the validity of the smoke alarm is confirmed
210. And the Wi-Fi access point decrypts the encrypted state indication information according to the encryption key.
And after the Wi-Fi access point receives the second information containing the encrypted state indicating information, the Wi-Fi access point confirms that the intelligent terminal is registered at the Wi-Fi access point, verifies the signature, and passes the validity authentication, the encrypted state indicating information is decrypted according to an encryption key generated when the Wi-Fi access point establishes connection with the intelligent terminal, and the decrypted state indicating information is obtained.
For example, after the router confirms the identity and the validity of the smoke alarm, the encrypted status indication information is decrypted by using the stored encryption key, and the status indication information is read.
211. And the Wi-Fi access point sends state change information to the user terminal according to the state indication information.
And after the Wi-Fi access point acquires the decrypted state indicating information, state change information is sent to the user terminal according to the state indicating information, so that the user terminal executes corresponding state change according to the state change information.
For example, after the router reads the decrypted status indication information, the router notifies a mobile phone carried by the user a according to the status indication information, and the mobile phone sends an alarm to prompt the user a that the smoke in the home exceeds a certain concentration.
