[0074] In order to reduce the risk of malicious monitoring of the WLAN network and improve the security of the WLAN network, an embodiment of the present application provides a network access method, device, electronic device and storage medium.

[0075] The terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0076] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings of the specification, it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application, and the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0077] With the rapid development of wireless communication technology, more and more public places will be configured with wireless local area network (WLAN), and in order to facilitate all users to access, wireless channel clear transmission is usually used, and then the users accessing the network are authenticated to ensure their security, such as the Potal page commonly used for authentication users.

[0078] However, the inventors have found through research that the above-mentioned method, since any user can access the WLAN network, although it cannot browse other pages without authentication, it can monitor the interaction data of other users, thereby infringing the privacy and security of users using the network.

[0079] In view of the above technical problems, the present application provides a network access method, device, electronic device and storage medium, which will be described below through specific embodiments.

[0080] Figure 1 An application scenario diagram of a network access method is provided for an embodiment of the present application, only the part related to the present application is shown for convenience of description, including but not limited to: terminal 10 and wireless access point (AP) 11.

[0081] The terminal 10 can include various handheld devices (such as a smart phone, a tablet computer, or an electronic book reader) having a wireless local area network function, a vehicle-mounted device, a wearable device, a computer, or a smart home device (such as a smart lighting device, a smart air conditioner, a smart curtain, a smart home appliance, and the like), and the specific type of the terminal 10 is not limited in the embodiments of the present application.

[0082] The terminal 10 can access any AP device in the WLAN network, and the terminal 10 searches for a communication service set identifier (SSID) published by the AP and inputs an encryption password of the corresponding SSID to implement the Internet connection and the online function.

[0083] The AP 11 is an access point of a wireless network, and is used to publish an encrypted communication SSID and an encrypted temporary SSID in the embodiments of the present application, to interact with the terminal 10, and to provide a communication SSID encryption password to the terminal 10, so that the terminal accesses the communication SSID to implement the online function.

[0084] It should be noted that the application scenario in the embodiments of the present application is used to more clearly illustrate the technical solutions in the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application, and is not limited to only the network access scenario. For other application scenarios and business applications, the technical solutions provided by the embodiments of the present application are also applicable to similar problems.

[0085] It should be noted that the network access method in the embodiments of the present application is applied to Figure 1 The application architecture shown in the figure is used for illustrative description.

[0086] After introducing the application scenario of the embodiments of the present application, the network access method provided by the present application is described in detail in the embodiments. Figure 2 A flowchart of a network access method provided by the embodiments of the present application, the method is applied to Figure 1 The AP, and the method includes the following steps.

[0087] In step 201, in response to a first connection request of any encrypted communication SSID published by a target AP and sent by any terminal, it is judged whether the connection password sent by the terminal in the first connection request for connecting the communication SSID is consistent with the current encryption password of the communication SSID.

[0088] In implementation, when the terminal connects to the AP of the target communication SSID, the terminal can receive any encrypted communication SSID published by the AP when the terminal enters the coverage of the wireless signal of the target AP. For example, the communication SSIDs published by the AP1 are SSID1, SSID2 and SSID3 respectively. In this case, the terminal can send a first connection request to any target communication SSID published by the AP1. For example, if the user wants to access the SSID1, the user can click the SSID1 on the SSID list displayed on the terminal and input the connection password to send the first connection request to the SSID1 published by the AP1. Then, it is determined whether the connection password for connecting the communication SSID sent by the terminal in the first connection request is consistent with the current encryption password of the communication SSID.

[0089] It should be noted that the connection password for connecting the communication SSID sent by the terminal in the first connection request can be the user password of the terminal user input when the terminal accesses the communication SSID of the AP for the first time, can be the encryption password of the SSID input by the terminal when the terminal accesses the communication SSID of the AP last time, or can be other password input by the terminal, such as a string of characters input by the user at will.

[0090] In step 202, if it is determined that the connection password is not consistent with the current encryption password of the communication SSID, the connection password is used as the user password of the terminal, and at least one username corresponding to the connection password is obtained.

[0091] In order to ensure network security, the encryption password of the communication SSID will be changed in a preset time or a preset period. Therefore, even if the terminal has accessed a communication SSID, when the terminal accesses the communication SSID again, the terminal can not be able to access the communication SSID because the encryption password of the communication SSID has been changed.

[0092] In implementation, if the terminal uses the user password as the connection password, or the terminal uses the encryption password of the SSID used when the terminal accesses the communication SSID last time as the connection password, or the terminal inputs other characters as the connection password to access the target communication SSID, the AP will determine that the connection password input by the terminal is not consistent with the current encryption password of the communication SSID. In this case, the AP cannot determine whether the connection password is the user password of the terminal or other characters input by the terminal at will. Therefore, the AP can use the connection password input by the terminal as the user password of the terminal, and try to find at least one username corresponding to the user password. It should be noted that the user password is set by the user according to the needs of the user. Because the user password is not unique, but the username is unique, any user password can correspond to one username or multiple usernames.

[0093] In implementation, the AP can search for the username corresponding to the connection password, which can be searched locally or in the server. For example, the terminal can be registered with a legal username and the user password corresponding to the username in the server. When in use, the AP can send the connection password input by the terminal to the server, and the server can search for the corresponding username based on the connection password. In this way, the storage space of the AP can be reduced.

[0094] In implementation, when the AP determines that the connection password input by the terminal is inconsistent with the current encryption password of the communication SSID, the AP can also feed back the prompt information of connection failure to the terminal. For example, the terminal can be sent "password error, please confirm and re-input". After the terminal receives the prompt information, if it is determined that the current sent connection password is not the user password of the terminal, the terminal can send a second connection request to the communication SSID with the user password as the connection password. In this way, only when the connection password sent by the terminal is the user password of the terminal, the AP can obtain the user password of the terminal based on the communication SSID, and then query the username to which the terminal belongs according to the user password.

[0095] In step 203, different temporary SSIDs are created based on the obtained usernames and connection passwords, which are non-public and have the connection password as the encryption password and the usernames as the SSID names.

[0096] In implementation, for example, the connection password input by the terminal is (12332188), and the query result of the username based on the connection password is shown in Table 1:

[0097] Table 1

[0098] User name User password User name 1 12332188 User name 2 12332188 User name 3 12332188

[0099] As shown in the above table, the AP queries a total of three usernames, which are username 1, username 2 and username 3. Then, the AP can create non-public temporary SSIDs according to the usernames and user passwords in the above table. The created temporary SSIDs are shown in Table 2:

[0100] Table 2

[0101] Serial number Temporary SSID name Encryption password SSIDa User name 1 12332188 SSIDb User name 2 12332188 SSIDc User name 3 12332188

[0102] In implementation, after receiving the prompt information, if the terminal determines that the current sent connection password is not the user password of the terminal, the terminal can send a second connection request to the communication SSID with the user password as the connection password. Of course, the terminal will receive the prompt information of connection failure again. At this time, the terminal can continuously attempt to access the temporary SSIDs with the username as the SSID name of the temporary SSID and the user password as the encryption password of the temporary SSID, until the AP creates the non-public temporary SSIDs, and then the terminal accesses successfully.

[0103] For example, if the terminal's username is username1 and the password is (12332188), the terminal sends a second connection request to the communication SSID using (12332188) as the connection password. After receiving a connection failure message, the terminal will continuously try to access the temporary SSID using username1 as the SSID name and (12332188) as the encrypted password for the temporary SSID, until the AP creates three non-public temporary SSIDs as shown in Table 2 above based on (12332188), at which point the terminal will successfully connect.

[0104] In step 204, the target temporary SSID for terminal access is determined, and a request to obtain the encryption password of the communication SSID is received from the terminal. The encryption password of the target temporary SSID is the terminal's user password, and the SSID name is the terminal's username.

[0105] In specific implementation, the target temporary SSID for terminal access can be determined by responding to a third connection request sent by the terminal to the temporary SSID. The third connection request includes the terminal's username and the user password sent by the terminal. If it is determined that the username of the third connection request matches the SSID name of any created temporary SSID, and the user password of the third connection request matches the encrypted password of the temporary SSID, then the target temporary SSID for terminal access is determined.

[0106] For example, taking the non-public temporary SSID created by the AP as shown in Table 2 above, in the third connection request sent by the terminal to the temporary SSID, the SSID name is username1 and the encrypted password is (12332188). When the terminal receives the access success prompt message, the username is username1 and the password is (12332188). For example, if the terminal's identification information is displayed in the list of terminals currently connected to SSIDa on the AP side, then it is determined that the terminal is connected to the target temporary SSID.

[0107] In specific implementation, after determining the temporary SSID used by the terminal to access the target, the terminal can receive a request to obtain the encrypted password of the communication SSID. For example, after the terminal successfully accesses the target temporary SSID, it can automatically send a request to obtain the encrypted password of the communication SSID, or click on the communication SSID again to trigger the request to obtain the encrypted password of the communication SSID. This application does not limit this.

[0108] In step 205, when it is determined that the password sending conditions are met, the encrypted password of the communication SSID is sent to the terminal so that the terminal can access the communication SSID using the encrypted password of the communication SSID.

[0109] The first connection request further includes a media access control (Media Access Control Address, MAC) address of the terminal, and the MAC address can be used to determine the uniqueness of the terminal. After receiving the request for obtaining the encrypted password of the communication SSID sent by the terminal, if the AP determines that the MAC address of the terminal sending the request for obtaining the encrypted password is consistent with the MAC address of the terminal, it is determined that the password sending condition is met, and the encrypted password of the communication SSID is sent to the terminal, so that the terminal accesses the communication SSID by using the encrypted password of the communication SSID.

[0110] In specific implementation, based on the obtained usernames and connection passwords, different temporary SSIDs with the connection passwords as the encrypted passwords and the usernames as the SSID names are respectively created, and then the terminal access situations of the temporary SSIDs can be monitored. If it is determined that no terminal accesses any temporary SSID within a first preset time length, the temporary SSID is closed; or if it is determined that a terminal accesses any temporary SSID, and it is determined that the terminal does not access the corresponding communication SSID within a second preset time length, the temporary SSID is closed.

[0111] In this way, the security of the temporary SSID network can be ensured, the risk of the temporary SSID being monitored for a long time without terminal access is reduced, network resources are saved, and invalid occupation is avoided.

[0112] In the embodiment of the application, the temporary SSID is temporary (the release time is uncertain, and the temporary SSID is closed immediately after the work is completed), non-public, and encrypted, so that the security of the temporary SSID is ensured. Even if the username and password information of the user account are known in advance, it is difficult to monitor. The security of the entire process is ensured, and is equivalent to the static password. Therefore, the encrypted password of the communication SSID can be transmitted in plaintext, the encryption and decryption process is reduced, and the complexity of the system is reduced.

[0113] In the embodiment of the application, the encrypted password of the communication SSID is sent to the legitimate user through a non-public temporary encrypted channel, the user is provided with convenience for accessing the encrypted WLAN network, the risk of the WLAN network being monitored is reduced, the encrypted public WLAN network is ensured, and the security is improved.

[0114] Figure 3 A flowchart of a network access method provided by the embodiment of the application is provided, the method is applied to a terminal in Figure 1 , and the method includes the following steps.

[0115] In step 301, a first connection request is sent to a target encrypted communication service set identifier (SSID) of a target AP, and the first connection request at least includes a connection password sent by the terminal for connecting the communication SSID.

[0116] In step 302, if it is determined that the access to the communication SSID fails, a second connection request is sent to the temporary SSID, with the username of the terminal as the SSID name of the temporary SSID and the user password of the terminal as the connection password of the temporary SSID.

[0117] In implementation, if the prompt information of connection failure feedback by the target AP is received, it can be determined that the access to the communication SSID fails, for example, the prompt information is "password error, please confirm and re-input".

[0118] In implementation, before the second connection request is sent to the target AP, with the username of the terminal as the SSID name of the temporary SSID and the user password of the terminal as the connection password of the temporary SSID, it can be determined that the connection password in the first connection request is the user password of the terminal, otherwise, a third connection request is sent to the communication SSID, with the user password of the terminal as the connection password, so that the AP obtains the user password, queries the username corresponding to the user password based on the user password, and creates a temporary SSID with the username as the SSID name of the temporary SSID and the user password as the encryption password of the temporary SSID.

[0119] In step 303, after it is determined that the temporary SSID is accessed, a request for obtaining the encryption password of the communication SSID is sent to the target AP.

[0120] In step 304, the encryption password of the communication SSID sent by the target AP is received, and the communication SSID is accessed based on the encryption password.

[0121] In implementation, the communication SSID and the encryption password of the communication SSID can also be stored, so as to automatically access the communication SSID based on the encryption password next time.

[0122] The network access method proposed in the application is described in detail below with specific embodiments.

[0123] Taking that the username and the user password of the terminal are stored in the server as an example, the server is configured with a user account information management module for managing user account information and storing the username and the user password, and is also configured with an information interaction module for information interaction with the AP. In fact, an automatic connection program can also be set in the server to realize the functions of the modules of the server.

[0124] Similarly, the AP side can also be configured with a WLAN driver module and an information interaction module, wherein the WLAN driver module is used to publish a communication SSID, obtain a MAC address associated with a terminal, and send a connection password for accessing the communication SSID; the information interaction module is used to interact with a server, query a user name according to a user password, and interact with a terminal to provide an encryption password of the communication SSID, and the AP can also be provided with an automatic connection program to realize the functions of the modules of the AP.

[0125] Similarly, the terminal side can also be configured with a WLAN driver module, an information interaction module, and a configuration storage module, wherein the WLAN driver module is used to attempt to connect to a communication SSID; if there is no encryption password of the communication SSID or the original encryption password of the communication SSID is invalid, the user password is used to replace the encryption password of the communication SSID, and the WLAN driver module is used to attempt to connect to the communication SSID again; the information interaction module is used to interact with an AP to obtain an encryption password of the communication SSID through a temporary SSID; the configuration storage module is used to record user account information (a user name and a user password) and an AP wireless channel password table (a MAC address and an SSID name of the communication SSID and an SSID encryption password). It should be noted that the terminal side stores the AP wireless channel password table, and can directly access a known AP, and only needs to interact with the network side when accessing a new AP or when the encryption password of the known AP is changed. The terminal can also be provided with an automatic connection program to realize the functions of the modules of the terminal.

[0126] The following takes a terminal configured with an automatic connection APP, an AP configured with an automatic connection AP, and a server configured with an automatic connection server as examples, and a terminal 1 first accesses a communication SSID of an AP 1 as an example. The specific network access process can be implemented according to the following steps.

[0127] Step 1: The AP 1 is online and publishes an encrypted communication SSID, and the name of the communication SSID is COMM-E.

[0128] Step 2: The terminal 1 installs the automatic connection APP, and inputs user account information (a user name and a user password) in the APP.

[0129] Step 3: When the terminal 1 enters the coverage range of the AP 1, the automatic connection APP attempts to connect to the COMM-E. Because it is the first connection, there is no encryption password of the COMM-E, and the automatic connection APP attempts to connect to the COMM-E again by using the user password as the encryption password of the COMM-E. Of course, the attempt cannot be connected successfully, but the AP 1 can obtain the MAC address of the terminal 1 and the user password.

[0130] Step 4: The auto-connection AP queries the auto-connection server for the username corresponding to the user password.

[0131] Step 5: The auto-connection server sends the corresponding username to the auto-connection AP after querying the user password.

[0132] Step 6: After obtaining the username, the auto-connection AP creates a non-public encrypted temporary SSID, and the temporary SSID uses the username as the SSID name and the user password as the encrypted password of the temporary SSID.

[0133] Step 7: After the auto-connection APP fails to connect COMM-E by replacing the COMM-E encryption password with the user account password, it continues to attempt to connect the (non-public) encrypted temporary SSID; until the AP1 creates the (non-public) encrypted temporary SSID, the connection is successful.

[0134] Step 8: After accessing the (non-public) encrypted temporary SSID, the auto-connection APP sends a request to the auto-connection AP to obtain the COMM-E encryption password.

[0135] Step 9: After receiving the request, the auto-connection AP confirms that the sender MAC address of the request is the terminal MAC address before, and sends the wireless channel encryption password in plaintext.

[0136] Step 10: After receiving the wireless channel encryption password, the auto-connection APP can successfully access the COMM-E of AP1, and add an entry of AP1 in the local AP wireless channel password table.

[0137] Step 11: After monitoring that the terminal 1 is associated with COMM-E, the auto-connection AP closes the (non-public) temporary SSID.

[0138] In specific implementation, the communication SSIDs published by the AP can also change the encryption password within a preset time or period to ensure the security of the network. The following takes the example of AP1 changing the password of COMM-E and terminal 1 accessing the communication SSID of AP1 again to implement the specific network access process according to the following steps.

[0139] Step 1: The auto-connection APP cannot access the COMM-E of AP1 with the original COMM-E encryption password. After the auto-connection AP monitors the connection failure, it also attempts to query the corresponding username from the auto-connection server with the password (original COMM-E encryption password). If the auto-connection server feedbacks a query failure, the auto-connection AP does not trigger the process of creating a (non-public) encrypted temporary SSID.

[0140] Step 2: After the auto-connection APP fails to access the COMM-E of AP1, the auto-connection APP replaces the COMM-E encryption password with the user password and attempts to connect to the COMM-E of AP1 again.

[0141] Step 3: After the auto-connection APP fails to access the COMM-E of AP1, the auto-connection APP replaces the COMM-E encryption password with the user password and attempts to connect to the COMM-E of AP1 again.

[0142] Step 4: After the auto-connection APP fails to access the COMM-E of AP1, the auto-connection APP replaces the COMM-E encryption password with the user password and attempts to connect to the COMM-E of AP1 again.

[0143] Step 5: After the auto-connection APP accesses the (non-public) encrypted temporary SSID, the auto-connection APP sends a request to the auto-connection AP to obtain the COMM-E encryption password.

[0144] Step 6: After the auto-connection APP accesses the (non-public) encrypted temporary SSID, the auto-connection APP sends a request to the auto-connection AP to obtain the COMM-E encryption password.

[0145] Step 7: After the auto-connection APP accesses the (non-public) encrypted temporary SSID, the auto-connection APP sends a request to the auto-connection AP to obtain the COMM-E encryption password.

[0146] In this way, the encryption password can be replaced at any time without the user's awareness, and different APs can be set with different communication SSID passwords, thereby improving the security of the entire system while ensuring convenience.

[0147] Based on the same technical concept, the embodiments of the present application also provide a network access device, and the network access device solves problems in a similar principle to the above network access method, so the implementation of the network access device can be referred to the implementation of the network access method, and the repeated parts will not be described again.

[0155] The feedback module 406 is configured to, after the obtaining module 402 determines that the connection password is not consistent with the current encryption password of the communication SSID, feed back prompt information of connection failure to the terminal, so that, after the terminal receives the prompt information, if it is determined that the currently sent connection password is not the user password of the terminal, the terminal sends a second connection request to the communication SSID with the user password as the connection password.

[0156] In some embodiments, after the different temporary SSIDs, each of which is non-public, has the connection password as an encryption password, and has a username as an SSID name, are created based on the obtained usernames and the connection password, the creating module 403 is further configured to:

[0157] monitor terminal access of each temporary SSID;

[0161] In response to a third connection request sent by the terminal to a temporary SSID, the third connection request including the terminal's username and the user password sent by the terminal;

[0162] If it is determined that the username of the third connection request matches the SSID name of any created temporary SSID, and the password of the third connection request matches the encryption password of the temporary SSID, then the terminal access target temporary SSID is determined.

[0163] In some embodiments, the first connection request may further include the Media Access Control (MAC) address of the terminal;

[0164] The sending module 405 is specifically used for:

[0165] If it is confirmed that the MAC address of the terminal requesting the encrypted password is the same as the MAC address of the terminal, then the password sending condition is met.

[0166] Based on the same technical concept, this application also provides a network access device. The principle of the network access device in solving the problem is similar to that of the network access method described above. Therefore, the implementation of the network access device can refer to the implementation of the network access method, and the repeated parts will not be described again.

[0170] The third sending module 503 is configured to send a request for obtaining an encrypted password of the communication SSID to the target AP after accessing the temporary SSID.

[0171] The receiving module 504 is configured to receive the encrypted password of the communication SSID sent by the target AP, and access the communication SSID based on the encrypted password.

[0172] In some embodiments, the second sending module 502 is specifically configured to:

[0173] If the prompt information of connection failure fed back by the target AP is received, it is determined that the access to the communication SSID fails.

[0174] In some embodiments, before the second sending module 502 sends a second connection request to the temporary SSID with the SSID name of the temporary SSID being the username of the terminal and the connection password of the temporary SSID being the user password of the terminal, the second sending module 502 is further configured to:

[0175] If the connection password in the first connection request is the user password of the terminal, the third sending module 503 sends a third connection request to the communication SSID with the user password of the terminal as the connection password; otherwise, the third sending module 503 sends a third connection request to the communication SSID with the user password of the terminal as the connection password.

[0176] In some embodiments, the receiving module 504 is further configured to:

[0177] After accessing the communication SSID based on the encrypted password, the receiving module 504 stores the communication SSID and the encrypted password of the communication SSID.
