It should be understood that the number of terminal devices and terminal devices to be accessed in fig. 1 is merely illustrative. There may be any number of terminal devices and terminal devices to be accessed, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for sharing a wireless network in accordance with the present application is shown. The method for sharing the wireless network of the embodiment comprises the following steps:
step 201, obtaining the name and access verification information of the wireless network to be shared.
In this embodiment, an electronic device (for example, the terminal device shown in fig. 1) on which the method for sharing a wireless network operates may acquire the name and the access authentication information of the wireless network to be shared in various manners, for example, from a file pre-stored in the terminal device, or from another device through a wired or wireless connection manner. The name of the wireless network to be shared, that is, the SSID (Service Set Identifier) of the wireless network, is used to identify the wireless network to be shared, and may be a wireless network defined by a user or may be automatically generated when the wireless network is configured. The access authentication information is used for authenticating when accessing the wireless network to be shared, and may be a character string composed of numbers or letters or symbols or other implementable forms.
In some optional implementation manners of this embodiment, after acquiring the name and the access verification information of the wireless network to be shared, the terminal device may attempt to access the wireless network to be shared, so as to verify whether the access verification information is correct.
Step 202, encrypting the access verification information to obtain a ciphertext character string.
In this embodiment, various encryption algorithms may be used to encrypt the access authentication information, such as a symmetric encryption algorithm, an asymmetric encryption algorithm, and the like. After the access verification information is encrypted, a corresponding ciphertext character string can be obtained.
In some optional implementations of the present embodiment, the step 202 may be implemented by the following sub-steps not shown in fig. 2: calling a key generation function to generate a key by adopting a preset encryption type; and calling an encryption function to encrypt the access verification information by using the generated key to obtain a ciphertext character string.
In this implementation manner, a symmetric encryption algorithm may be used to encrypt the access authentication information, and in the encryption process, a key generation function is first called to generate a key, and then an encryption function is called to encrypt the key by using the generated key, so as to obtain a ciphertext character string.
And step 203, obtaining an access code of the wireless network to be shared based on the name and the ciphertext character string.
In this embodiment, the name and the ciphertext character string of the wireless network to be shared may be combined or added to obtain the access code of the wireless network to be shared. The access code may be a data frame with a fixed format, for example, the access code may have a fixed length, the parts constituting the access code have a fixed arrangement order, and the like.
In some optional implementations of this embodiment, the step 203 may be implemented by the following sub-steps not shown in fig. 2: and arranging the secret key, the name and the ciphertext character string in a preset arrangement sequence to obtain the access code.
In this implementation, the order of arrangement of the parts in the access code may be set in advance, for example, the parts are arranged in a manner that the name is first, the key is second, and the ciphertext character string is third. In this way, after the access terminal acquires the access code, the access terminal can read the access code in sequence, so as to determine each part in the access code.
In some optional implementation manners of this embodiment, when determining the access code, the data length of each portion or the data composition length of each portion may be determined after obtaining the key, the name, and the ciphertext character string. After the data length of each part is determined, the length values can be added into the access code together, so that the terminal equipment to be accessed can quickly determine the size and the position of the key, the name and the ciphertext character string after receiving the access code. When the data composition length of each part is preset, the terminal equipment to be accessed sequentially reads after receiving the access code, and determines the data of each part by combining the preset arrangement sequence.
In some optional implementations of this embodiment, the step 203 may also be implemented by the following sub-steps not shown in fig. 2:
adding a preset key identifier in front of the key to obtain the identifier-added key; adding a preset ciphertext character string identifier in front of the ciphertext character string to obtain the ciphertext character string added with the identifier; adding a preset name identifier before the name of the wireless network to be shared to obtain the name of the added identifier; combining the key with the added identifier, the ciphertext character string with the added identifier and the name of the added identifier to obtain an access code main body; and adding a preset check mark in front of the access code main body, and adding a preset finishing mark behind the access code main body to obtain the access code.
In this implementation manner, a preset key identifier, a preset ciphertext character string identifier and a preset name identifier may be added before the key, the ciphertext character string and the name of the wireless network to be shared, and then the key and the key identifier are bound, the ciphertext character string and the ciphertext character string identifier are bound, the name and the name identifier are bound, the bound three parts are combined, and the combined data is used as an access code main body; a preset check identifier can be added in front of the access code main body, so that after the access code is acquired by the terminal to be accessed, the received data is determined to be the access code of the wireless network to be shared according to the check identifier; the preset end mark can be added behind the access code main body, so that the terminal to be accessed determines whether the access code is complete or not according to the end mark after determining that the received data is the access code, and the phenomenon that the data transmission is interrupted due to disconnection of a data transmission link or other reasons, so that the incomplete access code is received, and the wireless network to be shared cannot be accessed is avoided.
Exemplarily, the Encryption type may be AES (Advanced Encryption Standard), and the key generation function is invoked to generate the symmetric key K; setting the check mark as M by hard coding, setting the SSID of the wireless network to be shared as S, and setting the ending mark as E; calling an encryption function, encrypting the password N of the wireless network to be shared by using the key K, and generating a ciphertext character string N1; the file of the access code consists of M + K + S + N1+ E.
And step 204, sending the access code to the terminal to be accessed so as to share the wireless network to be shared with the terminal to be accessed.
In this embodiment, the terminal device executing the method for sharing the wireless network may send the obtained access code to the terminal to be accessed through various communication modes, so as to share the wireless network with the terminal to be accessed.
In some optional implementation manners of this embodiment, the terminal may send the access code to the terminal to be accessed through near field communication or an infrared or bluetooth manner.
When the terminal equipment and the terminal equipment to be accessed have the near field communication function, the terminal equipment and the terminal equipment to be accessed can transmit the access code through near field communication. It will be appreciated that the access code may also be transmitted by other means of data transmission, such as infrared, bluetooth, radio frequency identification technology or other implementable means.
By the data transmission mode, the security and the rapidity of the wireless network login information in the transmission process can be effectively protected, and the monitoring and tampering in the data transmission process are avoided; and because the user does not need to manually search the wireless signal and input the password, the time for accessing the wireless network is shortened, and meanwhile, the user can set the wireless network to be hidden, so that the possibility that the wireless network is searched by a malicious attacker is reduced.
In some optional implementations of this embodiment, the method further includes the following steps not shown in fig. 2: and displaying the transmission state of the transmission access code.
In this implementation, the sending state includes: successful transmission, failed transmission, or in transmission. When the terminal equipment sends the access code to the terminal equipment to be accessed, the sending state can be displayed on a display screen of the terminal equipment in the sending process of the access code.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for sharing a wireless network according to the present embodiment. In the application scenario of fig. 3, the user selects to turn on an NFC (near field communication) function through the smartphone 31, and selects one wireless network as the wireless network to be shared. Each wireless network includes a name and an access password (only the name of the wireless network is displayed on the screen of the smartphone 31). After selecting a wireless network to be shared, the smartphone 31 automatically generates an access code of the selected wireless network. Then, the smartphone 31 is in near field communication with the smartphone 32 that wants to access the wireless network, wherein the smartphone 32 also turns on the NFC function and sends the access code to the smartphone 32. After the transmission is completed, the smartphone 31 displays a transmission success interface.
The application scenario shown in fig. 3 may be applied to sharing of a home wireless network, and when a visitor visits, the visitor may use a smart phone or a tablet computer or other electronic devices to perform data transmission with an electronic device of a host, so that the visitor may quickly access the home wireless network.
Of course, the method for sharing the wireless network of the embodiment can also be applied to smart homes, home medical care and public places. For example, a user can interact with each device in an intelligent home through the portable terminal device, so that each device can be quickly accessed to a small internet of things formed by a home wireless network; in public places (hotels, restaurants and large conference centers), names and passwords of wireless networks can be encrypted and set into electronic chips, two-dimensional codes or other devices, and users can intervene in the wireless networks by scanning or contacting the wireless networks through intelligent equipment.
The method for sharing the wireless network provided by the embodiment of the application encrypts the access verification information of the wireless network to be shared, generates the access code of the wireless network to be shared by combining the name of the wireless network to be shared, and then shares the access code to the terminal to be accessed. The method avoids the complex steps that the user needs to input the verification information when the terminal is accessed into the wireless network, and realizes the rapid and convenient access to the wireless network.
Fig. 4 shows a flowchart 400 of yet another embodiment of a method for accessing a wireless network according to the present application. The method for accessing the wireless network of the embodiment comprises the following steps:
In this embodiment, an electronic device (for example, the to-be-accessed terminal device in fig. 1) executing the method for accessing the wireless network may acquire an access code of the to-be-accessed wireless network in various manners, for example, acquire the access code from a terminal sharing the to-be-accessed wireless network in a near field communication manner. The access code is obtained based on the name of the wireless network to be accessed and a ciphertext character string obtained by encrypting the access verification information of the wireless network to be accessed.
After the access terminal device obtains the access code, the access code is firstly analyzed to obtain the name and the ciphertext character string corresponding to the access verification information.
In some optional implementations of this embodiment, the access code further includes a key used for encrypting the access authentication information. The step 402 may specifically implement the parsing of the access code by the following steps not shown in fig. 4: and sequentially reading the access codes, and determining the name, the ciphertext character string and the secret key based on a preset arrangement sequence.
In this implementation manner, each part in the access code may be arranged according to a preset arrangement order, and after receiving the access code, the access terminal reads data in the access code in sequence, and in combination with the preset arrangement order, may determine a name, a ciphertext character string, and a key of the wireless network to be accessed.
In some optional implementation manners of this embodiment, when parsing the access code in step 402, it may also be first detected whether the access code includes a check identifier and an end identifier. The check mark is used for representing the file attribute, after receiving the data, the terminal equipment to be accessed detects whether the check mark is included, and when the check mark exists, the received data is determined to be the access code of the wireless network to be accessed. The end identifier is used to indicate whether the access code is complete, and when the access code exists, the end identifier indicates that the access code received by the terminal to be accessed is complete.
And after the received access code is determined to comprise the two identifications, further detecting whether the access code comprises a secret key identification, a ciphertext character string identification and a name identification. The key identification is bound with the key, the ciphertext character string identification is bound with the ciphertext character string, and the name identification is bound with the name of the wireless network to be accessed. When the terminal equipment to be accessed reads the access code, which part of the access code belongs to the secret key, the ciphertext character string and the name can be quickly determined by reading the secret key identifier, the ciphertext character string identifier and the name identifier.
When the three identifiers exist, extracting the character string indicated by the key identifier as the key, extracting the character string indicated by the ciphertext character string identifier as the ciphertext character string, and extracting the character string indicated by the name identifier as the name of the wireless network to be accessed.
And step 403, decrypting the ciphertext character string to obtain access verification information.
After the access terminal obtains the name of the wireless network to be accessed, the key used for encryption and the ciphertext character string corresponding to the access verification information through analysis, the ciphertext character string is decrypted, and then the access verification information of the plaintext can be obtained.
In some optional implementation manners of this embodiment, when decrypting the ciphertext character string, a preset decryption type is used, and a decryption function is called to decrypt the ciphertext character string by using a key, so as to obtain the access verification information.
It will be appreciated that the type of decryption described above should correspond to the type of encryption employed in the encryption. For example, the AES encryption type is used for encryption, and the AES decryption type is also used for decryption.
And step 404, accessing the wireless network to be accessed based on the name and the access authentication information.
And according to the obtained name and access verification information of the wireless network to be accessed, the terminal to be accessed can be quickly accessed into the wireless network to be accessed.
In some optional implementation manners of this embodiment, before the terminal device accesses the wireless network, a state of a switch accessing the wireless network may be detected first, and when it is detected that the state of the switch accessing the wireless network is off, the switch accessing the wireless network is automatically turned on. And when the state of the switch for accessing the wireless network is detected to be open, detecting whether the wireless network is accessed currently. And when detecting that the wireless network is accessed currently, displaying a wireless network switching inquiry message on the terminal to be accessed. After the user confirms the wireless network switching, the terminal to be accessed disconnects the accessed wireless network, and automatically accesses the wireless network to be accessed.
This is particularly useful for enabling fast handover of an accessed wireless network when the wireless network is currently accessed and a terminal to be accessed is performing network data exchange or when the accessed wireless network is a paid network or an unsecured network.
In some optional implementation manners of this embodiment, the terminal device may further display an access status of accessing the wireless network to be accessed, such as access success, access failure, or access in progress.
According to the method for accessing the wireless network provided by the embodiment of the application, after the terminal to be accessed acquires the access code of the wireless network to be accessed, the access code is analyzed to obtain the encrypted access verification information and name, the access verification information is obtained by decryption, and finally the wireless network to be accessed is accessed based on the name and the access verification information of the wireless network to be accessed, so that the tedious step that a user needs to input the verification information when the terminal is accessed into the wireless network is avoided, and the wireless network can be accessed quickly and conveniently.
