Detailed ways

The technical solutions of the present invention are further described below with reference to the accompanying drawings, but the present invention is not limited to the embodiments.

Embodiment 1

This embodiment provides a method for generating a password for a router and a router guest network, as shown in FIG. 1 and FIG. 2.

The router includes a guest network, and the guest network needs to log in using a login password, which is randomly generated by the router according to a user request.

The router includes a first network and a guest network, and the router accepts password generation request information sent by a user who has logged in to the first network to generate a random login password, and the random login password is used to log in to the guest network of the router.

In this embodiment, the router management application of the mobile terminal is used to operate. When the user needs to modify the password of the guest network, open the router management application on the mobile terminal, click to modify the password of the router guest network, and determine the encryption of the router guest network password. the way.

The router accepts the password generation request information sent by the user of the first network that has logged in to the router management application, that is, the password information of the router guest network and the encryption mode information of the router guest network password.

The router generates a random password login information and determines a random password login according to the password information of the modified router guest network sent by the user of the first network that has been logged in through the router management application and the encryption mode information of the router guest network password. The way information is encrypted. Further, after the random password login information is generated, it is sent to the user who has logged in to the first network.

After the router receives the password generation request information of the first network user that has logged in, the router randomly generates a password with a preset number of bits.

In this embodiment, the preset random number generated by the router is a combination of numbers and uppercase and lowercase letters; that is, when the router receives the modified password command sent by the router management application, the router random algorithm is from the number and the upper and lower case. A random password that randomly combines preset digits in the letters.

In this embodiment, the preset number of bits selected is 8 bits, that is, the number and the uppercase and lowercase English letters have 62 characters to form an array, and each time a random function is used to extract a number x in the range of 0 to 61, and map in the array. Is a[x]. Take eight times to form a random 8-digit password.

After generating the 8-digit random password, the random password is sent to the mobile terminal router management program.

In this embodiment, the router random algorithm is used to generate an 8-digit random password, including numbers and uppercase and lowercase English letters, which improves the security of the password, reduces the user's own thinking about designing the password, and simplifies the steps of modifying the password of the router guest network. Improve the user experience.

The router encrypts the generated random password login information according to an encryption method in the password encryption method information in the received password generation request information.

Currently, the encryption modes included in the wireless router are: WEP, WPA-PSK (TKIP), WPA2-PSK (AES).

WEP: Wired equivalent encryption, a security protocol for wireless local area networks (WLANs) defined in the 802.11b standard. WEP is used to provide the same level of security as a wired LAN. LAN is inherently more secure than WLAN, because the physical structure of the LAN protects it, and some or all of the network is buried inside the building to prevent unauthorized access. In many modern wireless access points and wireless routers, it is still supported by the encryption mode. Not only that, it is still one of the most encrypted methods used by individuals or companies.

WPA-PSK (TKIP): Based on the Wi-Fi Alliance 802.11i, a security mechanism called WPA is developed, which uses TKIP (Temporal Key Integrity Protocol), which uses the encryption algorithm or WEP. Encryption algorithm RC4, so there is no need to modify the hardware of the original wireless device.

WPA2-PSK (AES): After 802.11i, the Wi-Fi Alliance introduced WPA2, which supports AES (Advanced Encryption Algorithm), so it requires new hardware support, using CCMP (Counter Mode Cipher Block Chain Message Complete Code Protocol). In WPA/WPA2, the generation of PTK depends on PMK, and PMK is obtained in two ways. One is that the form of PSK is pre-shared key, in this way PMK=PSK, and in another way, authentication is required. The server and the site negotiate to generate the PMK.

In the three encryption methods described above, the password encryption mode of the guest network of the router is determined.

After the router generates the random password login information according to the password generation request information of the first network user that has logged in and determines the encryption mode, the generated random password is sent to the router application management program.

After receiving the random password of the generated guest network of the router, the router management application of the mobile terminal is displayed on the page of the router management application, and the user can enter the guest network according to the random password to perform Internet access.

In this embodiment, the router management application provides two display modes for the generated guest network random password: plain text display and two-dimensional code display. Users are free to choose.

Plain text display: When the user selects the plain text display button, the generated random password is directly displayed on the router management application page, directly telling the password information to other people who need to connect to the guest network;

QR code display: When the user selects the QR code display, the generated random password is converted into a QR code and displayed on the router management application page for others to scan, so that the password information is transmitted to other people who need to connect to the guest network. .

The specific steps are as follows:

Receiving a random password generated by the router;

The user determines whether to perform a two-dimensional code display of the guest network password;

If the two-dimensional code display of the guest network password is performed, the router management application generates a corresponding two-dimensional code of the random password, and displays the page of the router management application;

If the QR code of the guest network password is not displayed, the router management application directly displays the random password on the page.

In this embodiment, by accepting the password generation request information sent by the user of the first network that has logged in, a random password is generated for the guest network of the router, and an encryption method for determining the random password is provided, and two password display manners are provided to implement one-key modification of the router. The purpose of the guest network password. Receiving the random password generated by the router, displaying the random password on the router management application page of the mobile terminal, improving the security of the password, reducing the user's own thinking about designing the password, simplifying the steps of modifying the password of the router guest network, and improving the user Experience.

In the second embodiment, after receiving the password generation request information and the random login password encryption mode information, the embodiment generates a random login password by generating a random password module, and determines an encryption mode of the random login password.

When the first network user that has logged in does not select the encryption mode of the random password of the router guest network, the default encryption mode is determined as the encryption mode of the router guest network password; the default encryption mode in this embodiment is the system default encryption mode. That is WEP encryption.

The above module can select the encryption method according to the user's preference, or the user can omit the selection step and directly use the default encryption method, thereby improving the encryption mode selectivity and experience.

After receiving the random password login information, the user who has logged in to the first network may select a different display mode including a digital display or a two-dimensional code generated by a random number for the visitor to select to receive the random login password.

The random password display mode selected by the user who has logged in to the first network can automatically generate a two-dimensional code corresponding to the random password, so that the user can convert the generated random password into a two-dimensional code and display it on the page for others to scan. Therefore, it is more convenient and convenient to transmit the password information to other people who need to connect to the guest network.

Further, the embodiment includes: a wireless network module that receives the password generation request information through the wireless network and transmits the generated random password login information through the wireless network.
