Description

A way to connect to secure Wi-Fi without entering a password

technical field

The invention relates to the technical field of wireless access point connection, in particular to a method for connecting to secure Wi-Fi without inputting a password.

Background technique

Wireless network is a wireless network technology defined by IEEE. When IEEE officially defined the 802.11 standard in 1999, IEEE selected and recognized the wireless network technology invented by CSIRO as the best wireless network technology in the world. Therefore, CSIRO's wireless network technology standard, It became the core technical standard of wireless fidelity in 2010. Wireless Internet access can be simply understood as wireless Internet access. Almost all smart phones, tablet computers and notebook computers support wireless fidelity Internet access. It is the most widely used wireless network transmission technology today.

Wi-Fi is a brand of wireless network communication technology, held by the Wi-Fi Alliance. The purpose is to improve the interoperability between wireless network products based on the IEEE 802.11 standard. In fact, it is to convert the wired network signal into a wireless signal, and then use a wireless router to receive it for related computers, mobile phones, tablets and other devices with Wi-Fi technology.

With the rapid development of the mobile Internet, people's demand for using mobile devices to surf the Internet has also greatly increased, so the dependence on Wi-Fi is also increasing. The setting of Wi-Fi requires at least one wireless access point (Access Point, AP) and one or more wireless clients (client), and the wireless client sends a connection request to the wireless access point. Under the existing technology, there are generally three ways of Wi-Fi authentication and connection: 1. Open; 2. WPA/WPA2-PSK; 3. 802.1x. For an open wireless network, no password is required, any user can connect, and all data packets are broadcast in plain text. Therefore, the use of open Wi-Fi also brings many security problems, such as: personal information leakage, account password theft, etc. For WPA/WPA2-PSK Wi-Fi, it is our commonly used secure Wi-Fi connection and authentication technology. It needs to enter the correct password to connect, and its security can be well guaranteed; but the wireless client must know the security in advance. Wi-Fi password, and when the wireless access point modifies the secure Wi-Fi password, the wireless client must re-enter the correct password to connect to the secure Wi-Fi, and the access steps are cumbersome. For Wi-Fi using 802.1x technology, the Radius server needs to be enabled to authenticate wireless clients. It is usually used at the enterprise level and has the highest security, but it is expensive and has certain limitations.

Today, wireless clients need to know a password or perform third-party authentication when connecting to secure Wi-Fi to connect and access the Internet. For Wi-Fi using WPA/WPA2-PSK authentication encryption technology, only one connection password can be configured, and the password length must meet 8 to 64 characters. When the connection password is changed, all wireless clients must change the connection password To connect to Wi-Fi, this is a cumbersome thing for wireless clients.

Wi-Fi using 802.1x authentication and encryption technology has multiple user names and passwords. The wireless client needs to enter the correct user name and password to successfully connect. For enterprise or school users, the user name and password are usually the same as those in the AD domain. Username and password remain the same. Since the storage and management of user names and passwords itself requires additional technology to ensure security, after the user changes the password, the Wi-Fi connection password must also be manually modified. If there is no modification, not only will you not be able to connect to the secure Wi-Fi provided by the company, but your user name and password may be locked and you may not be able to log in.

In particular, public Wi-Fi has been widely used. When connecting to a secure public Wi-Fi, the provider usually needs to inform the Wi-Fi password used, which makes management and auditing of public Wi-Fi difficult. Therefore, the existing open Wi-Fi does not require a password to connect, but needs to receive a SMS verification code or use other means or methods such as APP or login account to access the Internet. When connecting to open Wi-Fi, its security cannot be guaranteed. When using open Wi-Fi, because there is no password protection, there may be sniffers who may take away our online account, password and other information; there may also be ARP attacks (man-in-the-middle attacks), resulting in the privacy of files, photos, etc. Data is stolen; there may also be malicious DNS, forcing Internet users to connect to phishing websites, and online banking is stolen. A sample security survey shows that 21% of the 80,000 public Wi-Fi in the country are at risk.

Contents of the invention

The purpose of the present invention is to provide a method for connecting to a secure Wi-Fi without entering a password in order to overcome the above-mentioned defects in the prior art.

detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Working principle of the present invention is:

The present invention provides a method for connecting to secure Wi-Fi without inputting a password, the method comprising:

The wireless access point provides secure Wi-Fi with multi-password features. Secure Wi-Fi has the following features:

1. Wi-Fi uses a password to protect the connection;

2. Can use at least two passwords to connect to Wi-Fi;

3. The wireless client does not need to know the specific password of the secure Wi-Fi;

4. The information used for communication between the wireless access point and the wireless client using Wi-Fi has been encrypted.

Its specific characteristics are:

1. The secure Wi-Fi itself is protected by a password, and you can connect by entering the correct specific password;

2. If the wireless client does not know the specific password set by the secure Wi-Fi access point, the password for connecting to the secure Wi-Fi is provided by the wireless client, and the wireless access point decides based on the unique information provided by the wireless client Allow or deny connection requests from wireless clients;

3. If the wireless client has successfully connected to the secure Wi-Fi, if there is no change in the configuration of the secure Wi-Fi, it can continue to use the original request configuration information to connect to the secure Wi-Fi. Once the secure Wi-Fi -Fi has a configuration change, and the wireless client needs to make a connection request again according to the situation of not knowing the secure Wi-Fi password.

Multi-password Wi-Fi means that multiple passwords can be used to connect to secure Wi-Fi, of which only one specific password is used to manage and configure secure Wi-Fi, and all other passwords can only be connected to secure Wi-Fi. Fi. A specific password is provided by the wireless access point to protect its own secure Wi-Fi as well as to manage and configure that secure Wi-Fi. Other connection passwords are provided by the wireless client requesting to connect to the secure Wi-Fi, and the validity of the connection passwords is determined by the wireless access point according to management rules.

The multi-password feature of Wi-Fi means that the secure Wi-Fi provided by the wireless access point supports the use of multiple passwords to connect, and different wireless clients use their own unique information as the connection password to connect to the secure Wi-Fi. The wireless client does not need to enter the password to connect to the secure Wi-Fi. The password provided by the wireless client needs to be recognized by the wireless access point, so as to achieve the connection of the secure Wi-Fi without entering the password.

According to the multi-password feature secure Wi-Fi provided by the above wireless access point, the wireless client requests to connect, including:

The wireless client first turns on the Wi-Fi function, which can scan the surrounding safe Wi-Fi with such multi-password features, and request to connect.

When a wireless client requests to connect to a certain secure Wi-Fi, the wireless access point detects whether the wireless client has successfully connected to the secure Wi-Fi before and whether the configuration of the secure Wi-Fi provided by the wireless access point has been changed. If the wireless client has been successfully connected to the secure Wi-Fi and the configuration of the secure Wi-Fi has not been changed, the connection request of the wireless client is directly allowed; otherwise, the wireless client is asked for credentials to connect to the secure Wi-Fi.

The wireless client receives the access request information from the wireless hotspot, and the wireless client provides a password to request to connect to the secure Wi-Fi. Preferably, the connection password provided by the wireless client is in character form of the MAC address of the wireless network card (for example, if the MAC address is: AB:12:CD:34:EF:56, then the provided password is: AB12CD34EF56). In the case that the above connection password provided by the wireless client is invalid, the connection password provided by the wireless client is changed to the serial number (for example: if the serial number is: 861364035241546, then the provided password is changed to: 861364035241546)

The wireless client replies to the access request query information sent by the wireless access point, and the wireless access point receives the connection password provided by the wireless client, and decides whether to allow the connection request of a specific wireless client according to the rules.

The password provided by the wireless access point through the wireless client includes: 1 specific password provided by the secure Wi-Fi access point, 2 the character form of the MAC address of the wireless network card, and 3 the hardware serial number of the wireless client.

The wireless hot access point will process the access requests sequentially according to the time sequence of the access requests of the wireless clients. There are two processing results: 1. Allow the wireless client to connect to the secure Wi-Fi; 2. Refuse the wireless client to connect to the secure Wi-Fi.

The wireless access point needs to identify the password provided by the wireless client to make the connection request, so as to decide whether to allow the connection request of the wireless client. For example: 1. If the password provided by the wireless client is: 024521@9083, and the password itself is not the connection password of the secure Wi-Fi itself, nor is it the MAC address of the wireless network card used by the wireless client, the wireless access point therefore rejects the password. The connection request of the wireless client; 2. If the MAC address of the wireless network card used by the wireless client is: 02-24-2C-5B-15-0C, the wireless client will provide a request for a secure Wi-Fi connection without entering a password. The password is: 02242C5B150C, so the wireless access point allows the connection request of the wireless client, so as to realize the connection to secure Wi-Fi without entering the password.

The wireless access point authenticates the wireless client to connect to the secure Wi-Fi without entering a password. The characteristics are: 1. When the wireless client connects to the secure Wi-Fi, there is no password; The MAC address or serial number of the network card is used as the password to connect to the secure Wi-Fi; 3. When the wireless client connects to the secure Wi-Fi, it enters the connection password of the secure Wi-Fi itself, the MAC address or serial number of its own wireless network card. Other passwords.

When the wireless client connects to secure Wi-Fi, it provides its own unique information (wireless network card MAC address or serial number) as the connection password, and the wireless access point detects the validity of the connection password provided by the wireless client. , so as to solve the problem that the secure Wi-Fi password must be known to connect to secure Wi-Fi, the password needs to be manually entered for the first connection, and the wireless client needs to re-enter the correct password after the wireless access point modifies the secure Wi-Fi connection password. The cumbersome issues in the process of securing Wi-Fi,

Example:

The core idea of the present invention is: the wireless access point establishes a secure Wi-Fi with multi-password characteristics; the wireless client scans that the secure Wi-Fi exists around, and the wireless client requests to connect with a default password; the wireless access point Determine the provided default password to allow the wireless client's connection request. Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

Step 1 As shown in Figure 2, the wireless access point provides secure Wi-Fi, and the SSID of the secure Wi-Fi is Hello. This secure Wi-Fi can use multiple passwords to connect.

Step 2: The wireless client enables the Wi-Fi function and scans the surrounding Wi-Fi. If a secure Wi-Fi supports multi-password connections, the wireless client (for example, an Android phone) will display "You can use the default password to connect" to prompt the user that the secure Wi-Fi supports connections without entering a password.

Step 3 The wireless client requests to connect to the secure Wi-Fi, and you can click to use the default password to connect.

Step 4: The wireless access point indicates to the wireless client that it needs to provide credentials for connecting to the secure Wi-Fi.

Step 5 The wireless clients (A, B) have successfully connected to the secure Wi-Fi with the provided default passwords, and the secure Wi-Fi has not changed. The wireless access point directly allows the connection requests of A and B (green in Figure 2 dashed lines 1 and 2).

Step 6: When the wireless client (C, D, E) connects to the secure Wi-Fi for the first time, it uses its own unique information (wireless network card MAC address or serial number) as the connection password to make a connection request.

Step 7: The wireless access point processes and judges the validity of the connection password provided by the wireless client according to the sequence (C, D, E) of the password provided by the wireless client.

Step 8. The password provided by the wireless client C is valid, and the wireless access point allows the wireless client to connect to the secure Wi-Fi (shown by dotted line 3 in FIG. 2 ).

Step 9 The password provided by the wireless client D is valid, and the wireless access point allows the wireless client to connect to the secure Wi-Fi (shown by the dotted line 4 in FIG. 2 ).

In step 10, the password provided by the wireless client E is valid, and the wireless access point allows the wireless client to connect to the secure Wi-Fi (shown by dotted line 5 in FIG. 2 ).

Step 11 The wireless client successfully connects to the secure Wi-Fi without entering a password.
