Description

Wireless network access device and matching method thereof

The present invention relates to network access, and in particular, to a network access device and a method for pairing the same with a wireless communication device.

With the rapid development of wireless technologies and products, users of wireless communication devices are increasingly demanding the security performance of wireless network access devices. For example, the commonly used dual-mode mobile phone supporting Wireless Fidelity (Wi-Fi) communication is mainly paired with a wireless network access device by using Hypertext Transfer Protocol Secure (HTTPS). During use, the dual-mode mobile phone user simply presses the pairing button on the mobile phone to make a pairing request to the wireless network access device through the HTTPS mechanism. The wireless network access device verifies its identity upon receipt of the pairing request and provides a shared key for encryption, ie, the pairing is completed. After that, the wireless network access device and the dual-mode mobile phone can establish an encrypted wireless connection to transmit voice data. This pairing mode allows users to enjoy the security of wireless Internet phone voice in a very simple situation.

However, before using the HTTPS phase, the wireless network access device needs to turn off the wireless security mechanism in use for pairing. In this case, if the illegal pirate presses the pairing button before the legitimate user, the legitimate user will be caused. The connection was denied without knowing, and the satisfaction with the wireless network access device was greatly reduced. At the same time, illegal pirates can not only use the call connection service, but also all passwords such as passwords encrypted by the wireless network. Further, illegal users can also secretly steal legitimate users. After the encrypted wireless packet sent and decrypted, it seriously jeopardizes communication security.

In view of this, it is necessary to provide a wireless network access device, which can effectively prevent a security hole when an illegal pirate first presses a pairing button when a pair is paired with a wireless communication device, thereby improving security performance.

In addition, it is also necessary to provide a method for pairing a wireless network access device with a wireless communication device, which can effectively prevent an illegal pirate from pressing a pairing button when a wireless network access device is paired with a wireless communication device. Security vulnerabilities to improve security.

At this time, after the user of the wireless communication device 20 sees the state presented by the signal light, the pairing code in the corresponding pairing request is determined by comparing the light code comparison table 1010. For example, if the user sees that the first signal lamp 1000 and the fourth signal lamp 1006 are constantly on, and the second signal lamp 1002 and the third signal lamp 1004 are not lit, the light code comparison table on the outer casing of the wireless network access device 10 is used. 1010 to determine that the pairing code in the pairing request is "a". In the present embodiment, since the wireless communication device 20 is connected to the wireless network access device 10 by the HTTPS mechanism, when the wireless communication device 20 needs to be paired with the wireless network access device 10, a pairing request is sent to the wireless device. Network access device 10. In this embodiment, the pairing request may be "https://IP_Address/pair/pairing code" ", where IP_Address is the IP address of the wireless network access device 10.

In step S304, the matching module 106 receives the pairing request from the wireless communication device 20, and acquires the pairing code therein.

In step S306, the matching module 106 determines whether the pairing code in the pairing request matches the pairing code corresponding to the state selected by the lighting module 104 in the light code comparison table 1010.

If the pairing code in the pairing request matches the pairing code corresponding to the selected state in the light code comparison table 1010, the wireless communication device 20 is a legitimate user, and the pairing module 108 is implemented with the wireless communication device 20 in step S308. pair. In this embodiment, the pairing module 108 feeds back the XML file to the wireless communication device 20 to implement pairing, wherein the XML file includes encryption parameters such as WEP, WPA, WPA2, and the like.

In step S309, the lighting module 104 drives the signal light 100 to display the pairing success.

If the pairing code in the pairing request does not match the pairing code corresponding to the selected state in the light code comparison table 1010, the wireless communication device 20 is an illegal user, and the pairing module 108 rejects the wireless communication device 20 in step S310. Pairing.

In step S311, the lighting module 104 drives the 100 signal light to indicate that the pairing is unsuccessful. In this embodiment, the signal light 100 indicates whether the pairing is successful by its state, and the state of whether the pairing is successful can be preset. For example, all the signal lights can be set to be bright to display the pairing success, and all the signal lights are set to blink. To show that the pairing was not successful. In other embodiments, There are other ways to show if the pairing was successful. At this point, legitimate users can successfully connect through the wireless network access device 10, while illegal users cannot, thus effectively protecting the rights and privacy of legitimate users.
