Method and device for wireless access authentication

Abstract

The embodiment of the invention provides a method and device for wireless access authentication, which relate to the field of wireless communication and can be used for preventing a secret key from being broken. The method comprises the following steps: the frequency of consecutive failures in access of first user equipment to gateway device is counted and recorded after that feature characters of the first user equipment are not prestored in the gateway device and the first user equipment fails to use a secret key for the first time to try to access the gateway device are judged; if the frequency is larger than a pre-arranged first threshold value, a new secret key can be generated, and WiFi access authentication is performed on user equipment of the gateway device of which the feature characters are prestored through the new secret key; and the embodiment of the invention is used for wireless access authentication.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for wireless access authentication. Background technique [0002] With the development of wireless communication, wireless fidelity (WIFI for short) technology is becoming more and more common, and the security of WIFI access point access key has also become a research topic for technicians. The initial keys are factory-set or the manufacturer provides a completely random serial number for the default key of the WIFI access point, and the general user will not modify these factory settings, and these keys are immutable, users always With this key, as long as the hacker discovers the rules or attacks the WIFI access point by traversal, it will have a great impact on the security of the WIFI device. In this way, the normal use of the WIFI device by the user cannot be guaranteed, and If the hacker is connected to the WIFI device, the interests of th...
