Document Type and Number:
WIPO Patent Application WO/2022/144007
Kind Code:
A1
Abstract:
Disclosed in the present application are a control frame processing method, a station, a control frame generating method, an access point, and a computer readable storage medium. The control frame processing method comprises: receiving a control frame transmitted by an access point; parsing the received control frame and extracting a random value and an MIC value in the control frame; decrypting the random value and the MIC value by using a data key from the access point, so as to obtain an original plaintext of the random value and an original plaintext of the MIC value; calculating a local MIC value by using an MIC key from the access point, a non-check field in the control frame, and the random value; and determining whether the original plaintext of the MIC value is consistent with the local MIC value, and if yes, performing a corresponding control operation according to the control frame. The control frame processing method provided by the present application can effectively protect the control frame, prevent a hacker from using the control frame to perform wireless network attack, and ensure the security of a network.
