Systems and methods for fast initial link setup security optimizations for PSK and SAE security modes

摘要

Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, an access point transmits a beacon to a station. The beacon comprises a Wi-Fi Protected Access II pre-sharked key (WPA2-PSK) authentication type. The access point further receives an authentication request from the station. The access point further transmits an authentication response to the station. The authentication response comprises the WPA2-PSK authentication type. The access point further retrieves a PSK and generates a PMK based on the PSK. The access point further receives an association request from the station after generation of the PMK. The association request comprises a key confirmation derived from the PSK. The access point further transmits an association response to the station in response to reception of the association request. The association response comprises the key confirmation.

主权项

1. A non-transitory computer-readable medium comprising code that, when executed, causes an apparatus to:
transmit a beacon to a station, the beacon comprising a Wi-Fi Protected Access II pre-shared key (WPA2-PSK) authentication type; receive an authentication request from the station, the authentication request comprising the WPA2-PSK authentication type and a first secure attribute exchange (SAE) information element; transmit an authentication response to the station, the authentication response comprising the WPA2-PSK authentication type and the first SAE information element; generate a pairwise master key (PMK) identifier based on the first SAE information element; receive an association request from the station after generation of the PMK identifier, the association request comprising a key confirmation derived from the PMK identifier and a second SAE information element; and transmit an association response to the station in response to receiving the association request, the association response comprising the key confirmation and the second SAE information element.
