    Abstract: This disclosure describes systems, methods, and devices related to using encrypted 802.11 association. A device may identify a beacon received from an access point (AP), the beacon including an indication of an authentication and key manager (AKM); transmit, to the AP, an 802.11 authentication request including an indication of parameters associated with the AKM; identify an 802.11 authentication response received from the AP based on the 802.11 authentication request, the 802.11 authentication response including a message integrity check (MIC) using a key confirmation key (KCK) and an indication that the parameters have been selected by the AP; transmit, to the AP, an 802.11 association request encrypted by a security key based on an authenticator address of the AP; and identify an 802.11 association response received from the AP based on the 802.11 association request, the 802.11 association response encrypted by the security key.

    Abstract: This disclosure describes systems, methods, and devices related to secure MAC header. A device may generate a frame comprising a secure medium access control (MAC) header. The device may cause to send the frame to one or more STAs. In particular, the device may include processing circuitry coupled to storage, where the processing circuitry is configured to generate a frame comprising a MAC header that includes one or more unencrypted fields and one or more encrypted fields. The frame may be one of a management frame or a data frame and the one or more unencrypted fields may include an address 3 (A3) field. The processing circuitry may also be configured to instruct to send the frame to one or more stations (STAs).

    Abstract: The disclosure provides a method for resisting downgrade attack for private limited connection, comprising: performing a 4-way handshake between an initiating entity and a responding entity to establish a PMKSA; receiving, by the initiating entity, a frame from the responding entity during the 4-way handshake, wherein the frame comprises an indication of usage of private limited connection for all responding entities in a network identified by a SSID of the responding entity; and establishing, by the initiating entity, a private limited connection in the network identified by the SSID of the responding entity.
