Abstract: Methods, systems, and devices for wireless communications are described. A station (STA) may receive a wakeup radio (WUR) frame for the STA at a WUR. The STA may identify, from a number of packet number generation schemes, a scheme that the STA is to use to construct a packet number for the WUR frame. Following the scheme identification, the STA may generate a packet number for the received WUR frame using the identified scheme and determine whether to discard the WUR frame based on the generated packet number. In some implementations, the STA may determine whether the STA is to use, for communications received from an access point (AP) to the WUR, a same key or a second key, the second key being different from a first key used by the STA to receive protected communications from the AP to a primary radio of the STA.

Abstract: Systems, methods, and computer readable mediums for authenticating a device perform a method of receiving, at a second device, a first authentication protocol reauthentication response for the device, the authentication response including a reauthentication master session key (rMSK), transmitting, at the second device, a second first authentication protocol reauthentication response to a first access point based on the reauthentication master session key, generating, at the second device, a first pairwise master key (PMK) based on the reauthentication master session key, generating, at the second device, a key message to include the first pairwise master key, and transmitting, at the second device, the key message to the second access point.

Abstract: A method for wireless communication may include receiving a communication and determining an acknowledgement signature for an acknowledgment in response to the communication. The acknowledgment signature may allow for authentication with the transmitting wireless device. The acknowledgment signature may be based on a key shared with the wireless device. An acknowledgement frame (e.g., acknowledging reception of the communication) may then be sent to the transmitting wireless device. The content of the acknowledgement may be based on the acknowledgement signature. For example, the signature may be included in a frame control, duration, or address field. Determining the acknowledgement signature may include determining a unique signature based on information from the received communication (e.g., a cyclic redundancy check (CRC)), the shared key, and/or a hash function. In some cases, the acknowledgement frame may include an encryption header, and a message integrity check may be included as the acknowledgement signature.

Abstract: A method includes, prior to authenticating a mobile device, receiving by an access point a first message from the mobile device, determining that the mobile device is to be authenticated prior to responding to the first message, and sending to an authentication server a second message that includes an authentication request and the first message. The method also includes receiving from the authentication server a third message that includes a response to the authentication request and that further includes the first message.

Abstract: Apparatuses and methods are disclosed that may allow a wireless device to process an Ethertype data packet encapsulated in a frame based on whether the frame contains an Ethertype Packet Discrimination (EPD) indicator. The wireless device may receive the frame from another wireless device over a wireless network, and may detect a presence of the EPD indicator in the received frame. Then, the wireless device may identify a protocol type of the Ethertype data packet according to an EPD operation based on the presence of the EPD indicator, or may identify the protocol type of the Ethertype data packet according to an LPD operation based on an absence of the EPD indicator.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for secure transmission of packets with short headers. The methods may include temporarily suspending the use of packets that use a short MAC header (that lack a Key ID field) during re-keying procedures and resuming the use of such packets after a new default Key ID is established via the re-keying procedures.

Abstract: A particular method includes generating, at a mobile station, a probe request frame and a service discovery request. At least a first portion of the service discovery request may be encapsulated within the probe request frame to form a modified probe request frame. The modified probe request frame may be wirelessly transmitted, for example, to a particular access point or to all access points with range of the mobile station.
