    Abstract: Techniques are directed toward secure scrambling. An example method includes receiving, by a first communication device a physical layer protocol data unit (PPDU) frame from a second communication device. The first communication device can determine a PPDU frame type based at least in part on a preamble of the PPDU frame. The first communication device can apply a PPDU frame type-based key and a determined service field value to implement a descrambling process for a medium access control (MAC) header of the PPDU frame. The first communication device can descramble a payload based at least in part on de-obfuscating the MAC header. The first communication device selecting a scrambler seed for scrambling an acknowledgement (ACK) message. The first communication device scrambling the ACK message based on the selected scrambler seed.

    Abstract: Techniques are directed toward secure scrambling. An example method includes a first device encrypting a payload to be included in a physical layer protocol data unit (PPDU) frame. The determining a PPDU frame type based at least in part on an association with a second device. The first device can select a key based at least in part on the association with second device. The first device can encrypt a payload to be included in a physical layer protocol data unit (PPDU) frame. The first device can determine a PPDU frame type based at least in part on an association with a second communication device. The first device can obfuscate the field of the MAC header. The first device can scramble the encrypted payload using a service field value. The first device can transmit the PPDU frame to the second device.

    Abstract: Methods, systems and apparatuses for negotiating mapping between traffic flows and different links by an access point (AP) multi-link device (MLD) and non-AP MLD are described. An AP MLD may transmit an initial request for a first limited mapping. A non-AP MLD may change to the first limited mapping. The non-AP MLD may register one or more high priority traffic flows and may change to a second mapping accommodating the high priority traffic flows on at least one additional link. The non-AP MLD and AP MLD may additionally exchange second and final mapping negotiation messages.
