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: Techniques are provided for medium access control header obfuscation. One example method includes a first device encrypting a data payload using a first encryption algorithm. The first device can encrypt a field of a medium access control (MAC) header using a second encryption algorithm, different from the first encryption algorithm. The first device can generate a data frame comprising the encrypted MAC header field and the encrypted payload. The first device can transmit the data frame to a second communication device.

Abstract: Systems, methods, and mechanisms for a privacy enhanced basic service set (BSS), including privacy enhancements for both access points and wireless stations as well as privacy enchantments for authentication, association, and discovery operations. Further, the systems, methods, and mechanisms disclosed may continue to support legacy wireless stations and are thus, backward compatible. A station may communicate with a legacy BSS of a wireless network to transition to a PE BSS of the wireless network. The station may receive, from the PE BSS of the wireless network, an encrypted beacon, wherein the encrypted beacon is decoded based on information received from the legacy BSS and perform, with the PE BSS of the wireless network, an encrypted handshake procedure to authenticate and associate with the PE BSS of the wireless network.

Abstract: Systems, methods, and mechanisms for a privacy enhanced basic service set (BSS), including privacy enhancements for both access points and wireless stations as well as privacy enchantments for authentication, association, and discovery operations. Further, the systems, methods, and mechanisms disclosed may continue to support legacy wireless stations and are thus, backward compatible. A non-associated PE station may receive, from a PE access point, one or more discovery beacons advertising PE BSSs hosted by the PE access point and transmit, to the PE access point, a request to setup pre-association security protection. The non-associated PE station may, upon setup of pre-association security protection, transmit, to the PE access point, a protected request frame and receive, from the PE access point, a protected response that includes PE access point parameters.
