Abstract: Embodiments for securely determining a separation distance between wireless communication devices is provided. These embodiments include receiving a measurement request and a first random identifier from a first wireless communication device at a second wireless communication device. The embodiments also includes deriving a transient key using the first random identifier, a second random identifier (generated by the second device), and a pre-shared key. The first and second random identifiers, the pre-shared key, and the transient key derived therefrom are shared between the first and second devices, but are not known to any other devices. The embodiments further include encrypting measurement data exchanged between the two devices using the transient key, and using the encrypted measurement data to calculate and verify a separation distance between the devices. The embodiments thus prevent dishonest wireless communication devices from intercepting communications and spoofing a location of one of the two honest devices.

Abstract: Embodiments are disclosed for address changing schemes for a multi-link device in a wireless communications system. Some embodiments include a privacy enhanced (PE) access point (AP) multi-link device (MLD) that includes one or more affiliated APs operating on different links. The PE AP MLD can generate a first randomized OTA MLD address based at least on the MLD address of the PE AP MLD for a first affiliated PE AP (PE AP1). The PE AP MLD can transmit a first data transmission using the first OTA MLD address where the first data transmission includes an encrypted aggregated MAC service data unit (A-MSDU) subframe that includes the MLD address. The PE AP MLD can correlate the MLD address of the PE AP MPL with multiple addresses comprising: the first OTA MLD, a unique MLD address, and a Media Access Control (MAC) service access point (SAP) MLD address.

Abstract: Embodiments are disclosed for address changing schemes in a wireless communications system. Some embodiments include an access point (AP) that can establish two or more address profiles with a station (STA), establish a schedule for switching from a first address profile to a second address profile, where the first and second address profiles are of the two or more address profiles, and transmit a first data transmission using the first address profile. Some embodiments include switching from the first address profile to the second address profile based on the schedule, and transmitting a second data transmission using the second address profile. The schedule can be based on a randomized time synchronization function (TSF). The AP can establish a joint algorithm with the STA, and use the joint algorithm determine the first and the second address profiles as well as transition times for the schedule.

Abstract: After detecting an access-intent operation, an electronic device establishes a connection with a second electronic device using a communication protocol. The electronic devices exchange identifiers, and the second electronic device provides information specifying a preferred channel to use with a second communication protocol. Based at least in part on the preferred channel of the second electronic device and on communication contexts of the electronic devices, the electronic device selects a channel and transmits to the second electronic device information specifying the selected channel. The electronic device remotely accesses credential information based on the exchanged identifiers, and using the credential information, the electronic devices establish a secure connection via the selected channel using the second communication protocol. The electronic device determines a distance to the second electronic device using wireless ranging via the secure connection. When the electronic devices are proximate to each other, the electronic device can be unlocked.

Abstract: The present disclosure describes an electronic device that includes an antenna and an interface circuit. The interface circuit communicates, via the antenna, with a companion electronic device and/or a communication hub (e.g., an access point). The companion electronic device may communicate with the communication hub over a wireless network. During operation, the electronic device receives, from the companion electronic device or an archive electronic device, network-state information including an identifier of the companion electronic device, an identifier of the communication hub, or timing-synchronization information for beacons from the communication hub. In some embodiments, the network-state information may further include a channel associated with the connection. Moreover, the electronic device may disable communication via a first communication technique (e.g., Bluetooth) and enable communication via a second communication technique (e.g., WiFi). Furthermore, the electronic device may associate with the communication hub on the wireless network based on the network-state information.

Abstract: A method, station and computer readable storage medium used to perform opportunistic roaming procedures. A station joined to a basic service set (BSS) of an access point (AP) performs a method including determining a roam profile for the station, the roam profile indicating at least one of available operating bands or available APs for the station, determining a first value associated with a network parameter of the joined AP, determining at least one roam candidate AP having a second value associated with the network parameter corresponding to the roam candidate AP, wherein the first and second values are a received signal strength indicator, determining whether a predetermined criteria value is satisfied based upon the first and second values, wherein the predetermined criteria value is a minimum difference between the first value and second value and roaming to the roam candidate AP when the predetermined criteria value is satisfied.
