Abstract: This disclosure provides methods, devices and systems related multi-link wireless communication. A method may include establishing, between the first WLAN device and a second WLAN device, a multi-link association that enables a first wireless communication link and a second wireless communication link. The method may include determining a temporal key for the multi-link association. The method may include encrypting a first and second media access control (MAC) protocol data unit (MPDU) based on the temporal key. The method may include preparing a first frame including the encrypted first MPDU and a second frame including the encrypted second MPDU. The method may include assigning packet numbers from a set of sequential packet numbers to the first and second frames. The method may include transmitting the first frame over the first wireless communication link and the second frame over the second wireless communication link.

Abstract: Man-in-the-middle attacks on reference signals used for positioning a mobile device in a wireless network can be detected through time and/or angle consistency checks. Time consistency checks may be based on a consistency of peak location and/or power delay profile across multiple reference signals and/or across different signal types, for example. Angle consistency checks may be based on a consistency of an angle at which a reference signal is received across multiple reference signals and/or in comparison with an expected angle, for example. Embodiments may further include reporting detected attacks.

Abstract: Methods, apparatuses, and computer-readable storage medium for encrypting discovery messages are provided. An example method at a first UE may include obtaining a discovery message that is ciphered based on at least one of a ciphering key, a ciphering algorithm, or a first set of time parameters, where the discovery message is scrambled based on at least one of a scrambling key, a scrambling algorithm, or a second set of time parameters. An example method may also include descrambling the discovery message based on at least one of the scrambling key, the scrambling algorithm, or the second set of time parameters. An example method may also include deciphering the discovery message based on at least one of the ciphering key, the ciphering algorithm, or the first set of time parameters.

Abstract: A first network node may transmit, to a second network node, first information associated with granular user consent control. The first information may be further associated with a data processing task and a UE. The second network node may receive, from the first network node or the UE, second information associated with the granular user consent control. The second information may be further associated with the data processing task and the UE. The second network node may identify a user consent result associated with the data processing task and a user of the UE based on the granular user consent control. The user consent result may be further based on the first information or the second information. The second network node may transmit, to the first network node, the user consent result. Thereafter, the first network node may handle the data processing task based on the user consent result.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may receive, from a second wireless communication device, a discovery message that includes a service code. The first wireless communication device may verify the service code. The first wireless communication device may transmit, to the second wireless communication device, a connection message that includes a protected service code that is derived from the service code. Numerous other aspects are described.

Abstract: In an aspect, a network supporting client devices includes one or more network nodes implementing network functions. Such network functions enable a client device to apply a security context to communications with the network when the client device is not in a connected mode. The client device obtains a user plane key shared with a user plane network function implemented at a first network node and/or a control plane key shared with a control plane network function implemented at a second network node. The client device protects a data packet with the user plane key or a control packet with the control plane key. The data packet includes first destination information indicating the first network node and the control packet includes second destination information indicating the second network node. The client device transmits the data packet or control packet.

Abstract: Various aspects pertain to ways to securing a peer-to-peer communication link that serves to relay transmissions to/from a managed mobile network node. A first user equipment may identify a second user equipment that can communicate via a peer-to-peer wireless interface and serve as a relay between the first user equipment and a managed mobile network node. A relay session key material may be obtained from the managed mobile network node. A peer-to-peer communication link between the first user equipment and the second user equipment may be established or modified by, for example, securing the peer-to-peer communication link based on the relay session key material. A protocol data unit session may be established, over the peer-to-peer communication link, between the first user equipment and the managed mobile network node for secured transmissions there between.

Abstract: Enabling Ethernet Header Compression (EHC) for use with data sent within a Non-Access Stratum (NAS) control plane of a wireless communication network. In one aspect, a wireless communication device sends a signal to a wireless communication network indicating the device supports EHC for data transfer over a control plane. The device obtains a response from the wireless communication network indicating the wireless communication network supports EHC for data transfer over the control plane. The device then sends an Ethernet packet compressed using EHC to the wireless communication network over the control plane. The wireless communication device may be configured to send a request to the wireless communication network to use EHC before sending the Ethernet packet compressed using EHC. The device then sends the compressed Ethernet packet only if the request is granted. In another aspects, complementary EHC features are provided within a network component of the wireless communication network.

Abstract: In an aspect, a slave UE and a master UE each establish an attachment to a core network of a cellular communications system. The slave UE obtains security credentials configured to encrypt and decrypt traffic between the slave UE and the core network. A D2D connection is established between the slave UE and the master UE (e.g., tethering). One or more communication functions are offloaded from the slave UE to the master UE, including at least one communication function with the core network for maintaining the attachment of the slave UE to the core network. Application-layer data is relayed to/from the slave UE over the D2D connection. In an aspect, either the slave UE or the master UE may perform encryption and decryption of control plane signaling using the slave UE's security credentials.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a frequency associated with a synchronization signal block (SSB) associated with a base station. The UE may generate a security key associated with a handover of the UE based at least in part on the frequency associated with the SSB. Numerous other aspects are provided.
