Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay user equipment (UE) may establish a sidelink unicast link with a remote UE via a sidelink signaling interface. The relay UE may identify configuration information for an adaptation layer of the sidelink signaling interface, the configuration information including at least one of a remote UE identifier associated with the sidelink unicast link for a relay service, bearer identifier information identifying one or more bearers between the remote UE and a network entity for the relay service, a radio link control (RLC) channel mapping between a bearer identifier and one or more RLC channels, or data routing information associated with the relay service. The relay UE may relay communications between the remote UE and the network entity based at least in part on the configuration information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a relay UE, a first message comprising a first freshness parameter, an identity of the UE, and authentication information, where the authentication information is used by a network node to authenticate the UE with security context information of the UE. The UE may derive a relay key for security establishment between the UE and the relay UE based on the first freshness parameter, a set of key generation parameters, and a shared key with the network node. The UE may derive a relay session key for security establishment between the UE and the relay UE based on the relay key, a first nonce of the UE, and a second nonce of the relay UE. Numerous other aspects are described.

Abstract: Aspects of the disclosure relate to mechanisms for securely communicating broadcast information related to cell access within a secure cell. The broadcast information may be encrypted using a cell-specific broadcast key that may be derived from a broadcast root key that is refreshed periodically. A wireless communication device may obtain the broadcast root key via a secure connection with a provisioning server or core network node within a core network maintaining the broadcast root key or a long term key from which the broadcast root key may be derived. The cell-specific broadcast key may be derived using a key derivation function of the broadcast root key and at least cell identifying information associated with the secure cell.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for encrypting paging information transmitted to a user equipment (UE) in a paging message. In one aspect, a base station (BS) encrypts paging information and transmits a paging message to one of a UE or another BS for transmission to the UE. The paging message includes the encrypted paging information. A UE receives the paging message from a BS including the encrypted paging information. The UE decrypts the encrypted paging information to identify paging information, and determines whether to communicate with the BS based on the paging information. The paging information may be encrypted and the encrypted paging information decrypted based on information configured or obtained during at least one of a registration procedure or a radio access network (RAN)-based Notification Area Update (RNAU). Confidentiality of paging information in paging messages may thereby be improved.

Abstract: Aspects of the present disclosure describe scrambling of information for wireless communications to prevent deciphering or altering by unintended recipients. An example method may include generating, by a first device, a scrambling key based on at least one of a freshness parameter or a private key. The private key is known by the first device and a second device. The method also includes scrambling a payload based on the scrambling key at a physical layer. A packet includes the payload for wireless transmission from the first device to the second device via a shared channel.

Abstract: Techniques and apparatus for protecting sequence numbers used in authentication procedures are described. One technique includes receiving, from a network, an authentication request comprising at least a random challenge. After receipt of the authentication request, a synchronization parameter is generated based at least in part on a key shared by the network and the UE, the random challenge, and a first message authentication code (MAC). The synchronization parameter and the first MAC are transmitted to the network in response to the authentication request.

Abstract: Techniques for secure control plane communications between a User Equipment (UE) and a gNB are provided. A RAN network entity decides to handover a UE from a source base station (BS) to a target BS, wherein the RAN network entity controls a plurality of BSs including at least one of the source BS or the target BS, and wherein at least a portion of a control plane (CP) protocol layer is implemented at the target BS. The network entity generates at least one key specific to the target BS, based on a master key and a freshness parameter, the master key associated with the network entity. The network entity transmits an indication of the at least one key to the target BS, wherein the target BS exchanges control signaling with the UE based on the CP protocol layer using the at least one key.

Abstract: A gateway device detects a trigger associated with a device and, in response, identifies an application service associated with the device, obtains a traffic network policy associated with the application service, and obtains a network access token based on the traffic network policy. The network access token facilitates validating and/or mapping a downlink data packet obtained at the gateway device in user-plane traffic that is destined for the device. The network access token is sent to an entity in control-plane signaling. Subsequently, the gateway device obtains a downlink data packet including the network access token. The gateway device verifies the network access token and/or maps the downlink data packet to the device using data obtained from the network access token. The network access token may be removed from the downlink data packet before the downlink data packet is sent to the device according to the mapping.

Abstract: Aspects of security schemes (e.g., integrity protection, encryption, or both) are described. A measure of access stratum security can be realized without overhead associated with establishing and/or maintaining the per-cellular-device access stratum security context at a Cellular Internet of Things (CIoT) base station (C-BS). A gateway (e.g., a CIoT Serving Gateway Node (C-SGN)) may derive a first key. The first key may be only known to the C-SGN. The C-SGN may derive a second key from the first key and a parameter unique to the C-BS. The C-SGN may also derive a third key from the second key and an identity of a cellular device. The C-SGN may send the second and third keys to the C-BS and cellular device, respectively. Small data messages encrypted and/or integrity protected by the cellular device may be decrypted and/or verified by the C-BS.
