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: The present disclosure provides techniques that may be applied, for example, for providing network policy information in a secure manner. In some cases, a UE may receive a first message for establishing a secure connection with a network, wherein the first message comprises network policy information, generate a first key based in part on the network policy information, and use the first key to verify the network policy information.

Abstract: In embodiment methods for supporting pre-shared key (PSK) renegotiation, a user equipment (UE) may generate a request message including a first bootstrapping transaction identifier (B-TID), a first PSK namespace identifying a first bootstrapping procedure supported by the UE, and a first correlated PSK namespace indicating PSK renegotiation is supported by the UE for the first bootstrapping procedure, and send the request message to a network device. The network device may determine an indication of a PSK renegotiation for the first correlated PSK namespace in response to determining PSK renegotiation is required for the UE, generate a response message including the indication of the PSK renegotiation for the first correlated PSK namespace, and send the response message to the UE. In response, the UE may perform a bootstrapping procedure to obtain a second B-TID and second (i.e., new) session key (Ks).

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 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.

Abstract: Aspects of the disclosure relate to a system, method, and device for establishing a secure link for vehicle-to-vehicle (V2V) communication. A device may send a service announcement message to at least one other device via sidelink signaling. The service announcement message indicates a capability of the device to perform a service and includes at least a security certificate of the device. The device establishes a secure link with the at least one other device corresponding to the service by establishing a device key between the device and the at least one other device. The device then communicates service data for the service between the device and the at least one other device via the secure link based on the established device key. Other aspects, embodiments, and features are also claimed and described.

Abstract: Disclosed are systems and techniques for wireless communications. For example, a network entity (e.g., a Unified Data Management (UDM) network entity) can generate a user equipment (UE) parameters update (UPU) container. The UPU container includes a UE parameters update header information element (IE) and a UE parameters update list IE. The UE parameters update header IE includes UE parameters update header information. The UE parameters update list IE includes the UE parameters update header information of the UE parameters update header IE. The network entity can transmit the UPU container to a network device (e.g., a UE). The network device can generate, based on the UE parameters update list IE, a UPU message authentication code (MAC) for verifying integrity of the UPU container.

Abstract: Disclosed are systems and techniques for wireless communications. For instance, a process may include generating an anchor key based on an authentication server function key; associating a count value with the anchor key; generating a temporary device identifier based on the authentication server function key; generating an enhanced key identifier based on the count value, wherein the enhanced key identifier includes a portion of the temporary device identifier, wherein the portion of the temporary device identifier is less in size than an entire temporary device identifier; and transmitting the enhanced key identifier to a remote application.
