Abstract: Presented are systems and methods for authorization of proximity based services. A first wireless communication device may send, to a second wireless communication device, a message to access a network via the second wireless communication device as a relay node, using at least one authentication and key management for applications (AKMA) service. The message may include an AKMA key identifier (A-KID) and a freshness parameter. The first wireless communication device may generate a validation token to validate against another validation token of the second wireless communication device. The first wireless communication device may generate the validation token using the freshness parameter and a proximity based service function (PBSF) key (KPBSF).

Abstract: This disclosure relates generally to a method, device, and system for ensuring security related to SCG and/or SN in a wireless network. One method performed by a wireless device is disclosed. The method may include: selecting a target PScell; the target PScell being associated with a target SN; determining whether the SW counter needs to be updated; in determination that the SW counter needs to be updated: incrementing the SW counter by a predefined value; and updating the security key based on the incremented SW counter and the base key; and transmitting, to a master node or the target SN, a first message requesting switching from a current PScell to the target PScell, the first message comprises at least one of: an indicator indicating that an update of the security key in the target SN is needed; or a value of the incremented SW counter.

Abstract: Techniques are described to perform network relay security. An example wireless communication method includes receiving, by a network device, a request message that includes an identifier associated with a first communication device; determining, by the network device in response to the receiving, that the first communication device is authenticated based on a local policy of the network device; and sending, by the network device in response to the determining, a message to a second communication device to relay to the first communication device, where the message indicates that the identifier is rejected by the network device for communication with the first communication device, or where the message indicates that the first communication device is triggered to send another identifier.

Abstract: This disclosure generally relates performing UE authentication and registration with the core network, and in particular, to supporting secure interactions between the UE and the target AMF when the UE is re-allocated to the target AMF from an initial AMF. The Access Network element stores a candidate AMF list, and optionally, the original Registration Request message from the UE. The initial AMF, once determines an AMF re-allocation is needed, instruct the UE to re-start the registration procedure with the core network according to the stored candidate AMF list. With the solutions provided in this disclosure, the message interactions between the UE and the target AMF are integrity protected, without the need to upgrade the UE and without using an indirect connection of the core network.
