    Abstract: Disclosed are techniques for refreshing and updating user keys and user key lifetimes in a wireless communication system. In one aspect, a method of wireless communication is disclosed. The method includes generating, by an authentication node, a remote user key and a remote user key lifetime. The method further includes sending, from the authentication node to an anchor function node, the remote user key and the remote user key lifetime, and sending the remote user key lifetime to a remote wireless device via a relay wireless device.

    Abstract: This patent document describes, among other things, techniques, and apparatuses for a security method of discovery in proximity-based services. In one aspect, a method of wireless communication is disclosed. The method includes transmitting, by a wireless device to a first network function, an encrypted and integrity-protected message, wherein the encrypted and integrity-protected message is encrypted using a first key that is derived from a second key, wherein the wireless device has established the second key using a communication with a second network function, and wherein the encrypted and integrity-protected message is obtained by encrypting and integrity-protecting a message.

    Abstract: Techniques are described to perform network relay security. Multiple methods and an apparatus are proposed to protect the sensitive communication information of users in network communication environment. This application proposes a mechanism for protecting roaming UE capability indication in UE initiated slice-based SoR from attacks such as bidding down attacks. An example communication method includes generating, by a communication device, a request information message that includes a request information to be encrypted by a key, wherein the key is selected from a plurality of key pairs known to the first network node and the communication device, wherein a portion of the request information is transparent to a second network node; and transmitting, from the communication device, the request message to a first network node through the second network node, wherein the request message comprises a key identifier and a user identifier.

    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: 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.
