    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: This disclosure relates generally to a method, device, and system for ensuring security related to SCG 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, wherein the target SN is a member of a list of SNs, each SN in the list of SNs is associated with a SN counter; determining whether a SN counter associated with the target SN needs to be updated; in determination that the SN counter associated with the target SN needs to be updated, selecting a refreshed SN counter value and updating at least the SN counter associated with the target SN with the refreshed SN counter value; and transmitting, to the master node, a first message requesting switching from a current PScell to the target PScell.

    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: 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: 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).
