    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: A primary authentication procedure is triggered to derive an authentication key for a home network. The authentication key may be used for interworking between network types. For example, a home network primary authentication mechanism may be triggered for interworking from Evolved Packet System (EPS) to 5GS. When a user equipment (UE) moves between network types, the security context and authentication may be different or incompatible. For example, an authentication key may be missing, which may be needed for authentication in one of the network types. Authentication key support may be determined and registration/authentication may vary based on that support. When there is no support for the authentication key, a reauthentication process may be performed.
