Abstract: This document describes methods, apparatus, and systems that relate to enable Authentication and Key Management for Application service for roaming users. In one example aspect, a method for wireless communication includes receiving, by a network device in a first network from a network device in a second network, a signal indicative of an authentication result related to a wireless device, wherein the signal includes a first key and an indication in case that the first network is different from the second network; and generating, by the network device, a key related information based on the signal.

Abstract: This disclosure generally relates to transferring encryption key to a VPLMN in wireless communication. Performed by first network element, the method includes: transmitting a query message to a second network element, to request an identification of a NF entity, wherein the query message comprises an identifier of a wireless device, and wherein the network function is an entity in the VPLMN for storing encryption keys; receiving, from the second network element, a response to the query message, the response comprising the identification of the NF entity; and transmitting, to the NF entity based on the identification of the NF entity, a first message comprising an encryption key, wherein the AF entity is located in the HPLMN or a DN external to the HPLMN and the VPLMN.

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: 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.
