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, methods, apparatuses, or computer-readable media for authenticating remote wireless communication devices. An authentication server function (AUSF) may send, to a unified data management (UDM), a request for authentication vectors (AV) in association with a remote wireless communication device seeking authorization to access a network via a relay wireless communication device. The request may include an indicator to indicate to the UDM to bypass storing information related to the AUSF. The AUSF may receive, from the UDM, the AV in response to the request.

Abstract: This disclosure generally relates to encrypted communication between terminal devices and service applications via a communication network. Such encrypted communication may be based on various hierarchical levels of encryption keys that are generated and managed by the communication network. Such encrypted communication and key management may be provided by the communication network to the terminal devices as a service that can be subscribed to. The various levels of encryption keys may be managed to improve flexibility of the communication network and to reduce potential security breaches.

Abstract: Embodiments of the prevent invention provide a network access authentication method and device. The method comprises: receiving an authentication request message sent by a first serving network, wherein the authentication request message carries a user equipment pseudonym identifier generated by a user equipment; determining whether a local user equipment pseudonym identifier is asynchronous with the user equipment pseudonym identifier generated by the user equipment; and obtaining, if the determination result is yes, an encrypted international mobile subscriber identity (IMSI) to carry out network access authentication on the user equipment. The embodiments of the present invention can solve the problem that a network access process in the related art does not provide a processing method for the case where the user equipment pseudonym identifier in the user equipment is asynchronous with the user equipment pseudonym identifier in a home network.
