Abstract: A system and method of registration with AMF re-allocation. The system and method includes receiving, by an initial AMF from a wireless communication device via a RAN, a registration request comprising a first device identifier associated with the wireless communication device. The system and method includes determining, by the initial AMF, an identifier type associated with the first device identifier. The system and method includes generating, by the initial AMF, a reroute message comprising a second device identifier. The system and method includes originating, by the initial AMF to the wireless communication device, a security mode command message comprising a redirection criteria or an integrity negotiation algorithm, the security mode command message causes the wireless communication device to set the redirection criteria allowing the wireless communication device to accept a request message that is not integrity protected and return a security mode complete message to the initial AMF.

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.

Abstract: proviced is an authentication method based on a GBA, and the method includes: a BSF receives an initialization request message sent by a UE, wherein the initialization request message carries a first identifier of the UE, and the first identifier comprises at least one of the following: a SUCI, an identifier converted from the SUCI, and a TMPI associated with the subscriber identity; the BSF acquires an AV of the UE according to the first ID; the BSF completes GBA authentication with the UE according to the acquired AV. In this way, the privacy of the SUPI is protected for the UE, and the SUCI or the identifier converted from the SUCI is used to perform the bootstrapping process of the GBA, thereby improving the security of the GBA authentication process.

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.
