摘要： A method for key derivation for non-3GPP access. The method includes determining a particular non-3GPP access type, wherein the particular non-3GPP access type is one of N different particular non-3GPP access types (N>1), and each one of the N particular non-3GPP access types is associated with a unique access type distinguisher value. The method also includes generating (s604) a first access network key using a key derivation function and the unique access type distinguisher value with which the determined particular non-3GPP access type is associated, thereby generating a first access network key for the particular non-3GPP access type.

摘要： Systems and methods are disclosed herein that relate to verifying that a particular Application Function (AF) is authorized to use a particular AF ID in association with an Authentication and Key Management for Applications (AKMA) related procedure in a core network of a cellular communications system. In one embodiment, a method performed by an AKMA Anchor Function (AAnF) in a core network of the cellular communications system for generating a shared secret key for AKMA comprises receiving, directly or indirectly from an AF, a request for a shared secret key for AKMA, the request comprising an AF ID. The method further comprises determining whether the AF is authorized to use the AF ID and performing one or more actions based on a result of determining whether the AF (404) is authorized to use the AF ID.

摘要： A wireless device (14) receives, over an access stratum (18), a capability enquiry (24) that requests the wireless device (14) to transmit capability information (22) indicating one or more capabilities of the wireless device (14). After receiving the capability enquiry (24), the wireless device (14) generates a token (26) using one or more input parameters (28) and transmits the token (26). The one or more input parameters (28) include at least some part of the capability enquiry (24) and/or at least some of the capability information (22). In some embodiments, the token (26) is generated or transmitted based on a non-access stratum security context (30) at the wireless device (14). The wireless device (14) also transmits the capability information (22) over the access stratum (18).

摘要： Embodiments include methods for a user equipment, UE (510, 1010, 1100), to obtain security credentials for accessing a non-public network, NPN. Such methods include performing (610) a primary authentication procedure to, obtain a key KAUSF for secure communication between the UE and an onboarding network ON. Such methods also include receiving (620), from a unified data management, UDM, function, encrypted UE credentials for accessing the NPN, and decrypting (630) the encrypted UE credentials based on KAUSF. Other embodiments include complementary methods for UDM functions, authentication server functions (AUSF), and NPN provisioning servers, PVS, as well as UEs or network nodes configured to perform the exemplary methods.

摘要： A method performed by a network server is provided for authentication and key management for a terminal device in a wireless communication network. The method includes authenticating the terminal device during a primary authentication session for the terminal device. The method further includes responsive to a successful authentication of the terminal device, obtaining a first key. The method further includes generating bootstrapping security parameters. The parameters include a second key derived from the first key and a temporary identifier. The temporary identifier identifies the terminal device and the bootstrapping security parameters.

摘要： A first network node operating in a telecommunications network can receive an authentication request associated with a communication device requesting registration with the telecommunications network. The authentication request can include first subscriber information. The first network node can determine that the first subscriber information includes an anonymous identifier. Responsive to determining that the first subscriber information includes the anonymous identifier, the network node can determine an authentication procedure to be performed. The network node can receive information associated with the communication device as part of the authentication procedure. The network node can generate second subscriber information based on the information associated with the communication device.
