Abstract: A method performed by an authentication server (14) in a home network (3) of a user equipment (1), UE, for obtaining a subscription permanent identifier, SUPI. The method comprises: - receiving a subscription concealed identifier, SUCI, which comprises an encrypted part in which at least a part of the SUPI is encrypted, and a clear-text part which comprises a home network identifier and an encryption scheme identifier that identifies an encryption scheme used by the UE to encrypt the SUPI in the SUCI, - determining a de-concealing server (19) to use to decrypt the encrypted part of the SUCI; - sending the SUCI to the de-concealing server (19), and - receiving the SUPI in response. Methods performed by a UE and a de-concealing server are also disclosed. Furthermore, UEs, de-concealing servers, authentication servers, computer program (133) and a memory circuitry (12) are also disclosed.

Abstract: Core network equipment is configured for use in a core network of a wireless communication system. The core network equipment is configured to switch switching to using a new non-access stratum, NAS, security context between a user equipment and the core network equipment. The core network equipment is also configured to, during or in association with a handover procedure for handover of the user equipment, signal from the core network equipment that the new NAS security context between the user equipment and the core network equipment is to be used as a basis for an access stratum (AS) security context between the user equipment and radio access network equipment.

Abstract: Techniques for handling ciphering keys in a mobile station comprising a mobile equipment (ME) and a Universal Subscriber Identity Module (USIM) are disclosed. An example method includes obtaining a UMTS cipher key (CK), integrity key (IK), and ciphering key sequence number (CKSN) from the USIM, deriving a 128-bit ciphering key (Kc-128) from the CK and the IK, and storing the Kc-128 and the CKSN on the mobile equipment, separate from the USIM. The stored CKSN is associated with the stored Kc-128, so that the Kc-128's correspondence to the most current UMTS security context can be tracked. This example method applies to the generation and storage of a 128-bit ciphering key for either the packet-switched or circuit- switched domains. A corresponding user equipment apparatus is also disclosed.

Abstract: A method of authenticating a client to two or more servers coupled together via a communications network, wherein the client and a first server possess a shared secret. The method comprises authenticating the client to a first server using said shared secret, signalling associated with this authentication process being sent between the client and said first server via a second server, generating a session key at the client and at the first server, and providing the session key to said second server, and using the session key to authenticate the client to the second server.

Abstract: A method of generating a password for use by an end-user device (UE) ( 101 ) to access a remote server ( 103 ) comprises sending a request for access from the UE to the remote server, and sending to an authentication node ( 105 ) in the UE's home network ( 104 ) details of the request for access and the identity of the remote server. A HTTP Digest challenge is generated at the authentication node or the remote server using an algorithm capable of generating end-user passwords. The challenge includes details of the identity of the remote server and the identity of the UE. A password is generated and stored at the UE ( 101 ) based on the HTTP Digest challenge, the password being associated with the identity of the remote server ( 103 ) and the identity of the UE ( 101 ).

Abstract: A user equipment ("UE") can handle registrations of the UE in different wireless communication networks. The UE can obtain information indicating whether a Universal Subscriber Identity Module ("USIM") of the UE supports storing multiple different Non-Access Stratum ("NAS") security contexts of the UE associated with the different wireless communication networks. The UE can further determine whether the USIM supports storing the multiple different NAS security contexts of the UE associated with the different wireless communication networks based on the obtained information.
