摘要： 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.-

摘要： Fifth Generation (5G) standards specify use of a Subscription Concealed Identifier (SUCI) (i.e. a concealed identity) for a user equipment (UE) during initial registration, where the SUCI is derived from a Subscription Permanent Identifier (SUPI) of the UE. Given the identity concealment and use of different identities on different interfaces in a 5G network, maintaining subscriber state with a stateless network architecture may be challenging. Accordingly, one or more techniques and mechanisms are provided herein for subscriber management with a stateless network architecture in a 5G network, even without the need to maintain intermediate states of a UE in an external data store. The one or more techniques and mechanisms may be provided in relation to processing of Next Generation (NG) Application Protocol (NGAP) signaling messages at an access and mobility management function (AMF), and in particular, in relation to a registration procedure for the UE.

摘要： Embodiments of this application provide a device identifier access method and an apparatus, and relate to the field of communications technologies, so as to reduce a risk of privacy leakage caused by excessive access to a device identifier by an application program, and improve device security of a terminal. The method includes: receiving, by a terminal, request information for accessing a first device identifier by a target application; in response to the request information, determining, by the terminal, first access permission used when the target application accesses the first device identifier, where the first access permission includes one of the following: prohibiting access to the first device identifier, allowing access to a real value of the first device identifier, and allowing access to a dummy value of the first device identifier; and when the first access permission is allowing access to the dummy value of the first device identifier, returning, by the terminal, the dummy value of the first device identifier to the target application, where the dummy value of the first device identifier is obtained after anonymization processing is performed on the real value of the first device identifier.

摘要： In a home network of a communication system, wherein one or more cryptographic key pairs are provisioned for utilization by subscribers of the home network to conceal subscriber identifiers provided to one or more access points in the communication system, the method comprises provisioning one or more privacy managing entity identifiers for utilization by the subscribers when providing their concealed subscriber identifiers to the communication system. Each of the one or more privacy managing entity identifiers identify a given privacy managing entity in the communication system configured to de-conceal a given subscriber identifier.
