    摘要: There is provided mechanisms for remote provisioning of a SIM profile to a subscriber entity. A method is performed by a remote SIM provisioning server. The method comprises obtaining a request from an MNO entity for generation of the SIM profile. The method comprises generating the SIM profile. The method comprises providing, to a storage entity, a key-value pair of the SIM profile. The key-value pair comprises a unique identifier comprising at least one profile specific element of the SIM profile as key and binding information of the at least one profile specific element as value. The unique identifier comprising at least one profile specific element of the SIM profile is represented by profile/subscription unique data elements for the SIM profile. The binding information of the at least one profile specific element is represented by an BID of the subscriber entity, ICCID of the SIM profile, IMSI, and an MNO identifier. The method comprises providing, to the subscriber entity requesting download of the SIM profile, the SIM profile.

    摘要: A method and an apparatus for controlling a data access right are disclosed. The method includes: receiving, by a first proxy node, a first request message from a request node, where the first request message includes an identity of the request node and an identifier of to-be-accessed data; determining a first encrypted ciphertext on a blockchain based on the identifier; determining, based on the identity, whether the request node has a right to read the first encrypted ciphertext; and if yes, initiating a right verification request for the request node to at least one second proxy node, and determining, based on a feedback result of the at least one second proxy node, provisioning of the first encrypted ciphertext. A proxy node is added to the blockchain network, so that a data source can freely grant or revoke the right of the request node without modifying a ciphertext, ensuring information security.

    摘要: Methods, systems, and devices for wireless communications are described for physical layer signature feedback to enhance security in wireless communications. A user equipment (UE) and a network entity may apply a physical layer signature, such as an artificial physical layer impairment, to one or more physical layer signals that may be measured to identify a physical layer signature of the associated physical layer signal. The UE, upon receipt of a physical layer signal, may check if the identified signal includes a physical layer signature of a set of valid physical layer signatures. If the received physical layer signature matches a valid physical layer signature, the UE may operate in accordance with procedures associated with the signal. If the received physical layer signature does not match a valid physical layer signature, the UE may transmit a message to the network entity that indicates an unmatched physical layer signature.

    摘要: The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. A method and an apparatus for enabling inter-device profile movement using only two devices without separately carrying out identity verification or ID authentication verification are provided. The method includes receiving an input for moving a first profile installed in a first terminal, deleting the first profile on a first eUICC, generating, for data including first profile information, digital signature data of the first eUICC, and displaying data including the first profile information and the corresponding digital signature data as a QR code on a screen of the first terminal.
