    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.

    摘要: An Internet of Things (IoT) authorization method includes an IoT device that wirelessly communicates with a first electronic device and a second electronic device. A transmit distance of the second antenna is less than a transmit distance of the first antenna. When instructions stored in the memory are executed by the processor, the IoT device is configured to receive a first message indicating to add a shared control device for the IoT device; send, through the second antenna, a second message including device information of the IoT device; receive, in response to the second message, a third message including device information of the second electronic device; and send, through the first antenna, a fourth message including the device information of the second electronic device to the first electronic device.

    摘要: A subscriber authentication system prevents a change from being applied to a subscriber account until the subscriber approves of the change at the network core. The subscriber authentication system identifies one or more subscriber accounts for a network, each subscriber account being associated with a subscriber. The subscriber authentication system receives an indication that a change is requested for a subscriber account. The subscriber authentication system receives, within a network core, authentication information and data indicating whether the change is to be made to the subscriber account. The subscriber authentication system authenticates, within the network core, that the data was received from the subscriber based on the authentication information. The subscriber authentication system causes the change to be made based on the data indicating whether the change is to be made and the result of the
