  • Publication number: 20250112784
    Abstract: Embodiments of this specification provide signature authentication methods and apparatuses. A service private key for signature authentication is embedded in a trusted execution environment (TEE) of a terminal device in which a client device is located. In an implementation, a method includes the following. The client device sends a signature authentication request to a server. The client device receives authentication data information sent from the server. The client device encrypts the authentication data information by using a key that is pre-synchronized with the TEE. The client device sends encrypted authentication data information to the TEE. The client device then receives the signature data sent from the TEE and sends the signature data to the server.

  • Publication number: 20250112785
    Abstract: This specification provides methods, computer-readable media, and apparatuses for signature authentication. A server performs signature authentication on a terminal device. A service private key required for signature authentication is embedded in a trusted execution environment (TEE) of the terminal device. The TEE verifies a biological feature entered by a user, and after verification succeeds, the TEE completes a signature required by a signature authentication request.

  • Publication number: 20240137221
    Abstract: Computer-implemented methods, non-transitory, computer-readable media, and computer-implemented systems implementing a one-touch login service are described. Information about a first IP address is obtained from a verification request sent by an application client device. A token is sent to the application client device. Information about a second IP address is obtained from a number acquisition request sent by an application server. Whether the first IP address is the same as the second IP address is determined. If the same, based on a token carried in the number acquisition request, a mobile phone number of a terminal device in which the application client device is located is obtained and the mobile phone number is sent to the application server. If not the same, sending the mobile phone number of the terminal device to the application server is refused.

  • Publication number: 20240098488
    Abstract: A computer-implemented method for communication channel management performed by a wireless access point (AP) device is described. An original management frame that carries a target information element is constructed, where the target information element includes an information element related to communication channel management. When determined that one or more clients are connected to the AP device, for each of the determined clients: A destination address of the original management frame is set to a MAC address of the client. To obtain an encrypted management frame by using a key corresponding to the client, information in the target information element is encrypted. The encrypted management frame is sent in a WiFi network, so that a connected client in the WiFi network determines, based on the destination address, whether to process the encrypted management frame.
