  • Publication number: 20240179517
    Abstract: Embodiments of this specification provide an application layer key generation method and apparatus. According to the method in the embodiments, a connection mode used when a Bluetooth connection to an external Bluetooth device is established is first determined, an application layer key generation function is determined according to the determined connection mode, a link layer dynamic parameter used at a link layer is obtained, an application layer key identifier agreed upon with the external Bluetooth device is obtained, and an application layer key is generated by using the application layer key generation function, the link layer dynamic parameter, and the application layer key identifier.

  • 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.

  • Patent number: 11240671
    Abstract: Disclosed herein are methods, systems, and media for providing Bluetooth connection between Bluetooth devices. One of the methods comprises: generating, by a first Bluetooth device, a code; encrypting the code to generate a first ciphertext in response to detecting that a Bluetooth connection is disconnected; generating, by the first Bluetooth device, a broadcast packet based on the first ciphertext, and broadcasting the broadcast packet to a second Bluetooth device; receiving a scanning request from the second Bluetooth device, the scanning request including a random private address; verifying the scanning request based on the random private address; sending, in response to verifying the scanning request, a scanning response to the second Bluetooth device based on the random private address in the scanning request; and establishing a Bluetooth connection with the second Bluetooth device in response to determining that a connection request from the second Bluetooth device is received.
