摘要： A location privacy protection method includes generating an identifier update notification message to be sent to at least one access point, where the identifier update notification message includes a first identifier of a wireless terminal, to indicate that the identifier update notification message is to be sent by the wireless terminal. The identifier update notification message further includes second identifier information of the wireless terminal. The method further includes sending the identifier update notification message, so that the access point acquires a second identifier according to the second identifier information, and uses the second identifier as an identifier of the wireless terminal; and sending a subsequent message including the second identifier to the access point, to indicate that the subsequent message is sent by the wireless terminal.

摘要： A key configuration method includes acquiring, by a first device, a public key of a second device through a secure medium; sending, by the first device, information used for obtaining a shared key to the second device; and obtaining, by the second device, a shared key using a private key of the second device and the information that is used for obtaining a shared key. The first device obtains the shared key using the information used for obtaining a shared key or using a private key of the first device. The present disclosure ensures that the public key of the second device reaches the first device, avoids that an attacker masquerades as the second device to establish a secure connection with the first device, so that the attacker cannot listen to a message between the first device and the second device.

摘要： An information query method, including sending, by a first device, a data-excluded information query request frame, where the data-excluded information query request frame includes first control information and a first hash value; receiving, by the first device, a data-excluded information query response frame sent by a second device. The data-excluded information query response frame includes second control information, a second hash value, and an address of the second device. The method also includes sending, by the first device, a data-contained information query request frame to the second device when the first device determines that a third hash value is consistent with the second hash value, so that the second device responds to the data-contained information query request frame when receiving the data-contained information query request frame. Correspondingly, the present disclosure further provides a related device.
