Abstract: This application provides a security authentication method and apparatus applied to Wi-Fi, to help prevent a password from being shared among a plurality of devices, and implement management of a second device by a first device. In the method, an access point AP receives a first password input by the first device, where the first password is a password preset before delivery; and when checking on the first password by the AP succeeds, the AP obtains a second password shared between the AP and the first device, and performs 4-way handshake with the first device based on the second password. The second password is a shared key between the first device and the AP. Then, the AP can receive a first request from the first device, and send a third password to the first device in response to the first request.

Abstract: A method includes sending a first orbital angular momentum (OAM) reference signal in a first beam direction. The first OAM reference signal is used to determine a second beam direction from the first beam direction. The method also includes receiving first indication information. The first indication information includes information about the second beam direction. The method also includes sending a second OAM reference signal in the second beam direction. The second OAM reference signal is used to determine antenna information and a second channel response of the second OAM reference signal. The method also includes receiving second indication information. The second indication information is determined based on the second channel response and the antenna information. The second indication information is used to determine a transmission manner. The transmission manner includes OAM wave transmission, plane wave transmission, or joint transmission of OAM and a plane wave.

Abstract: This application discloses a Wi-Fi security authentication method and a communication apparatus. In the method, an access point AP receives a first access request from a supplicant, where the first access request carries a first parameter, and the first parameter is a parameter generated by the supplicant based on a generator of a set cyclic group and a first random number; generates a second random number, generates a second parameter based on the second random number and the generator of the set cyclic group, and sends the second parameter to the supplicant; generates a second pairwise master key based on the second random number, the first parameter, the second parameter, and a first target random key; and performs a four-way handshake authentication procedure with the supplicant based on the first pairwise master key and the second pairwise master key.

Abstract: This application provides a security authentication method and apparatus applied to Wi-Fi. An access point AP negotiates, based on a password, a pairwise master key PMK with a first device based on a twin base password encrypted key exchange TBPEKE protocol, where the password is a shared key between the AP and the first device; and the AP performs a 4-way handshake with the first device based on the PMK. Therefore, in embodiments of this application, a PMK with a high entropy value can be generated by performing a TBPEKE procedure, so that the security authentication method provided in embodiments of this application can help resist an offline dictionary attack.

Abstract: A method and an apparatus for signal synchronization are disclosed. The method for signal synchronization includes: A self-synchronizing first terminal device broadcasts first synchronization information, determines whether the first terminal device and a second terminal device have implemented signal synchronization when receiving second synchronization information sent by the second terminal device, and determines, based on a determining result, whether to synchronize with the second terminal device. This reduces a probability of communication interruption caused by synchronization source switching by the first terminal device after the second terminal device performs synchronization by using the first terminal device as a synchronization source. The method for signal synchronization may be applied to scenarios such as the intelligent driving, intelligent connected vehicles, and internet of vehicles.

Abstract: Embodiments of this application provide a drop orientation control method and apparatus. A drop orientation control method includes controlling a first orientation generation device to capture a to-be-tested object and drive the to-be-tested object to rotate by a first angle around a first rotation axis. The method further includes controlling the first orientation generation device to transfer the to-be-tested object that rotates by the first angle to the second orientation generation device. Furthermore, the method includes controlling the second orientation generation device to capture the to-be-tested object from the first orientation generation device and drive the to-be-tested object to rotate around by a second angle a second rotation axis. Additionally, the method includes and controlling the second orientation generation device to release the to-be-tested object, to enable the to-be-tested object to drop onto a drop plate, where the first rotation axis and the second rotation axis are perpendicular to each other.

Abstract: A method for managing a resource object is disclosed. The method executed by a management system includes: adding a mapping relationship between a UUID of a newly discovered resource object and an FDN identifier of the newly discovered resource object to a resource object identifier mapping relationship table; receiving a first query request for a to-be-managed resource object that is sent by an application system, where the first query request is used to obtain an FDN identifier of the to-be-managed resource object; and returning the FDN identifier of the to-be-managed resource object to the application system. According to the method, the resource object in the SDN system can be managed by using the application system by slightly modifying a network management system in an existing network system and an application based on the network management system, thereby implementing smooth evolution of the existing network system to the SDN system.
