Abstract: An authentication method for a target device, the method comprising authenticating, at an access network, a first identity of the target device for registering on the access network. In response to a successful authentication of the first identity by the access network, the method comprises executing, at the access network, a zero-knowledge proof (ZKP) protocol to authenticate a second identity of the target device for accessing a service provider; and, in response to a successful authentication of the second identity, granting, by the access network, access of the target device to the service provider.

Abstract: Embodiments of this application provide a packet transmission method and apparatus, and relate to the field of communication technologies. When the packet transmission method is applied, a first packet may be determined by using a first device, where packet fields of the first packet include an authentication identifier field, an authentication code field, and at least one candidate authentication field, and the authentication identifier field indicates a field that is in the at least one candidate authentication field and that corresponds to the authentication code field; and then the first packet is sent.

Abstract: A method for controlling a UAV in an environment includes receiving first and second sensing signals from a vision sensor and a proximity sensor, respectively, coupled to the UAV. The first and second sensing signals include first and second depth information of the environment, respectively. The method further includes selecting the first and second sensing signals for generating first and second portions of an environmental map, respectively, based on a suitable criterion associated with distinct characteristics of various portions of the environment or distinct capabilities of the vision sensor and the proximity sensor, generating first and second sets of depth images for the first and second portions of the environmental map, respectively, based on the first and second sensing signals, respectively, combining the first and second sets of depth images to generate the environmental map; and effecting the UAV to navigate in the environment using the environmental map.

Abstract: A robotic system is provided for performing rearrangement tasks guided by a natural language instruction. The system can include a number of neural networks used to determine a selected rearrangement of the objects in accordance with the natural language instruction. A target object predictor network processes a point cloud of the scene and the natural language instruction to identify a set of query objects that are to-be-rearranged. A language conditioned prior network processes the point cloud, natural language instruction, and the set of query objects to sample a distribution of rearrangements to generate a number of sets of pose offsets for the set of query objects. A discriminator network then processes the samples to generate scores for the samples. The samples may be refined until a score for at least one of the sample generated by the discriminator network is above a threshold value.

Abstract: A method for supporting multi audio tracks in wireless communication field, which uses multi stream media servers to share the assignment for supporting multi audio tracks. One stream media server receives one video data and multi audio data, but outputs only one determinate audio data; or one stream media server receives one video data and one audio data from multi audio data. User can select the required language by using portal website, and then connect to the stream media server for obtaining one video data and one audio data. The invention also provides a stream media server and a system for supporting multi audio tracks.
