摘要： Techniques for identity-based message integrity protection and verification between a user equipment (UE) and a wireless network entity, include use of signatures derived from identity-based keys. To protect against attacks from rogue network entities before activation of a security context with a network entity, the UE verifies integrity of messages by checking a signature using an identity-based public key PKID derived by the UE based on (i) an identity value (ID) of the network entity and (ii) a separate public key PKPKG of a private key generator (PKG) server. The network entity generates signatures for messages using an identity-based private key SKID obtained from the PKG server, which generates the identity-based private key SKID using (i) the ID value of the network entity and (ii) a private key SKPKG that is known only by the PKG server and corresponds to the public key PKPKG.

摘要： A device implementing a system for multipath connection management may include first and second local communication interfaces, and a processor configured to establish a primary connection for communicating between the first local communication interface and a first remote communication interface of an other device, and a secondary connection for communicating between the second local communication interface and a second remote communication interface. The processor may be configured to transmit application and control data over the primary connection and concurrently transmit a copy of control data over the secondary connection. The processor may be configured to determine that a degradation of the quality of the primary connection is attributable to the other device. The processor may be configured to switch the secondary connection to the first local communication interface and the second remote communication interface. The processor may be configured to transmit a copy of the application and control data over the secondary connection.

摘要： The subject technology receives, at a local device, a requested camera format based on specifications of a display associated with a remote device. The remote device and the local device are devices participating in a video conference. The requested camera format includes a first resolution. Camera formats supported by a camera associated with the local device are determined. If a second resolution of a first camera format matches among the supported camera formats matches with the first resolution, the first camera format is selected for capturing the video stream by the camera. Otherwise, a second camera format among the supported camera formats is determined for capturing the video stream so as to maximize a field of view of the video stream relative to other camera formats supported by the camera.

摘要： A device implementing dynamic redundancy may include at least one processor configured to receive, from another device, packet reception data corresponding to video data previously provided for transmission from the device to the other device and determine, based at least in part on the packet reception data, an amount of redundancy to apply to video data provided for transmission to the other device. The at least one processor may be further configured to determine, based at least in part on the amount of redundancy, an encoding scheme for applying the redundancy to the video data. The at least one processor may be further configured to apply the amount of redundancy to the video data based at least in part on the encoding scheme to generate redundant data items and provide the video data and the redundant data items for transmission to the other device.

摘要： A device implementing a system for packet loss management may include a memory and at least one processor configured to identify a plurality of categories of packets provided for transmission to an electronic device. The at least one processor may be further configured to determine a respective packet loss value for a respective category of the plurality of categories of packets. The at least one processor may be further configured to identify a particular category of the plurality of categories of packets for which the determined respective packet loss value satisfies a packet loss condition. The at least one processor may be further configured to adjust subsequent transmission of packets in the particular category of packets based at least in part on the packet loss condition being satisfied by the determined respective packet loss value for the particular category of packets.
