A link negotiation system includes a second device that determines a link configuration policy based on a status of a receiver of an interface of the second device, where the link configuration policy indicates an association relationship between a unidirectional logical lane and a unidirectional physical lane in a high-speed serial link between a first device and the second device, the unidirectional logical lane is a logical lane from the first device to the second device in the high-speed serial link, and the unidirectional physical lane is a physical lane from the first device to the second device in the high-speed serial link; and sends the link configuration policy to the first device.

Link negotiation system, method, and device

This application discloses a remote attestation method and an apparatus. The method specifically includes: A first network device receives encrypted information and first measurement information of a second network device through the second network device, where the encrypted information is information obtained by encrypting second measurement information of a third network device; the first network device determines, based on the first measurement information, that the second network device is system-trusted; and the first network device decrypts the encrypted information to obtain the second measurement information.

Remote attestation method and apparatus

A remote attestation mode negotiation method for a combined device and a related device, where the combined device includes at least a first unit. The method implemented by the first unit includes sending a mode negotiation request message to the remote attestation device; receiving a mode negotiation response message comprising a target remote attestation mode; and determining the remote attestation mode based on the mode negotiation response message. In this way, a target remote attestation manner to be used subsequently can be determined through negotiation between the combined device and the remote attestation device, to provide a data basis for subsequently and sequentially performing remote attestation on the combined device.

Remote attestation mode negotiation method for combined device and related device

A remote attestation method includes a first unit of a composite device obtains first measurement information of a second unit of the composite device. The first unit performs, based on the first measurement information, trustworthiness attestation on the second unit to obtain a first attestation result, and the first unit sends the first attestation result to a remote attestation device. In this way, the first unit in the composite device has a remote attestation function, and may perform trustworthiness attestation on another unit in the composite device to which the first unit belongs.

Remote attestation method and device for composite device

This application discloses a remote attestation mode negotiation method and apparatus. Before remote attestation is performed, automatic negotiation is performed between a to-be-verified network device and a server, so that the to-be-verified network device and the server can determine, through negotiation from remote attestation modes supported by both the to-be-verified network device and the server, a remote attestation mode used to subsequently perform remote attestation between the network device and the server, and there is no need to manually statically configure a remote attestation mode for the network device and the server, thereby greatly reducing labor costs of determining the remote attestation mode. In addition, when there are a large quantity of devices, the automatic remote attestation mode negotiation method also helps configure a remote attestation mode more flexibly.

An audio control circuit receives analog audio signals and digital audio signals via an audio signal input interface. The audio control circuit includes an audio codec chip, a first control circuit, a first switch circuit, a second control circuit, and a second switch circuit. The first control circuit obtains the analog audio signals from the audio signal input interface and converts the analog audio signals into first control signals to control the first switch circuit turned on and off. The second control circuit obtains the digital audio signals from the audio signal input interface and converts the digital audio signals into second control signals to control the second switch circuit turned on and off. The audio codec chip receives the analog audio signals in response to the first switch turned on and receives the digital audio signals in response to the second switch turned on.

Audio control circuit capable of processing both digital and analog audio signals

A clock signal generating circuit includes a crystal oscillator, a phase compensation circuit, a negative resistance compensation circuit, and a high pass filter circuit. The crystal oscillator generates a clock signal. The phase compensation circuit compensates a phase of the clock signal. The negative resistance compensation circuit filters phase noises of the clock signal. The high pass filter circuit filters low frequency noises of the clock signal.

Clock signal generating circuit and video signal processing circuit using same

A method for scheduling information includes receiving modulated first pilot information at a base station (BS). A power carried in the modulated first pilot information is obtained according to the modulated first pilot information. The BS schedules uplink or downlink information for a terminal according to the power carried in the modulated first pilot information.
