Provided are an information processing method and system, an electrical device, and an edge computing device. The method includes receiving at least one of preset information sent by an edge computing device or operation parameter information of the electrical device sent by the edge computing device; and controlling operation of the electrical device according to the at least one of the preset information or the operation parameter information. The preset information is preset information broadcast by an electronic tag on a preset object within the preset range of the electrical device. After the electronic tag broadcasts the preset information, the preset information is received by a base station and sent to the edge computing device by the base station. The operation parameter information is determined according to the preset information.

A method for protecting against cyber attacks in a communication network of a vehicle, including the steps of acquiring dominant voltage measurements; obtaining an electrical characteristic of nodes that transmit messages by acquiring consecutive groups of voltage measurements at receiving nodes and calculating a distribution thereof; calculating values of distribution statistics; calculating a cumulative voltage deviation for each value of statistic; and obtaining a voltage profile by adding the cumulative voltage deviations of each statistic, executing a malicious-node detection procedure and then executing a transmitting-node identification procedure including comparing the at least one characteristic parameter against all the corresponding characteristic parameters of all the messages, defining a range of variation of the characteristic parameter with respect to a given number of previous samples; and evaluating whether the value of the parameter falls within the range of variation of one of the messages and identifying as malicious the node that transmits the message.

An electronic doorbell can include an outer housing configurable to couple to a building. The doorbell can also include a camera coupled to the outer housing and a microphone coupled to the outer housing. The doorbell can also include a button coupled to the outer housing. The electronic doorbell can be configurable to wirelessly communicate with an appliance located within the building.

A data transmission method and apparatus are provided. One example method involves establishing two tunnels between an access network device and a user plane function network element, where the two tunnels may be tunnels used for downlink data transmission or tunnels used for uplink data transmission. When communicating with the user plane function network element, the access network device may transmit two data packets. In this way, when one data packet is lost, the receive end may further receive the other data packet.

Disclosed are systems, methods, and devices for communicating a source of a 10SPE wake. Such a communication may be performed over a low-pin count hardware interface of a 10SPE physical layer (PHY) module having a split arrangement. A controller side of a 10SPE PHY may perform a local or remote 10SPE wake forward in response to a communicated source of a wake. Also disclosed is a digital interface for operatively coupling a PHY controller to PHY transceiver over a low-pin count connection, where the digital interface includes circuitry for checking the integrity of circuitry of the digital interface.

A system management bus link, a method and apparatus for determining the pull-up resistance thereof, and a device. The system management bus link comprises: a motherboard chip, a first pull-up resistor, and a second pull-up resistor. In the present invention, when resistance values of the first pull-up resistor and the second pull-up resistor satisfy configuring on a system management bus link any number of PSU power supplies that is smaller than or equal to a number threshold, a clock line in the link and a drive current in a data line are between a 0.5-times drive current threshold and a 0.9-times drive current threshold. Thus, the pull-up resistance of a motherboard end is optimized, which reduces the effect on the drive capacity of the number of PSU power supplies on a link, guarantees the drive capacity of the link, and improves link stability.
