Abstract: 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.

Abstract: 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.

Abstract: Embodiments of this application disclose a remote attestation mode negotiation method for a combined device and a related device. The combined device may include 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.

Abstract: Disclosed is a portal push method, which comprises: a broadband remote access server (BRAS) equipment acquiring a website identification list, after the BRAS equipment receives a hypertext transport protocol (HTTP) request message sent by a user terminal. The BRAS equipment determines whether to send portal pages to the user terminal according to whether the identification of a target website visited by the user client has a matched item in the list. The embodiments of the present disclosure further provide a corresponding BRAS equipment. The technical solutions of the embodiments of the present disclosure can reduce push times of invalid portals and improve portal push success rate.

Abstract: An integrated reductant supply system includes a reductant tank, a reductant dosing module selectively couplable to the reductant tank, an aftertreatment control module coupled to the reductant tank and in electrical communication with the reductant dosing module and a connector, and an integrated reductant supply system component. The aftertreatment control module is configured to control dosing of reductant from the reductant dosing module, and the connector configured to electrically couple to an equipment manufacturer component. The integrated reductant supply system component is coupled to the reductant tank and includes one or more of an ambient temperature sensor, a solenoid valve, a reductant level sensor, a reductant delivery line, a reductant return line, a coolant inlet line, a coolant return line, a filter, a mounting bracket, an AOS, or a wiring harness.

Abstract: A method and an apparatus for sending a key on a Wireless Local Area Network (WLAN) is provided. In a scenario where an Access Server is separate from an Access Controller, the Access Controller may send a master key of a specified WLAN station to the AC and trigger the AC to agree with the station on a transient key. The method includes: when receiving the master key of the WLAN station sent from an AAA server, searching a station information table for an IP address of an AC associated with the station; sending a message to the AC to instruct the AC to perform a 4-way handshake with the station to agree on a transient key, where the third message carries the master key of the station, a 4-way handshake triggering bit, and a MAC address of the WLAN station.
