Abstract: The disclosure relates to a switchover method for an onboard redundancy system, an onboard redundancy system, a vehicle, and a storage medium, where the onboard redundancy system includes a first system and a second system that are communicatively coupled with each other. The method includes the following steps: simultaneously executing, by the first system and the second system, an input instruction in response to receiving the input instruction, where the first system is a preset primary system and the second system is a preset secondary system; performing, by the first system and the second system, a health monitoring operation during execution of the instruction; and autonomously executing, by the first system and the second system, a primary/secondary device switchover based on a health monitoring result.

Abstract: A transaction processing client based on a trusted execution environment is disclosed. The client verifies a server in a secure environment, obtains a public key of the server upon successful verification, generates a session key and encrypts the session key using the public key in the secure environment, transmits the encrypted session key to the server in a normal environment, encrypts pre-obtained transaction information using the session key in the secure environment, and transmits the encrypted transaction information to the server in the normal environment. The present disclosure effectively ensures the security of user login information and user private information.

Abstract: Systems and methods for providing capture functionality according to a security policy are provided. A request to capture content is received from a requesting application at a capture controller. The request is evaluated based on the security policy of the capture controller. Based on the evaluation, a determination is made as to whether the request is to be granted completely, denied, or granted subject to a constraint. Capture of the requested content is initiated via capture hardware or software if the request is granted completely or granted subject to the constraint.
