Abstract

This application relates to a communication method, apparatus, vehicle, and storage medium for an in-vehicle network, and pertains to the field of network communication technology. The method includes: acquiring a security verification schedule table, which records security verification messages and slave nodes to be verified; sending a security verification message to the slave node, the security verification message carrying a verification key; and receiving a security verification response message sent by the slave node. This improves the security of information transmission in the in-vehicle network.
