Abstract: An information processing method, a terminal device, and a network system include encrypting, by a first terminal, an authorization key based on a public key of a second terminal to obtain an authorization key ciphertext corresponding to the second terminal, and sending, by the first terminal, the authorization key ciphertext to the second terminal such that the second terminal decrypts the authorization key ciphertext based on a private key of the second terminal to obtain the authorization key, and then performs file decryption.

Abstract: An in-vehicle gateway communication method includes receiving a first message from a first in-vehicle device. An in-vehicle gateway identifies identification information in the first message, and matches the identification information with preset identification information stored in the in-vehicle gateway, and only when the matching succeeds, the in-vehicle gateway sends a second message, to indicate, using the second message, a second in-vehicle device to perform a target operation. When the identification information in the first message does not match the preset identification information stored in the gateway, the in-vehicle gateway does not send the second information to control the second in-vehicle device to perform the target operation. Therefore, identification information of a first message is set in an in-vehicle gateway of a vehicle.
