Abstract

A security upgrade method, system, server, and vehicle-mounted terminal, the method comprising: a data plane server uses a first private key to sign an original upgrade package to obtain a security upgrade package; a control plane server generates an initial update including a download strategy for the security upgrade package For activity data, use a second private key different from the first private key to sign the initial upgrade activity data, and send the signed upgrade activity data to the vehicle-mounted terminal; the vehicle-mounted terminal uses the second public key to sign the upgraded activity The data is verified; if the verification is passed, the vehicle-mounted terminal downloads the security upgrade package according to the instructions of the download policy, and uses the first public key to verify the security upgrade package; if the verification passes, the vehicle-mounted terminal restores the The original upgrade package uses the original upgrade package to upgrade the vehicle-mounted system of the vehicle-mounted terminal, thereby reducing the security risk caused by server nodes being attacked and improving the security of the vehicle-mounted system upgrade.
