Abstract
A vehicle may receive a software update to be installed to a vehicle electronic control unit (ECU). The vehicle ECU may download a software update received from a server to a first storage; generate a nonce value associated with the software update; send to the server, a swap authorization request including the generated nonce value; receive a swap authorization including the nonce value and a command-and-control signature from the server; validate the signature and the nonce value from the swap authorization; and reboot using the first storage instead of a second storage when the recovered nonce value matches the generated nonce value.
