Example systems and method are disclosed for vehicle network gateway protection. An example disclosed method to protect a vehicle includes managing state transitions of a gateway separating a telematic dongle and a vehicle data bus. The example method also includes, when the gateway is in a field state, blocking first requests from the telematic dongle. Additionally, the example method includes, in response to the gateway transitioning to the field state, blocking the first requests and second requests from the telematic dongle for a period of time.

Vehicle gateway network protection

A vehicle includes: receiver(s), a timer counting time, memory, and processor(s) configured to: receive a timestamped signal from a fob; compare the timestamp to a time window; reject the timestamp if the timestamp is outside the time window; expand the time window with the counted time; compute the time window as a trigonometric function of the counted time and a predetermined angle.

Expanding time window for remote commands

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.
