Abstract: In one embodiment, a processor of a vehicle predicts a state of the vehicle using a behavioral model. The model is configured to predict the state based in part on one or more state variables that are available from one or more sub-systems of the vehicle and indicative of one or more physical characteristics of the vehicle. The processor computes a representation of a difference between the predicted state of the vehicle and a measured state of the vehicle indicated by one or more state variables available from the one or more sub-systems of the vehicle. The processor detects a malicious intrusion of the vehicle based on the computed representation of the difference between the predicted and measured states of the vehicle exceeding a defined threshold. The processor initiates performance of a mitigation action for the detected intrusion, in response to detecting the malicious intrusion of the vehicle.

Abstract: In one embodiment, a vehicle having a plurality of network interfaces communicates with a first communication network via a first one of the network interfaces. The vehicle receives performance data regarding the first communication network and one or more other communication network, wherein the received performance data is associated with a particular location. The vehicle determines in advance of arriving at the particular location that the vehicle should switch from communicating with the first communication network to communicating with a selected one of the one or more other communication network, based on the received performance data. At the particular location, the vehicle switches from communicating with the first communication network via the first network interface to communicating with the selected communication network via a second one of the plurality of network interfaces.
