Abstract
A system and method for protecting a vehicle from theft includes monitoring transmissions over an in-vehicle network; determining, based on at least two of the content of at least one message, electrical characteristics of the transmission of the message, and the context of the vehicle, that an unauthorized device is connected to the in-vehicle network and is used to perform at least one of: stealing the vehicle, and bypassing security or access system of the vehicle. A system or method includes performing at least one of: recording and reporting information related to the unauthorized component, preventing or mitigating an attack on the vehicle, and preventing theft or unauthorized use of the vehicle.
Claims15
A method of protecting a vehicle from theft, the method comprising:
- monitoring transmissions over an in-vehicle network;
- determining, based on at least two of the content of at least one message, electrical characteristics of the transmission of the message, and the context of the vehicle, that an unauthorized device is connected to the in-vehicle network and is used to perform at least one of:
- stealing the vehicle, and
- bypassing security or access system of the vehicle;
- and
- performing at least one of:
- recording and reporting information related to the unauthorized component,
- preventing or mitigating an attack on the vehicle, and
- preventing theft or unauthorized use of the vehicle.
The method of any one of the preceding claims, wherein determining the unauthorized component is malicious is based on a state of the vehicle.
The method of any one of the preceding claims, wherein determining the unauthorized component is malicious is based on examining messages sent by the unauthorized component and identifying operations the unauthorized component attempts to perform.
The method of any one of the preceding claims, comprising preventing the unauthorized component from communicating over the network.
The method of any one of the preceding claims, comprising controlling or activating a component in the vehicle to thus protect the vehicle from the unauthorized component.
The method of any one of the preceding claims, comprising, based on matching the content of a message with a signature of a component, determining one of:
- a message appearing to originate from the component was indeed sent by the component, and
- an unauthorized component is connected to the in-vehicle network.
The method of any one of the preceding claims, wherein the signatures are received from a server.
The method of any one of the preceding claims, comprising determining the unauthorized component is used to perform at least one of:
- coding a key, unlocking a door of the vehicle and starting the engine of the vehicle.
The method of any one of the preceding claims, comprising determining the unauthorized component is physically connected to the in-vehicle network.
The method of any one of the preceding claims, comprising, based on at least one of:
- a command, a configuration element, an event, and a state or context of the vehicle, performing at least one of:
- authenticating the unauthorized component,
- ignoring the unauthorized component,
- removing a signature,
- creating a signature representing a new component, and
- calculating or recalculating a signature for a component.
Dependencies are inferred from the claim text.
