Abstract

Systems, devices and methodologies for generating a vehicle identification hash value and verifying the integrity of the vehicle. The vehicle identification hash value is generated based on hashes provided by each vehicle component. The generated overall vehicle identification hash value may be dynamic and reflects changes that occur to the vehicle at the component level.

First claim

The invention claimed is:

1. A vehicle integrity verification system comprising: one or more vehicle components, each vehicle component having a hash value, a vehicle control unit in communication each vehicle component, the vehicle control module configured to query each vehicle component for its respective hash value and to generate an overall vehicle identity hash value, and a vehicle integrity unit for verifying the integrity of the vehicle by comparing the generated overall vehicle identity hash value with a known predetermined vehicle identity hash value so that in response to a match between the generated overall vehicle identity hash value and a known predetermined vehicle identity hash value, the vehicle is determined to be uncompromised z wherein the vehicle integrity unit comprises a vehicle information integrity module, the vehicle information integrity module further configured to determine that some or all of the vehicle information is compromised in response to a discrepancy between the generated vehicle identity hash value and a known predetermined vehicle identity hash value, and wherein the vehicle information integrity module is further configured to determine which of the information has been compromised by determining which component hash value is changed and which information is associated with the changed hash value and to discard the compromised information.

2. The vehicle integrity verification system of claim 1 , wherein the vehicle information integrity module located in the vehicle control module of the vehicle.

3. The vehicle integrity verification system of claim 1 , the vehicle information integrity module located remotely in one or more of a remote vehicle, a server, or a remote computer in wireless communication with the vehicle control module of the vehicle.

4. The vehicle integrity verification system of claim 1 , wherein the vehicle components comprise one or more electronic control units, and each control unit generate and send a hash value.

5. The vehicle integrity verification system of claim 4 , wherein the vehicle components further comprise a non electronic control unit component and the hash value for the non electronic control unit is component is extracted by the vehicle control unit using a physical unclonable function.

6. The vehicle integrity verification system of claim 1 , wherein in response to the generated overall vehicle identity hash value not matching the known predetermined vehicle identity hash value, the vehicle is determined to be compromised, and determines the particular vehicle component that is compromised.

7. The vehicle integrity verification system of claim 1 , wherein the hash value of each vehicle component is dynamic and changes in response to physical and functional alterations.

8. The vehicle information communication system of claim 1 , wherein the vehicle information integrity module transmits or stores the information that has not been compromised for further processing.

9. The vehicle information communication system of claim 1 , wherein the vehicle information integrity module further generates an alert that identifies the one or more compromised vehicle components.
