Validating vehicles traveling within specific regions

1. A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the processor to:

receive a registration corresponding to a vehicle computer, the registration including vehicle information;

generate a private key and a public key corresponding to the vehicle computer, wherein the private key and the public key are indicative of a specific region that the vehicle is allowed to travel;

store the public key and the vehicle information in a blockchain block;

transmit the private key to the vehicle computer;

transmit an authentication request to the vehicle computer;

receive, from the vehicle computer, a response including data proving that the vehicle computer includes confidential information, wherein the data does not convey the confidential information;

determine whether the response is valid based on the authentication request; and

transmit a warning to the vehicle computer when the response is not valid.

2. The system of claim 1 , wherein the authentication request comprises at least one point to be evaluated by the vehicle computer and the response comprises an evaluation of a polynomial using the at least one point.

3. The system of claim 1 , wherein the vehicle computer causes at least one vehicle system to actuate based on the warning.

4. The system of claim 1 , wherein the vehicle computer is disposed within a vehicle.

5. The system of claim 4 , wherein the vehicle comprises at least one of a land vehicle, an aerial vehicle, or an aquatic vehicle.

6. The system of claim 4 , wherein the processor is further programmed to:

determine whether the vehicle is authorized to travel within a specific region based on the response.

7. The system of claim 1 , wherein the private key comprises a polynomial.

8. The system of claim 1 , wherein the processor is further programmed to:

determine whether a communication link is established with the vehicle computer;

retrieve the public key and the vehicle information from the blockchain block based on a communication packet received from the vehicle computer; and

generate the authentication request based on at least one of the public key or the vehicle information.

9. The system of claim 1 , wherein the processor is further programmed to:

determine whether the response is valid by applying a blind evaluation of a polynomial protocol to the response.

10. A method comprising:

receiving a registration corresponding to a vehicle computer, the registration including vehicle information;

generating a private key and a public key corresponding to the vehicle computer, wherein the private key and the public key are indicative of a specific region that the vehicle is allowed to travel;

storing the public key and the vehicle information in a blockchain block;

transmitting the private key to the vehicle computer;

transmitting an authentication request to the vehicle computer;

receiving, from the vehicle computer, a response including data proving that the vehicle computer includes confidential information, wherein the data does not convey the confidential information;

determining whether the response is valid based on the authentication request; and

transmitting a warning to the vehicle computer when the response is not valid.

11. The method of claim 10 , wherein the authentication request comprises at least one point to be evaluated by the vehicle computer and the response comprises an evaluation of a polynomial using the at least one point.

12. The method of claim 10 , wherein the vehicle computer causes at least one vehicle system to actuate based on the warning.

13. The method of claim 10 , wherein the vehicle computer is disposed within a vehicle.

14. The method of claim 13 , wherein the vehicle comprises at least one of a land vehicle, an aerial vehicle, or an aquatic vehicle.

15. The method of claim 13 , further comprising:

determining whether the vehicle is authorized to travel within a specific region based on the response.

16. The method of claim 10 , wherein the private key comprises a polynomial.

17. The method of claim 10 , further comprising:

determining whether a communication link is established with the vehicle computer;

retrieving the public key and the vehicle information from the blockchain block based on a communication packet received from the vehicle computer; and

generating the authentication request based on at least one of the public key or the vehicle information.

18. The method of claim 10 , further comprising:

determining whether the response is valid by applying a blind evaluation of a polynomial protocol to the response.
