Abstract

A prevention device for operating a vehicle running record is provided. The device includes a cluster controller that is configured to convert a received and stored accumulated running distance of the vehicle from a cluster of the vehicle to generate a plurality of different distributed secret pieces. In addition, a plurality of other controllers are configured to receive and store each of the plurality of distributed secret pieces from the cluster controller.

Claims

a plurality of other controllers configured to receive and store each of the plurality of distributed secret pieces from the cluster controller.

2. The prevention device of claim 1, wherein the cluster controller is configured to convert the accumulated running distance into the plurality of distributed secret pieces using a predetermined polynomial expression.

3. The prevention device of claim 2, wherein the predetermined polynomial expression calculates a plurality of different values based on numbers allocated to the plurality of other controllers, and the plurality of different calculated values are the plurality of distributed secret pieces.

4. The prevention device of claim 3, wherein the predetermined polynomial expression (f(x)) is

f(x)=s+a₁x+a₂x²+ . . . +a_m-1x^m-1

wherein, the a₁, a₂, . . . , a_m-1 represents any integer, the x represents numbers allocated to the plurality of other controllers, respectively, and the s represents the accumulated running distance.

5. The prevention device of claim 1, wherein the cluster controller is configured to transmit a first random value and first authentication information to the plurality of other controllers, respectively, along with the plurality of distributed secret pieces,

the first random value is a specific value which is determined by a random scheme, and

the first authentication information is information obtained by encrypting the first random value using an encryption algorithm and an encryption key.

6. The prevention device of claim 5, wherein the plurality of other controllers are each configured to:

generate second authentication information using the encryption algorithm and the encryption key using the first random value as an input;

compare the second authentication information with the first authentication information; and

store the received distributed secret pieces when the second authentication information and the first authentication information correspond with each other.

7. The prevention device of claim 1, wherein when an engine of the vehicle is turned on, each of the at least two of the plurality of other controllers are configured to transmit a second random value and third authentication information to the cluster controller along with the stored distributed secret pieces,

the second random value is a specific value which is determined by a random scheme, and

the third authentication information is information obtained by encrypting the second random value using an encryption algorithm and an encryption key.

8. The prevention device of claim 7, wherein the cluster controller is configured to:

generate fourth authentication information using the encryption algorithm and the encryption key using the second random value as an input;

compare the fourth authentication information with the third authentication information; and

convert the received distributed secret pieces into the accumulated running distance when the fourth authentication information and the third authentication information corresponds with each other.

9. The prevention device of claim 8, wherein the cluster controller is configured to inform a vehicle user of when the converted accumulated running distance and the accumulated running distance stored in the cluster controller are different from each other.

10. The prevention device of claim 1, wherein when the cluster controller is to be replaced or reprogrammed to reset the accumulated running distance,

each of the at least two of the plurality of other controllers is configured to transmit a third random value and fifth authentication information to the cluster controller along with the stored distributed secret pieces,

the third random value is a specific value which is determined by a random scheme, and

the fifth authentication information is information obtained by encrypting the third random value using an encryption algorithm and an encryption key.

11. The prevention device of claim 10, wherein the replaced or reprogrammed cluster controller is configured to:

generate sixth authentication information using the encryption algorithm and the encryption key using the third random value as an input;

compare the sixth authentication information with the fifth authentication information; and

convert the received distributed secret pieces into the accumulated running distance and set the converted accumulated running distance as a new running record when the sixth authentication information and the fifth authentication information correspond with each other.

12. A prevention method of operating a vehicle running record, comprising:

converting, by a controller, a received and stored accumulated running distance of the vehicle from a cluster of the vehicle to generate a plurality of different distributed secret pieces; and

storing, by a plurality of other controllers, each of the plurality of distributed secret pieces.

13. The method of claim 12, further comprising:

converting, by the controller, the accumulated running distance into the plurality of distributed secret pieces using a predetermined polynomial expression.

program instructions that convert a received and stored accumulated running distance of the vehicle from a cluster of the vehicle to generate a plurality of different distributed secret pieces; and

program instructions that control a plurality of other controllers configured to receive and store each of the plurality of distributed secret pieces.

17. The non-transitory computer readable medium of claim 16, further comprising:

program instructions that convert the accumulated running distance into the plurality of distributed secret pieces using a predetermined polynomial expression.

18. The non-transitory computer readable medium of claim 17, wherein the predetermined polynomial expression calculates a plurality of different values based on numbers allocated to the plurality of other controllers, and the plurality of different calculated values are the plurality of distributed secret pieces.

19. The non-transitory computer readable medium of claim 17, wherein the predetermined polynomial expression (f(x)) is
