Vehicle and method of controlling the same

1. A vehicle comprising:

at least one memory configured to store at least one default Instruction Structure Key (ISK), a generated ISK, and a pin code of the vehicle; and

at least one processor,

wherein the at least one default ISK comprises a first default ISK and a second default ISK, and

wherein the at least one processor is configured to:

generate a random number using the first default ISK;

receive the second default ISK encrypted with the generated ISK generated based on the pin code; and

when the generated random number and a random number corresponding to the second default ISK are the same, determine the generated ISK as an encryption key for encryption communication of the vehicle,

wherein the at least one processor comprises a first processor and a second processor,

wherein the first processor is configured to:

receive a number A that is the random number generated by the second processor;

generate the generated ISK based on the number A; and

when the received number A and the random number corresponding to the generated ISK are the same, determine the generated ISK as a code for temporary use, and

wherein the second processor is configured to:

receive a number B that is the random number generated by the first processor;

generate 16 bytes based on the number B; and

when the received number B and the random number corresponding to the 16 bytes are the same, determine the generated ISK as a code for the encryption communication of the vehicle.

2. The vehicle according to claim 1 , wherein the generated ISK is configured to be generated by hashing the pin code of the vehicle to Secure Hash Algorithm (SHA) 256.

3. The vehicle according to claim 1 , wherein the random number corresponding to the generated ISK is the random number corresponding to the default ISK encrypted with the generated ISK generated based on the pin code.

4. The vehicle according to claim 1 , wherein the 16 bytes are values obtained by successively arranging 4 lower bytes of the number B.

5. The vehicle according to claim 1 , wherein, when the received number A and the random number corresponding to the generated ISK are not the same, the first processor is configured to restore the generated ISK to a previous value.

6. The vehicle according to claim 1 , wherein, when the received number B and the random number corresponding to the 16 bytes are not the same, the second processor is configured to restore the generated ISK to a previous value.

7. A method of controlling a vehicle that performs encryption communication using at least one default Instruction Structure Key (ISK), a generated ISK, and a pin code, the method comprising:

wherein the at least one default ISK comprises a first default ISK and a second default ISK, and

generating a random number using the first default ISK;

receiving the second default ISK encrypted with the generated ISK generated based on the pin code; and

when the generated random number and a random number corresponding to the second default ISK are the same, determining the generated ISK as an encryption key for encryption communication of the vehicle,

wherein the determining of the generated ISK as a code for the encryption communication of the vehicle comprises:

generating a number A that is the random number;

generating the generated ISK based on the number A;

when the generated number A and the random number corresponding to the generated ISK are the same, determining the generated ISK as a code for temporary use;

generating a number B that is a random number;

generating 16 bytes based on the number B; and

when the generated number B and the random number corresponding to the 16 bytes are the same, determining the generated ISK as the code for the encryption communication of the vehicle.

8. The method according to claim 7 , wherein the generated ISK is configured to be generated by hashing the pin code of the vehicle to Secure Hash Algorithm (SHA) 256.

9. The method according to claim 7 , wherein the random number corresponding to the generated ISK is the random number corresponding to the default ISK encrypted with the generated ISK generated based on the pin code.

10. The method according to claim 7 , wherein the 16 bytes are values obtained by successively arranging 4 lower bytes of the number B.

11. The method according to claim 7 , wherein the determining of the generated ISK as the code for temporary use comprises:

when the generated number A and the random number corresponding to the generated ISK are not the same, restoring the generated ISK to a previous value.

12. The method according to claim 7 , wherein the determining of the generated ISK as the code for the encryption communication of the vehicle comprises:

when the generated number B and the random number corresponding to the 16 bytes are not the same, restoring the generated ISK to a previous value.
