1. A method for receiving data between controllers in a vehicle network, the method comprising:
- receiving, from a controller, data codes including a length value of data codes;
extracting the length value of data codes from the received data codes;
extracting a position information value of the received data codes from a the second to last received data code;
extracting a random number from the last received data codes;
calculating a length value of the received data codes and a position information value of the received data codes;
comparing the calculated length and position information values of the received data codes with the extracted length value and position information value; and
converting an arrangement of the received data codes into an arrangement of data codes which the controller in the vehicle network recognizes, using the extracted length and position information values, when the calculated length and position information values are equal to the extracted length and position information values, respectively,wherein the calculating of the length and position information values of the received data codes includes calculating the length and position information values of the received data codes by inputting the extracted random number into an encryption function, andwherein the comparing of the calculated length and position information values of the received data with the extracted length and position information values of the data codes includes disregarding the received data codes and not performing a subsequent process, when the calculated length and position information values of the received data codes are different from the extracted length and position information values of the data codes, respectively.

Abstract
A method for transmitting data between controllers in a vehicle network includes transmitting a first data code including an identification number. A second data code is transmitted including a length value of data codes to be transmitted. Data codes are transmitted by using the length value of the data codes to be transmitted. A random number and a position information value of the data codes to be transmitted are included in last and previously transmitted data codes.
