500			_aCars sold today are computers on wheels, with dozens of embedded chips running millions of lines of code. Modern automobiles host more than 80 ECUs, which contain and implement a total of up to 100 million code lines to control safety-critical functionality. This fact and the close inter-connectivity of automotive ECUs open up new possibilities to attack these systems which impair the safe operation of the vehicle. So it is important to secure the information exchanged between these ECUs. We divide the ECUs into ve categories: Powertrain Control unit, Vehicle safety, Comfort, Infotainment, and Telematics. In Vehicle safety, there comes a need for faster encryption algorithms as it is mandatory that these algorithms should work accordingly. The response time from the Air Bag Unit ECU and ABS can't be less than a particular threshold. Also the messages from these ECUs should be encrypted. There comes a need for an encryption algorithm that meets the timing requirements. This project proposes an idea of encrypting the messages, from the vehicle safety ECU category, with an algorithm that meets compatible timing requirements. Based on the analysis of various algorithms, the one with smaller execution time and which is suitable for the CAN frame is selected for Encryption. CAN interface will be used for message simulation and CAPL scripting will be used for implementation and verication of Data Encryption Standard(DES) algorithm.
