Design and Validation of CAN Protocol with Double Encryption for Electric Vehicle Applications

The security of the electric vehicle can be ensured by incorporating encryption features in sent/received data in the vehicle. By providing encryption to the data in the electric vehicle, it is ensured that it cannot be accessed by intruders. So, even if the vehicle is hacked no damage could happen for the vehicle. Here, two symmetric algorithms (RC6 and Blowfish) are used for encryption which provides double security and is named as double encryption. RC6 and Blowfish both are symmetric-cryptographic algorithm with variable block size and variable key size. Since both are symmetric algorithm there is no requirement of key-generation. The performance of proposed algorithms is validated using software and software simulation. Python programming is used in software simulation time calculation for encryption and decryption process. Hardware simulation is carried out by proteus with Arduino as controller. Results show that algorithms are implementable in hardware with minimum processing time. Hence the proposed algorithms are applicable for electric vehicle application where the security is ensured in practical environment.
