A new hardware implementation of the advanced encryption standard algorithm for automotive applications

Modern cars are no longer mere mechanical devices and they are dominated by a large number of IT systems that guide a wide number of embedded systems called Electronic Control Unit (ECU). While this transformation has driven major advancements in efficiency and safety, it has also introduced a range of new potential risks. After a brief introduction of the security in automotive environment we investigate how the automotive community approached this problem. In order to ensure some security aspects in automotive environment, it is needed a hardware implementation of the Advanced Encryption Standard (AES) algorithm with higher speed throughput than existing solutions. For this purpose, a new hardware implementation of this cryptographic algorithm is presented. The implementation results are compared with previous works.
