Information technology – we define broadly as being systems based on digital hardware and software – has gained central importance for many new automotive applications and services.On the production side we observe that the cost for electronics and IT is approaching the 50% threshold of all manufacturing costs.One aspect of modern IT systems has hardly been addressed in the context of automotive applications: IT security. Security is concerned with protection against the manipulation of IT systems by humans. After a brief review of the evolution in the last five years of the IT security in the automotive environment, we will see the state of art of the security features of the automotive microcontrollers.laslty it will be presented an hardware module that ensure the privacy aspect, of the IT security, in a bus communication in an automotive environment.
