Securing autonomous driving.

The basis for the self-driving or autonomous vehicle is its networking with the environment and the cloud. Our radar systems or multipurpose cameras, as well as our microcontroller-based engine, transmission and battery control systems pave the way for autonomous driving. More than 70 such microcontroller-based systems can already be found today in an average mid-range vehicle, and the trend is on the rise.

But as each external "touchpoint" is added, the security threat increases, whether through manipulation, unauthorized access or data theft. Not least, the protection of privacy and protection against undesired route monitoring become an issue here. Infineon is one of the driving forces behind autonomous driving. We have been acquainted with all the relevant structures for many years. And we now bring together our decades of experience in security solutions with Infineon’s automotive quality competence to solve the newly arising challenges.

One essential requirement for autonomous driving in the future is data integrity. Its development needs the highest level of expertise.

Vehicle to vehicle (V2V)

In the future, vehicle-to-vehicle communication will lead to improved road traffic safety and efficiency. For example, drivers can be warned about potholes or accidents on their route.

Vehicle to infrastructure (V2I)

Vehicles can connect to traffic lights and other traffic control systems via WLAN and other wireless communication channels. Traffic conditions will thus be easier to check and congestion easier to avoid.

Vehicle to cloud (V2C)

In the future, more and more interaction processes will run via the cloud. The cloud makes it easier to transmit relevant and high-volume data – from software updates for on-board electronic systems to comprehensive services.


eCall is an emergency call system integrated into the vehicle. In the event of an accident, eCall will automatically transmit the vehicle's position and other critical data to the rescue services. The time it takes for the driver to get help will thus be dramatically reduced. In the European Union, eCall will be mandatory in new cars from 2018.

Car to Internet apps

Equipped with network reception, many cars already create simple plug and play interfaces to mobile information and communication technology devices. Special apps provide information, improve service or comfort and offer a broad extensive opportunities for new business and service models. Infineon’s chips such as for SIM cards will play a key role in connecting the automotive world with telecommunications services.

Our contribution for secure connected cars

We have decades of experience in the areas of vehicle safety and protection. Our know-how covers the technology as well as the software and processes for improving vehicle and data security. System understanding means that we never view protection merely as a product feature. It is the right mix of clear client and product identification, data encryption, storage security and manufacturer's proof of origin (original part authentication) that enable efficient and effective, hence systematic protection in the first place.

Our chip solutions deliver optimum protection through the combination of hardware security and encryption technology. As the market leader in trusted computing, and with decades of experience in the traditional high security chip card segment as well as a deep automotive quality understanding, we contribute valuable knowledge to the field of autonomous driving.

Infineon offers products and solutions with outstanding features:

  • Trustworthy security solutions
  • Extreme thermal endurance (-40°C to 105°C)
  • High reliability and quality in accordance with AEC-Q100
  • Long service life
  • Simple system integration

Our qualifications as a security partner for the autonomous vehicle:


We have pooled our extensive expertise from the Automotive and Security market to offer our customers scalable automotive security solutions

Broad offering

Scalable security products and solutions offer the right level of security and investment

Certified production

Infineon security chips are manufactured and personalized in accordance with audited and certified production processes

Proven quality

Industry-level solutions, some of which already meet the high quality standards (AEC-Q100) typically found in the automotive sector with enhanced product features (e.g. temperature range)

Treat yourself to our system knowledge. It's worth it.

Infineon's semiconductor and system solutions support the rapid and complex changes in the automotive industry. That's because we define security as the result of security processes along the entire value chain. It already begins in production: Infineon's development process for security controllers is certified according to common criteria, and its production processes are subject to certified audits. This stringent monitoring of security processes by third parties is the foundation for the excellent security and quality of the hardware security chips of Infineon.

As the market leader in M2M, we enable secure connectivity of today’s smart cars. In addition, we offer Trusted Platform Modules (TPM) that are able to securely protect and process confidential keys.

With these keys, car manufacturers (OEMs) and suppliers can add other encrypted security-critical data to the control units. As a result, there is no need for steps designed to protect key handling. Costs can thus be lowered and manufacturing security improved.

We have built up a deep understanding of security and industry during more than 25 years of our own research, but also as a partner for well-known customers.

You benefit from this system knowledge – because security creates value:

  • Improved quality and reliability
  • Development of new business and service models
  • Competitive edge
  • Creation of trust in the new opportunities
  • Protection of intellectual property and know-how
