Multilayer defense for connected cars.
Modern cars connect to external networks, offering safer, more convenient and enjoyable driving experiences. But this can also leave cars vulnerable to cyberattacks.
Hackers can access systems, but the risk doesn't stop there. They can even gain control of the car. To mitigate these risks, NXP delivers a comprehensive, multilayer approach for automotive security.
A vehicle's communication interfaces connect the car and its occupants to the outside world. These channels need to be protected to protect user privacy and vehicle safety. Our Secure Interfaces layer uses strong encryption and authentication to ensure that the vehicle is communicating with known (trusted) entities and that received data can be trusted.
Our Secure Gateway layer acts as a firewall that controls access from the external interfaces (such as the Internet) to the vehicle’s inner network, and that controls which nodes in the vehicle’s network can communicate with each other. As such, it provides domain isolation between for example, infotainment systems and safety-critical systems. It also converts between the different automotive communication protocols.
Our Secure Networks layer protects the communication over various in-vehicle networks against data manipulation and data theft. It includes intrusion prevention and intrusion containment capabilities.
ECUs continuously generate, process, exchange and store large amounts of potentially sensitive data—making them an attractive target for hackers. NXP’s broad portfolio of automotive microcontrollers and processors feature dedicated automotive (SHE and HSM) security modules that protect software from being manipulated and that support secure software updates and data protection.
Our “+1” layer for Secure Car Access provides traditional physical vehicle protection through anti-theft immobilizer and smart car access functions. Innovations in this area include new features like remote lock and unlock, passive start, remote vehicle monitoring and car access using a smartphone or smart key device.
Each connected component has its own specific security challenges. The 4+1 framework provides the right level of protection and countermeasures to individually address the security needs for each one. This structured approach delivers multiple levels of defense, from the vehicle’s perimeter to the individual electronic control units (ECUs), eliminating vulnerabilities.
Read how R155 and 21434 help the #automotive industry embrace security-by-design, as well as how NXP achieved compliance with the new standard.
S32K3 MCUs combine a robust safety architecture and multiple hardware safety mechanisms with a wide range of safety software, documentation, and technical support.
As the automotive industry increases its support of safety initiatives such as Vision Zero, the need for a robust V2X solution continues to grow.
This whitepaper focuses on the security aspects and needs of individual Electronic Control Units (ECUs). Includes a review of basic concepts, attack categories and example countermeasures and guidance on the level of protection needed for different domain ECUs.
A central gateway acts as a firewall between external networks and in-vehicle networks. It also plays an important role in the implementation of secure over-the-air firmware updates.
Vehicle Networking connects the computers or ECUs inside vehicles and the Cloud for sharing data and enabling services. As an industry leader in automotive solutions, NXP is enabling fast and secure vehicle networking applications.

The new standard ISO/SAE 21434 provides a well-defined cybersecurity framework and establishes cybersecurity as an integral element of engineering throughout the life of a vehicle, from concept through decommissioning. The policies and processes of NXP have been certified to comply with this standard.
NXP cybersecurity engineering processes are certified by TÜV SÜD to comply with the new automotive cybersecurity standard ISO/SAE 21434.
Connected vehicles can improve the user experience, enable new services and increase road safety—but they also pose new cybersecurity challenges.
