With the development of self-driving technology and public concerns about the safety of driverless cars, cybersecurity has become a top concern for automotive original equipment manufacturers (OEMs). Ensure the integrity of automotive systems and control of the vehicle to keep drivers, passengers and pedestrians safe. Along the way, cybersecurity is critical for automotive subsystems connected to the network, as well as image sensors for advanced driver assistance systems (ADAS) and driver monitoring.
Image sensors act as the eyes in the car, supporting ADAS functions such as lane departure warning, pedestrian detection and emergency braking. They help automotive systems assess their surroundings and monitor driver behavior. In the future, they will also help identify and authenticate car users and monitor the environment inside the car. However, image sensors also face cybersecurity threats and can become vulnerabilities in automotive systems.
A common cybersecurity threat is hacking. Hackers can remotely access image sensors, tamper with sensor data or obtain sensitive information. For example, a hacker could tamper with sensor data to trick vehicle systems into thinking there are no obstacles around or misidentifying road signs. This can cause the car to make poor decisions, endangering the safety of the driver and other road users.
In response to these threats, the United Nations Economic Commission for Europe (UNECE) working group issued UN-R155 Cybersecurity Regulation, which requires automakers to establish a cybersecurity management system (CSMS). The regulation requires automotive suppliers to ensure that all relevant components comply with the ISO 21434 cybersecurity standard. ISO 21434 is an international standard on automotive cybersecurity, covering cybersecurity management and risk assessment throughout the vehicle life cycle.
Onsemi is a company deploying cybersecurity features in ADAS image sensors. Their sensors have an authentication feature that can prove their authenticity to the host. In addition, the video data stream between the sensor and the host must use a message authentication code (MAC) to ensure integrity and prevent data tampering. Finally, sensor control and configuration data needs to be protected against tampering with specific key registers using the MAC. These security measures enable ON Semiconductor's image sensors to meet cyber security regulations.
In summary, cybersecurity is critical to the security of automotive image sensors. Following cybersecurity norms and standards, such as ISO 21434 and UN-R155, can ensure the security of image sensors and prevent them from becoming vulnerabilities in automotive systems. At the same time, suppliers and manufacturers also need to strengthen network security management to cope with the growing network security threats.
