Mitsubishi creates multi-layer cyber defense technology for AVs

Mitsubishi Electric Corporation has developed a multi-layered defense technology to protect connected vehicles from cyberattacks by strengthening their head unit's defense capabilities. The technology will help realize more secure vehicle systems for vehicles equipped for connection to external networks.

Vehicles with communication functions provide connections to the internet and mobile devices such as smartphones. The importance of cyber security is increasing, said Mitsubishi, because these vehicles are vulnerable to cyberattacks and even malicious remote control.

The new multi-layered defense technology prevents cyberattacks through a variety of security features, including an intrusion detection system without high-load processing and a secure-boot technology that quickly verifies software integrity during the boot process.

The new technology requires less than 10 percent of the time for a normal boot-up sequence compared with conventional technology. A Fast Secure Boot technology enables faster and more secure boots that verify the integrity of the vehicle's software embedded in the automotive head unit.

According to Mitsubishi, the technology is adapted from multi-layered defense technology originally developed for critical infrastructure, such as systems for electric power, natural gas, water, chemicals, and petroleum.
