Mitsubishi Electric develops cyber defense technology for connected cars

Mitsubishi Electric Corporation has developed a multi-layered defense technology that protects connected vehicles from cyber attacks by strengthening their head unit’s defense capabilities.

Vehicles with communication functions provide connections to the internet and/or mobile devices such as smartphones. The importance of cyber security is increasing because these vehicles are vulnerable to cyber attacks and even malicious remote control in extreme cases.

Mitsubishi Electric’s new multi-layered defense technology prevents cyber attacks 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.

Key features include:

  • Detects cyber attacks targeting the control of the vehicle and the automotive head unit. The developed technology reduces load processing by focusing on attack activities.

  • The new technology requires less than 10% of the time for a normal boot-up sequence compared with conventional technology. The developed 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.

  • Mitsubishi Electric’s new multi-layered defense technology achieves robust security of the vehicle by strengthening the security functions of the automotive head unit, the vehicle’s main link with the internet. The developed 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, for vehicle systems while requiring only limited machine resources.
