India, Nov. 12 -- As vehicles become increasingly software-defined and connected, ensuring robust hardware cyber security is ever more critical. A modern car can contain 100 or more microcontrollers, each of which may introduce vulnerabilities that leave vehicles or even fleets open to dangerous remote hacking.

To address this growing challenge, Soitec and CEA have demonstrated how Fully Depleted Silicon-on-Insulator (FD-SOI) substrates can deliver intrinsic protection against the threat of fault injection attacks, identified as an increasing risk by automotive cybersecurity ISO/SAE 21434 standard setters.

Fault injection attacks occur when a hacker deliberately disrupts a chip's normal operation, for example with a voltage surge or las...
