Developing Automotive Grade SoCs
That Are Both Safe and Secure

BOS’s Safety & Security Architecture and Design

Advanced Driver-Assistance Systems (ADAS) and software-defined vehicles (SDV) drive
the emergence of powerful on-vehicle computing platforms.

This powerful host software functionality enhances customers’ experience and increases the level of automation.

But these benefits require increasingly advanced safety & security architectures to defend against cybersecurity vulnerabilities and threats. BOS’s safety & security architecture and design shown below meets these requirements.
