The increasing electronic content in vehicles presents new attack surfaces to hackers. Digital authentication can reduce the risk of theft and counterfeiting of genuine and approved components. In mission-critical automotive applications, such as advanced driver-assistance systems (ADAS) and electric vehicle (EV) batteries, low-quality counterfeits can introduce safety risks if their performance is degraded, compared with approved components. On the other hand, stolen components may not be calibrated to operate properly after installation in a different vehicle. By adding a single authentication IC, designers can authenticate a component with only one signal between an electronic control unit (ECU) and endpoint component. Endpoints that can benefit from authentication cover a broad range of applications in vehicles, such as optical cameras, headlamps, EV batteries, occupancy sensors, and even steering wheels, just to name a few.
