Cyber Threats Multiply With Commercial Chiplets

Opening the door to third-party chiplet makers requires new approaches, greater diligence, and a deeper focus on security.

The commercialization of chiplets will significantly boost the potential for attacks on hardware, requiring a much broader set of security measures and processes at every level of the supply chain, including traceability from initial design to end of life.

Much progress has been made in recent years on security measures, including everything from identifying unusual data traffic inside a chip to complex obfuscation techniques. But chiplets multiply the number of possible attack vectors, and the more chiplets in a design the harder it is to protect a device. There is more data being processed, moved, and stored, and more components are involved in making that happen.
