On-chip security circuit against hardware tampering
Computer security is a key issue for consumers, government agencies, and industry. While much of the focus has traditionally been centered on software, hardware-based security is necessary for a completely secure system. This technology describes a beacon circuit that provides hardware protection by alerting users to malicious tampering in design and fabrication. The beacon is integrated into the hardware itself and detects any changes in components or circuitry not intended by the user and provides alerts via unique power signature readouts. Beacon-based security provides a unified approach for protecting hardware from design to fabrication and beyond.
