Developing A Security Framework For Chiplet-Based Systems
Summary
Semiconductor Engineering is reporting on the emerging need for platform-level security frameworks in chiplet-based system architectures. The core requirement is that every security-relevant chiplet must carry a validated, consistent identity to ensure system integrity. This represents a significant design and supply chain challenge as heterogeneous integration of multi-sourced chiplets becomes standard practice in advanced semiconductor packaging.
Why It Matters
For manufacturers integrating advanced semiconductors into industrial control systems, robotics, and automation hardware, chiplet-based architectures introduce a new attack surface that did not exist in monolithic SoC designs. When a finished package may contain chiplets sourced from multiple foundries and IP vendors, verifying the provenance and integrity of each die becomes an operational supply chain problem, not just an EDA problem. A compromised or counterfeit chiplet in a motor controller or PLC could remain undetected through standard incoming inspection, since functional testing does not expose security vulnerabilities. Facilities relying on advanced industrial compute for safety-critical or OT-connected applications need to begin demanding chiplet identity attestation from their semiconductor suppliers now, before heterogeneous integration becomes the default architecture across the industry -- which leading-edge roadmaps suggest will happen within three to five years.
