Developing A Security Framework For Chiplet-Based Systems

The article discusses the importance of developing a security framework for chiplet-based systems. In chiplet platforms, security must be addressed at the platform level to ensure every security-relevant chiplet has a validated identity. Two common provisioning patterns are described: externally provisioned identity and silicon-derived identity. The article emphasizes the need for chiplet identity to be policy-bound and discusses boot authentication, trust-chain infrastructure, securing die-to-die communication, and lifecycle security in chiplet systems. The focus is on ensuring secure communication, trust decisions, and lifecycle governance in multi-die chip systems.
