Abstract

Leveraging 2.5D interposer technology, we advocate the integration of\nuntrusted commodity components/chiplets with physically separate, entrusted\nlogic components. Such organization provides a modern root of trust for secure\nsystem-level integration. We showcase our scheme by utilizing industrial ARM\ncomponents that are interconnected via a security-providing active interposer,\nand thoroughly evaluate the achievable security via different threat scenarios.\nFinally, we provide detailed end-to-end physical design results to demonstrate\nthe efficacy of our proposed methodology.\n
