Trust Assurance for COTS IC

The commercial off-the-shelf (COTS) component based ecosystem provides an attractive system design paradigm due to the drastically shorter deployment cycle and reduced development cost compared to custom solutions. However, there is a growing concern of security vulnerabilities in COTS components arising from embedded malicious logic, or hardware Trojans. Existing trust-verification approaches are typically not applicable to COTS hardware due to the absence of golden models and lack of observability of internal signals. My research in this area involves the development of solutions for runtime Trojan-resilience using software-level alterations.
