We recently received an NSF grant on “Employing Information Theoretic Metrics to Quantify and Enhance the Security of Hardware Designs”. The project will develop quantitative hardware security metrics that enable designers to precisely evaluate the security of the system. We do this by employing statistical measures on the amount of uncertainty and information flow that is present across different portions of the hardware. These metrics are oblivious to the types of variables under consideration. Thus, we can assess both functional security properties related to confidentiality and integrity as well as covert channels. Our metrics enable the characterization of portions of the system that are potentially vulnerable to attacks. And they determine the effectiveness of mitigation techniques on the overall security of the system. The end result is more secure hardware, which leads to safer and more secure computing devices.
