CESG Seminar: Hardware Trojans Begone: Inspiring Trust in Outsourced IC Fabrication

February 3, 2017 @ 4:10 am - 5:10 pm

Room 222 Civil Engr. Building (CVE)

Dr. Siddharth Garg

Abstract: Only a few semiconductor foundries (“fabs”) have the capability to fabricate integrated circuits (IC) using state-of-the-art fabrication technology. Most chip design companies outsource fabrication to one of these advanced foundries, typically located off-shore. However, this comes at the expense of trust.

How can the designer ensure the integrity of the ICs fabricated by an untrusted foundry? Malicious modifications of an IC, so-called “hardware Trojans” have become a major source of concern for both defense agencies and contractors, and commercial IC design companies.

In this talk, I will discuss a new approach for inspiring trust in outsourced IC fabrication. The idea (referred to as “split fabrication”) is to leverage a second chip, fabricated at a low-end but trusted on-shore foundry, to guarantee the integrity of the high-end but untrusted chip.

We will discuss two different (and orthogonal ways) in which split fabrication can be deployed to inspire trust in outsourced IC fabrication: to deter malicious modifications, or to detect modifications in the field. Compared to prior art, these approaches are the first to provide formal security guarantee, even for arbitrary Trojan misbehavior.
