A witch-hunt for trojans in our chips: on hardware-trojans and defenses

A witch-hunt for trojans in our chips
A Hardware Trojan (HT) is a malicious modification of the circuitry of an integrated circuit. A malicious chip can make a device malfunction in several ways. It has been rumored that a hardware trojan implanted in a Syrian air-defense radar caused it to stop operating during an airstrike, thus instantly minimizing the country’s situational awareness and threat response capabilities. In other settings, hardware trojans may leak encryption keys or other secrets, or even generate weak keys that can be easily recovered by the adversary. This article introduces a new trojan-resilient architecture, discusses its motivation and outlines how it differs from existing solutions. The full paper (Vasilios Mavroudis, Andrea Cerulli, Petr Svenda, Dan Cvrcek, Dusan Klinec, George Danezis) has been presented in several academic and industrial venues including DEF CON 25, and ACM Conference on Computer and Communications Security 2017.[…]
