Sequentially Triggering “Time-Bomb” Trojan into Hardware Wired Microsequencer
Authors: ,
Abstract: This paper presents an analysis of a sequential Triggered “Time Bomb” hardware Trojan (HT). Major
security concerns have been rising up since malicious modification of hardware or fabrication IC can lead to an
altered functional behavior, potentially with disastrous consequences in safety-critical applications. Due to the
stealthy nature of the hardware Trojans the conventional design and time verification and post manufacturing
testing cannot be readily extended. There are a large number of possible instances and operating modes for the
hardware Trojans in a digital system. Since the hardware Trojan insertion can modify the functionality of the
digital integrated circuit (IC), alter its behavior, generate denial of service (DoS), the HT threats should be
analyzed with maximum importance through the entire lifecycle of the IC.
