“…HTs can be inserted in 978-1-4799-1585-9/13/$31.00 ©20 13 IEEE specification and design phases [1], but it is more common to implant hardware Trojans during fabrication, assembly and packing phases [3]. Layout-level HTs change the width of metal wires, reassign metal layers or alter interconnect length.…”

We exploit transient and permanent error control methods to address Hardware Trojan (HT) issues in Network-on Chip (NoC) links. The use of hardware-efficient error control methods on NoC links has the potential to reduce the overall hardware cost for security protection, with respect to cryptographic-based rerouting algorithms. An error control coding method for transient errors is used to detect the HT induced link errors. Regarding the faulty links as permanently failed interconnects, we propose to reshuffle the links and isolate the HT -controlled link wires. Rather than rerouting packets via alternative paths, the proposed method resumes the utilization of partially failed links to improve the bandwidth and the average latency of NoCs. Simulation results show that our method improves the average latency by up to 44.7% over the rerouting approach. The reduction on latency varies from 20% to 41 % for three traffic patterns on a 5x5 mesh NoC. The impact of different HT locations on NoC links was examined, as well. Our method is not sensitive to HT locations and can improve the effective bandwidth by up to 29 bits per cycle with minor overhead.

“…Run-time approaches. These approaches monitor for unexpected changes in logical and side-channel behavior to detect Trojans, but do so after the IC has been deployed (e.g., [7], [8], [10], [18]). Resource overheads have been the main disadvantage of run-time monitoring [2].…”

“…Run-time approaches on the other hand can be utilized for the entire lifetime of the IC. Hence, any Trojan missed during test-time can be found if the Trojan ever gets activated (e.g., [7], [8]). Second, an IC with an inactive Trojan performs essentially the same functions as a Trojan-free IC.…”

The hardware Trojan threat has motivated development of Trojan detection schemes at all stages of the integrated circuit (IC) lifecycle. While the majority of existing schemes focus on ICs at test-time, there are many unique advantages offered by post-deployment/run-time Trojan detection. However, run-time approaches have been underutilized with prior work highlighting the challenges of implementing them with limited hardware resources. In this paper, we propose three innovative low-overhead approaches for run-time Trojan detection which exploit the thermal sensors already available in many modern systems to detect deviations in power/thermal profiles caused by Trojan activation. The first one is a local sensor-based approach that uses information from thermal sensors together with hypothesis testing to make a decision. The second one is a global approach that exploits correlation between sensors and maintains track of the ICs thermal profile using a Kalman filter (KF). The third approach incorporates leakage power into the system dynamic model and apply Extended Kalman Filter (EKF) to track IC's thermal profile. Simulation results using state-ofthe-art tools on 10 publicly available Trojan benchmarks verify that all three proposed approaches can detect active Trojans quickly and with few false positives. Among three approaches, EKF is flawless in terms of the 10 benchmarks tested but would require the most overhead.

“…For example, a path delay characterization approach was proposed in [7] which, while effective, suffers from considerable area overhead for modern designs with millions of paths [1]. The current sensor approach in [8] should also come with significant area and power overheads. Temperature-based Trojan detection is an unexplored avenue which should have lower overheads compared to previous run-time approaches since many electronic systems are already equipped with thermal sensors for dynamic thermal management (DTM).…”
