“…The affected chip will give desired output in normal condition, but will leak sensitive information upon being triggered. More detailed analysis of hardware Trojans can be found in [16][17][18]. An FPGA-based design is less threatened to hardware Trojans as the entire design cycle can be completed inside the designer's laboratory.…”

Modern field programmable gate arrays (FPGAs) have evolved significantly in recent years and have found applications in various fields like cryptography, defense, aerospace, and many more. The integration of FPGA with highly efficient modules like DSP and block RAMs has increased the performance of FPGA significantly. This paper addresses the lesser explored feature of modern FPGA called as reconfigurable LUT (RLUT) whose content can be updated internally, even during runtime. We describe the basic functionality of RLUT and discuss its potential applications for security from both destructive and constructive point of view, highlighting the conflicted usage of RLUTs. Several use cases exploiting RLUT feature in security-critical scenarios (physical attacks related in particular) are studied in detail. The paper proposes design of stealthy hardware Trojans having zero payload overhead to highlight destructive applications which can be built using hardware Trojans. On the other hand, this paper also highlights several constructive applications based on RLUT features, starting from lightweight side-channel countermeasures to kill switch to prevent the FPGA hardware from environmental hazards and malicious attack attempts.

“…Nowadays, detection methods at home and abroad are mainly destructive testing, logic testing and side-channel analysis and the like. Because of its low cost and highly effectual detection side-channel analysis has become more mainstream detection method in the current [3]. For examples, the author used power signal to detect Hardware Trojan in circuit [4], the author used the thermal signal to achieve the Hardware Trojan detection [5], the author detected Hardware Trojan by detecting delay information in circuit [6], etc.…”

Abstract. For the problem of Hardware Trojan detection, we analyzed the statistical properties of the power side-channel signal, and proposed a Hardware Trojan(HT) detection method based on the power side-channel signal. We processed the power side-channel signal by the maximum margin criterion(MMC), and projected the power side-channel signal onto low-dimensional subspace. We extract signal's Characteristic vector sequence, and detect Hardware Trojan in IC chip through statistical processing and analysis. We did simulation experiments to verify by Monte Carlo, and detect Hardware Trojan in C7552 circuit. Experimental results show that at ±20% of the process noise we can detect Hardware Trojan that accounts for 0.028 percent of the circuit, and compared with the K-L transform, this method achieved a good experimental result.

“…For this reason, more and more research focus on the study of hardware Trojan detection. The most widely used detection methods can be classified into logic testing-based approaches and side-channel analysis-based approaches [4]. Logic testing-based approaches input test vectors to activate the Trojan and recognize its influence.…”

“…When threshold set as 10-4, it needs adding 16 dummy flip-flops into s38417 benchmark and 0.8% area overhead [5]. Side-channel analysis-based approaches can detect Trojan by comparing the side-channel parameter of pending test and Trojan-free ICs without triggering Trojan [4]. Side-channel analysis-based approaches has become the most widely used and effective technique [6].…”

Abstract. Hardware Trojan is easy to be embedded during IC's design and manufacturing. Mostly used Trojan detection technique based on side-channel approach need a Trojan-free instance, and could not ensure Trojan-free instance's consistent of schematic. With the help of scan chain, one of the widely used design for testability (DFT) technology, a novel approach is proposed to obtain the schematic of Application Specific Integrated Circuit (ASIC). It is verified and tested by formal verification and hardware simulation. This approach not only could help to obtain the Trojan-free instance which has the same schematic as the ordinary design, but also provide a new method to other Hardware Trojan detection techniques.
