TLDR
The threat of hardware Trojan attacks is analyzed; attack models, types, and scenarios are presented; different forms of protection approaches are discussed; and emerging attack modes, defenses, and future research pathways are described.Abstract:Â
Security of a computer system has been traditionally related to the security of the software or the information being processed. The underlying hardware used for information processing has been considered trusted. The emergence of hardware Trojan attacks violates this root of trust. These attacks, in the form of malicious modifications of electronic hardware at different stages of its life cycle, pose major security concerns in the electronics industry. An adversary can mount such an attack with an objective to cause operational failure or to leak secret information from inside a chip-e.g., the key in a cryptographic chip, during field operation. Global economic trend that encourages increased reliance on untrusted entities in the hardware design and fabrication process is rapidly enhancing the vulnerability to such attacks. In this paper, we analyze the threat of hardware Trojan attacks; present attack models, types, and scenarios; discuss different forms of protection approaches, both proactive and reactive; and describe emerging attack modes, defenses, and future research pathways.read more

Ace: adaptive channel estimation for detecting analog/RF trojans in WLAN transceivers
TL;DR: A defense method capable of detecting hardware Trojans (HTs) in the analog/RF circuitry of wireless local area network (WLAN) transceivers and employs an adaptive approach to robustly isolate possible HT activity from channel and device noise, thereby exposing the Trojan's presence.

TAAL: Tampering Attack on Any Key-based Logic Locked Circuits
Ayush Jain,Ziqi Zhou,Ujjwal Guin +2 more
TL;DR: In this article, the authors proposed a TAAL attack based on implanting a hardware Trojan in the netlist, which leaks the secret key to an adversary once activated, and introduced the models for both the combinational and sequential hardware Trojans that evade manufacturing tests.
