Hardware Obfuscation of Digital FIR Filters

2022 25th International Symposium on Design and Diagnostics of Electronic Circuits and Systems (DDECS), 2022
A finite impulse response (FIR) filter is a ubiquitous block in digital signal processing applications. Its characteristics are determined by its coefficients, which are the intellectual property (IP) for its designer. However, in a hardware efficient realization, its coefficients become vulnerable to reverse engineering.

Hardware Trojan Detection and Mitigation in NoC using Key authentication and Obfuscation Techniques

Emitter: International Journal of Engineering Technology, 2022
Today's Multiprocessor System-on-Chip (MPSoC) contains many cores and integrated circuits. Due to the current requirements of communication, we make use of Network-on-Chip (NoC) to obtain high throughput and low latency.

LifeLine for FPGA Protection: Obfuscated Cryptography for Real-World Security

Transactions on Cryptographic Hardware and Embedded Systems, 2021
Over the last decade attacks have repetitively demonstrated that bitstream protection for SRAM-based FPGAs is a persistent problem without a satisfying solution in practice.

Interlocking obfuscation for anti-tamper hardware [PDF]

Proceedings of the Eighth Annual Cyber Security and Information Intelligence Research Workshop, 2013
Tampering and Reverse Engineering of a chip to extract the hardware Intellectual Property (IP) core or to inject malicious alterations is a major concern. Digital systems susceptible to tampering are of immense concern to defense organizations. First, offshore chip manufacturing allows the design secrets of the IP cores to be transparent to the foundry

Address Obfuscation to Protect against Hardware Trojans in Network-on-Chips

Journal of Low Power Electronics and Applications, 2023
In modern computing, which relies on the interconnection of networks used in many/multi-core systems, any system can be critically subverted if the interconnection is compromised.

Program Obfuscation with Leaky Hardware [PDF]

, 2011
We consider general program obfuscation mechanisms using "somewhat trusted" hardware devices, with the goal of minimizing the usage of the hardware, its complexity, and the required trust. Specifically, our solution has the following properties: (i) The obfuscation remains secure even if all the hardware devices in use are leaky.

Development and Evaluation of Hardware Obfuscation Benchmarks [PDF]

Journal of Hardware and Systems Security, 2018
Obfuscation is a promising solution for securing hardware intellectual property (IP) against various attacks, such as reverse engineering, piracy, and tampering. Due to the lack of standard benchmarks, proposed techniques by researchers and practitioners in the community are evaluated by existing benchmark suites such as ISCAS-85, ISCAS-89, and ITC-99.

Hardware Obfuscation Based Watermarking Technique for IPR Ownership Identification

International Journal of Reconfigurable Computing, 2023
As the reuse of IP cores or the development of frequently used hardware modules is gaining more attention in the semiconductor industry, the misappropriation of the owner’s identity is a rising concern.

Stealthy Opaque Predicates in Hardware - Obfuscating Constant Expressions at Negligible Overhead

Transactions on Cryptographic Hardware and Embedded Systems, 2018
Opaque predicates are a well-established fundamental building block for software obfuscation. Simplified, an opaque predicate implements an expression that provides constant Boolean output, but appears to have dynamic behavior for static analysis.
