Multiplierless Design of Very Large Constant Multiplications in Cryptography
Levent Aksoy, Debapriya Basu Roy, Malik Imran +2
This brief addresses the problem of implementing very large constant multiplications by a single variable under the shift-adds architecture using a minimum number of adders/subtrac…
Hardware Obfuscation of Digital FIR Filters
Levent Aksoy, Alexander Hepp, Johanna Baehr +1
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 intell…
High-level Intellectual Property Obfuscation via Decoy Constants
Levent Aksoy, Quang-Linh Nguyen, Felipe Almeida +4
This paper presents a high-level circuit obfuscation technique to prevent the theft of intellectual property (IP) of integrated circuits. In particular, our technique protects a cl…
Side-Channel Attacks on Triple Modular Redundancy Schemes
Felipe Almeida, Levent Aksoy, Jaan Raik +1
The interplay between security and reliability is poorly understood. This paper shows how triple modular redundancy affects a side-channel attack (SCA). Our counterintuitive findin…
