Kalyna Block Cipher: From Design Space Exploration to ASIC Design
Carlos Gewehr, Levent Aksoy, Mariia Rodinko +2
The Kalyna block cipher is a Ukrainian cryptography standard, selected through a national competition held between 2007 and 2010 and approved in 2015. Although its software impleme…
Hardware-Efficient Compound IC Protection with Lightweight Cryptography
Levent Aksoy, Muhammad Sohaib Munir, Sedat Akleylek
Over the years, many techniques have been introduced to protect integrated circuits (ICs) from hardware security threats that emerged in the globalized IC manufacturing supply chai…
RESAA: A Removal and Structural Analysis Attack Against Compound Logic Locking
Felipe Almeida, Levent Aksoy, Samuel Pagliarini
The semiconductor industry's paradigm shift towards fabless integrated circuit (IC) manufacturing has introduced security threats, including piracy, counterfeiting, hardware Trojan…
CAC 2.0: A Corrupt and Correct Logic Locking Technique Resilient to Structural Analysis Attacks
Levent Aksoy, Muhammad Yasin, Samuel Pagliarini
Logic locking proposed to protect integrated circuits from serious hardware threats has been studied extensively over a decade. In these years, many efficient logic locking techniq…
KRATT: QBF-Assisted Removal and Structural Analysis Attack Against Logic Locking
Levent Aksoy, Muhammad Yasin, Samuel Pagliarini
This paper introduces KRATT, a removal and structural analysis attack against state-of-the-art logic locking techniques, such as single and double flip locking techniques (SFLTs an…
Multiplierless Design of High-Speed Very Large Constant Multiplications
Levent Aksoy, Debapriya Basu Roy, Malik Imran +1
In cryptographic algorithms, the constants to be multiplied by a variable can be very large due to security requirements. Thus, the hardware complexity of such algorithms heavily d…
