Algebraic attacks using SAT-solvers

open access: yesGroups – Complexity – Cryptology, 2010
An algebraic attack on a cryptosystem consists of transforming the problem into the solution of a system of polynomial equations, usually over a finite field. The paper ``Algebraic attacks using SAT-solvers'' discusses different ways to efficiently transform the polynomial system into a logical clause.

RAFA: Redundancies-assisted Algebraic Fault Analysis and its implementation on SPN block ciphers

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2023
Algebraic Fault Analysis (AFA) is a cryptanalysis for block ciphers proposed by Courtois et al., which incorporates algebraic cryptanalysis to overcome the complexity of manual analysis within the context of Differential Fault Analysis (DFA).

Reevaluating Graph-Neural-Network-Based Runtime Prediction of SAT-Based Circuit Deobfuscation

open access: yesCryptography, 2022
Logic locking is a technique that can help hinder reverse-engineering-based attacks in the IC supply chain from untrusted foundries or end-users. In 2015, the Boolean Satisfiability (SAT) attack was introduced.

On Cryptographic Attacks Using Backdoors for SAT

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2018
Propositional satisfiability (SAT) is at the nucleus of state-of-the-art approaches to a variety of computationally hard problems, one of which is cryptanalysis. Moreover, a number of practical applications of SAT can only be tackled efficiently by identifying and exploiting a subset of formula's variables called backdoor set (or simply backdoors ...

Noise‐based logic locking scheme against signal probability skew analysis

open access: yesIET Computers & Digital Techniques, 2021
Due to integrated circuit (IC) production chain globalisation, several new threats such as hardware trojans, counterfeiting and overproduction are threatening the IC industry. So logic locking is deployed to hinder these security threats.

Peek into the Black-Box: Interpretable Neural Network using SAT Equations in Side-Channel Analysis

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2023
Deep neural networks (DNN) have become a significant threat to the security of cryptographic implementations with regards to side-channel analysis (SCA), as they automatically combine the leakages without any preprocessing needed, leading to a more ...
