Algebraic Attacks on Block Ciphers Using Quantum Annealing
IEEE Transactions on Emerging Topics in Computing, 2022 This paper presents the transformation method of the system of algebraic equations describing the symmetric cipher into the QUBO problem. After transformation of given equations $f_0, f_1, \ldots, f_{n-1}$f0,f1,...,fn-1 to equations over integers $f ...

Stream/block ciphers, difference equations and algebraic attacks [PDF]
Journal of symbolic computation, 2020 In this paper we introduce a general class of stream and block ciphers that are defined by means of systems of (ordinary) explicit difference equations over a finite field. We call this class "difference ciphers".

High Order Side-Channel Security for Elliptic-Curve Implementations
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Elliptic-curve implementations protected with state-of-the-art countermeasures against side-channel attacks might still be vulnerable to advanced attacks that recover secret information from a single leakage trace.

Cryptanalysis of ARX-based White-box Implementations
Transactions on Cryptographic Hardware and Embedded Systems, 2023 At CRYPTO’22, Ranea, Vandersmissen, and Preneel proposed a new way to design white-box implementations of ARX-based ciphers using so-called implicit functions and quadratic-affine encodings. They suggest the Speck block-cipher as an example target.

Algebraic Attacks Galore! [PDF]
Groups – Complexity – Cryptology, 2009 Summary: This is the first in a two-part survey of current techniques in algebraic cryptanalysis. After introducing the basic setup of algebraic attacks and discussing several attack scenarios for symmetric cryptosystems, public key cryptosystems, and stream ciphers, we discuss a number of individual methods. The XL, XSL, and MutantXL attacks are based

Algebraic Attacks on Combiners with Memory [PDF]
, 2003 Recently, algebraic attacks were proposed to attack several cryptosystems, e.g. AES, LILI-128 and Toyocrypt. This paper extends the use of algebraic attacks to combiners with memory. A (k,l)-combiner consists of k parallel linear feedback shift registers (LFSRs), and the nonlinear filtering is done via a finite automaton with k input bits and l memory ...

Algebraic Description and Simultaneous Linear Approximations of Addition in Snow 2.0. [PDF]
, 2008 In this paper we analyse the algebraic properties over the field GF(2) of the addition modulo 2pn. We look at implicit quadratic equations describing this operation, and at probabilistic conditional linear equations.

Algebraic Persistent Fault Analysis of SKINNY_64 Based on S_Box Decomposition
Entropy, 2022 Algebraic persistent fault analysis (APFA), which combines algebraic analysis with persistent fault attacks, brings new challenges to the security of lightweight block ciphers and has received widespread attention since its introduction.

Strengthening Crypto-1 Cipher Against Algebraic Attacks
Journal of ICT Research and Applications, 2015 In the last few years, several studies addressed the problem of data security in Mifare Classic. One of its weaknesses is the low random number quality. This causes SAT solver attacks to have lower complexity.
