Improved algebraic cryptanalysis of QUAD, Bivium and Trivium via graph partitioning on equation systems [PDF]
, 2010 We present a novel approach for preprocessing systems of polynomial equations via graph partitioning. The variable-sharing graph of a system of polynomial equations is defined. If such graph is disconnected, then the corresponding system of equations can

A Practical Cryptanalysis of the Algebraic Eraser [PDF]
, 2016 We present a novel cryptanalysis of the Algebraic Eraser primitive. This key agreement scheme, based on techniques from permutation groups, matrix groups and braid groups, is proposed as an underlying technology for ISO/IEC 29167-20, which is intended ...

Toward A More Efficient Gröbner-based Algebraic Cryptanalysis [PDF]
, 2019 In this paper, we propose a new method to launch a more efficient algebraic cryptanalysis. Algebraic cryptanalysis aims at finding the secret key of a cipher by solving a collection of polynomial equations that describe the internal structure of the ...

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.

Practical Algebraic Cryptanalysis for Dragon-based Cryptosystems [PDF]
, 2010 Recently, the Little Dragon Two and Poly-Dragon multivariate based public-key cryptosystems were proposed as efficient and secure schemes. In particular, the inventors of the two schemes claim that Little Dragon Two and Poly-Dragon resist algebraic ...
