The Complexity of Algebraic Algorithms for LWE

Matthias Johann Steiner

Arora & Ge introduced a noise-free polynomial system to compute the secret of a Learning With Errors (LWE) instance via linearization. Albrecht et al. later utilized the Arora-Ge p…

Solving Degree Bounds For Iterated Polynomial Systems

Matthias Johann Steiner

For Arithmetization-Oriented ciphers and hash functions Gröbner basis attacks are generally considered as the most competitive attack vector. Unfortunately, the complexity of Gröbn…

Arion: Arithmetization-Oriented Permutation and Hashing from Generalized Triangular Dynamical Systems

Arnab Roy, Matthias Johann Steiner, Stefano Trevisani

In this paper we propose the (keyed) permutation Arion and the hash function ArionHash over for odd and particularly large primes. The design of Arion is based on th…

Generalized Triangular Dynamical System: An Algebraic System for Constructing Cryptographic Permutations over Finite Fields

Arnab Roy, Matthias Johann Steiner

In recent years a new class of symmetric-key primitives over that are essential to Multi-Party Computation and Zero-Knowledge Proofs based protocols have emerged. To…

Schemes of Finite Expansion and Universally Closed Curves

Matthias Johann Steiner

In algebraic geometry there is a well-known categorical equivalence between the category of normal proper integral curves over a field and the category of finitely generated fi…
