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…
Compactness of Hashing Modes and Efficiency beyond Merkle Tree
Elena Andreeva, Rishiraj Bhattacharyya, Arnab Roy
We revisit the classical problem of designing optimally efficient cryptographically secure hash functions. Hash functions are traditionally designed via applying modes of operation…
Interpolation by Different Types of Quantum Channels Using Conic Programs
Arnab Roy, Saikat Patra
We have found conic programs for getting different types of quantum channels as outputs of interpolation problems. Afterwards, we have generalized our results for getting channels…
Binary matrix factorization on special purpose hardware
Osman Asif Malik, Hayato Ushijima-Mwesigwa, Arnab Roy +2
Many fundamental problems in data mining can be reduced to one or more NP-hard combinatorial optimization problems. Recent advances in novel technologies such as quantum and quantu…
Ising-based Consensus Clustering on Specialized Hardware
Eldan Cohen, Avradip Mandal, Hayato Ushijima-Mwesigwa +1
The emergence of specialized optimization hardware such as CMOS annealers and adiabatic quantum computers carries the promise of solving hard combinatorial optimization problems mo…
