The Discrete Logarithm Problem [PDF]

open access: yes, 2016
For large prime numbers p, computing discrete logarithms of elements of the multiplicative group (Z∕pZ)∗ is at present a very difficult problem. The security of certain cryptosystems is based on the difficulty of this computation. In this expository paper we discuss several generalizations of the discrete logarithm problem and we describe various ...

On the Complexity of Generalized Discrete Logarithm Problem

open access: yesCoRR, 2022
Generalized Discrete Logarithm Problem (GDLP) is an extension of the Discrete Logarithm Problem where the goal is to find $x\in\mathbb{Z}_s$ such $g^x\mod s=y$ for a given $g,y\in\mathbb{Z}_s$. Generalized discrete logarithm is similar but instead of a single base element, uses a number of base elements which does not necessarily commute with each ...

Cryptanalysing the critical group: efficiently solving Biggs's discrete logarithm problem [PDF]

open access: yesJournal of Mathematical Cryptology, 2009
Biggs has recently proposed the critical group of a certain class of finite graphs as a platform group for cryptosystems relying on the difficulty of the discrete log problem. The paper uses techniques from the theory of Picard groups on finite graphs to

The discrete logarithm problem modulo one: cryptanalysing the Ariffin–Abu cryptosystem [PDF]

open access: yesJournal of Mathematical Cryptology, 2010
The paper provides a cryptanalysis of the AAβ-cryptosystem recently proposed by Ariffin and Abu. The scheme is in essence a key agreement scheme whose security is based on a discrete logarithm problem in the infinite (additive) group ℝ/ℤ (the reals ...

DLP in semigroups: Algorithms and lower bounds

open access: yesJournal of Mathematical Cryptology, 2022
The discrete logarithm problem (DLP) in semigroups has attracted some interests and serves as the foundation of many cryptographic schemes. In this work, we study algorithms and lower bounds for DLP in semigroups.

Trace zero varieties in cryptography : optimal representation and index calculus [PDF]

open access: yes, 2014
The trace zero variety associated to an elliptic or hyperelliptic curve is an abelian variety defined over a finite field F_q. Its F_q-rational points yield a finite group, the trace zero subgroup of the degree zero Picard group of the original curve ...

Computing discrete logarithm by interval-valued paradigm [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
Interval-valued computing is a relatively new computing paradigm. It uses finitely many interval segments over the unit interval in a computation as data structure.

Variational Quantum Algorithm for Solving Discrete Logarithms [PDF]

open access: yesJisuanji kexue
The discrete logarithm problem is a significant challenge in number theory,and due to the difficulty of solving it,classical computers lack efficient algorithms for this task.As a result,the discrete logarithm problem is widely used in public key ...

SIDH Hybrid Schemes with Classical Component Based on the Discrete Logarithm Problem over Finite Field Extension [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2020
The concept of a hybrid scheme with connection of SIDH and ECDH is nowadays very popular. In hardware implementations it is convenient to use a classical key exchange algorithm, which is based on the same finite field as SIDH. Most frequently used hybrid
