A new method for solving the elliptic curve discrete logarithm problem [PDF]

open access: yesGroups, Complexity, Cryptology, 2021
The elliptic curve discrete logarithm problem is considered a secure cryptographic primitive. The purpose of this paper is to propose a paradigm shift in attacking the elliptic curve discrete logarithm problem.

Quantifying the Leakage of Quantum Protocols for Classical Two-Party Cryptography [PDF]

open access: yes, 2014
We study quantum protocols among two distrustful parties. By adopting a rather strict definition of correctness - guaranteeing that honest players obtain their correct outcomes only - we can show that every strictly correct quantum protocol implementing ...

Cryptographic primitives in blockchains

open access: yesJournal of Network and Computer Applications, 2019
Abstract Blockchain, as one of the crypto-intensive creatures, has become a very hot topic recently. Although many surveys have recently been dedicated to the security and privacy issues of blockchains, there still lacks a systematic examination on the cryptographic primitives in blockchains.

A Novel Design of Cryptographic SP-Network Based on Gold Sequences and Chaotic Logistic Tent System

open access: yesIEEE Access, 2019
Substitution permutation network (SP-network) is a chain of linked mathematical primitives used in block cipher algorithms. The proposed novel design of cryptographic SP-network consists of three cryptographic primitives: substitution box, permutation ...

Key Assignment Scheme with Authenticated Encryption

open access: yesIACR Transactions on Symmetric Cryptology, 2018
The Key Assignment Scheme (KAS) is a well-studied cryptographic primitive used for hierarchical access control (HAC) in a multilevel organisation where the classes of people with higher privileges can access files of those with lower ones.

Towards Isogeny-Based Password-Authenticated Key Establishment

open access: yesJournal of Mathematical Cryptology, 2020
Password authenticated key establishment (PAKE) is a cryptographic primitive that allows two parties who share a low-entropy secret (a password) to securely establish cryptographic keys in the absence of public key infrastructure.

A cryptographic primitive based on hidden-order groups

open access: yesJournal of Mathematical Cryptology, 2009
Let G1 be a cyclic multiplicative group of order n. It is known that the computational Diffie–Hellman (CDH) problem is random self-reducible in G1 if φ(n) is known.

Cryptanalysis of a Pairing-free Certificateless Signcryption scheme

open access: yesICT Express, 2021
Signcryption is a very useful cryptographic primitive that aims to achieve authentication and confidentiality in an efficient manner. We cryptanalyze the signcryption scheme of Wei and Ma (2019) which is claimed to be secure.

Sound Hashing Modes of Arbitrary Functions, Permutations, and Block Ciphers

open access: yesIACR Transactions on Symmetric Cryptology, 2018
Cryptographic hashing modes come in many flavors, including Merkle-Damgård with various types of strengthening, Merkle trees, and sponge functions. As underlying primitives, these functions use arbitrary functions, permutations, or block ciphers. In this
