Experimental cheat-sensitive quantum weak coin flipping

Nature Communications, 2023
Quantum-enhanced versions of weak coin flipping (a cryptographic primitive where two mistrustful parties agree on a random bit while favouring opposite outcomes) have been proposed in the past but never realised.

Enhanced Matrix Power Function for Cryptographic Primitive Construction

Symmetry, 2018
A new enhanced matrix power function (MPF) is presented for the construction of cryptographic primitives. According to the definition in previously published papers, an MPF is an action of two matrices powering some base matrix on the left and right. The

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

Groups, 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.

Key Assignment Scheme with Authenticated Encryption

IACR 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.
