A Gentle Introduction to Blind signatures: From RSA to Lattice-based Cryptography
Aditya Bhardwaj, Péter Kutas
Blind signatures were first introduced by David Chaum. They allow a user to have a message signed by a signer without revealing the message itself. This property is particularly us…
SQIAsignHD: SQIsignHD Adaptor Signature
Farzin Renan, Péter Kutas
Adaptor signatures can be viewed as a generalized form of standard digital signature schemes by linking message authentication to the disclosure of a secret value. As a recent cryp…
Finding Orientations of Supersingular Elliptic Curves and Quaternion Orders
Sarah Arpin, James Clements, Pierrick Dartois +3
Orientations of supersingular elliptic curves encode the information of an endomorphism of the curve. Computing the full endomorphism ring is a known hard problem, so one might con…
Hidden Stabilizers, the Isogeny To Endomorphism Ring Problem and the Cryptanalysis of pSIDH
Mingjie Chen, Muhammad Imran, Gábor Ivanyos +3
The Isogeny to Endomorphism Ring Problem (IsERP) asks to compute the endomorphism ring of the codomain of an isogeny between supersingular curves in characteristic given only a…
Improved torsion point attacks on SIDH variants
Victoria de Quehen, Péter Kutas, Chris Leonardi +4
SIDH is a post-quantum key exchange algorithm based on the presumed difficulty of finding isogenies between supersingular elliptic curves. However, SIDH and related cryptosystems a…
An identification system based on the explicit isomorphism problem
Sándor Z. Kiss, Péter Kutas
We propose a new identification system based on algorithmic problems related to computing isomorphisms between central simple algebras. We design a statistical zero knowledge proto…
Cubes of integral vectors in dimension four
Emil W. Kiss, Péter Kutas
A system of nonzero vectors in is called an -icube if they are pairwise orthogonal and have the same length. The paper describes -icubes in …
