A Smart Approach for GPT Cryptosystem Based on Rank Codes

open access: yes, 2010
The concept of Public- key cryptosystem was innovated by McEliece's cryptosystem. The public key cryptosystem based on rank codes was presented in 1991 by Gabidulin -Paramonov-Trejtakov(GPT).

Cryptographical Properties of Ising Spin Systems

open access: yes, 2000
The relation between Ising spin systems and public-key cryptography is investigated using methods of statistical physics. The insight gained from the analysis is used for devising a matrix-based cryptosystem whereby the ciphertext comprises products of ...

On a new fast public key cryptosystem [PDF]

open access: yes, 2015
This paper presents a new fast public key cryptosystem namely : a key exchange algorithm, a public key encryption algorithm and a digital signature algorithm, based on the difficulty to invert the following function : $F(x) =(a\times x)Mod(2^p)Div(2^q)$

Applications of single-qubit rotations in quantum public-key cryptography

open access: yes, 2008
We discuss cryptographic applications of single-qubit rotations from the perspective of trapdoor one-way functions and public-key encryption. In particular, we present an asymmetric cryptosystem whose security relies on fundamental principles of quantum ...

Cryptanalysis of a homomorphic public-key cryptosystem over a finite group

open access: yesJournal of Mathematical Cryptology, 2007
The paper cryptanalyses a public-key cryptosystem recently proposed by Grigoriev and Ponomarenko, which encrypts an element from a fixed finite group defined in terms of generators and relations to produce a ciphertext from .

Improving the efficiency of the LDPC code-based McEliece cryptosystem through irregular codes

open access: yes, 2013
We consider the framework of the McEliece cryptosystem based on LDPC codes, which is a promising post-quantum alternative to classical public key cryptosystems.

Hyperchaos‐Driven 3D RGB Image Scrambling and Encryption for Multi‐Image Security

open access: yesIET Image Processing, Volume 20, Issue 1, January/December 2026.
The proposed encryption scheme scrambles N colour images by stacking them into a three‐dimensional red, green, blue image, generating a secure 256‐bit key using SHA‐256 and a user‐provided salt, and applying a five‐dimensional multi‐wing hyperchaotic system to produce random key streams.
