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

New trapdoor-knapsack public-key cryptosystem [PDF]
IEE Proceedings E Computers and Digital Techniques, 1985 This paper presents a new trapdoor-knapsack public-key-cryptosystem. The encryption equation is based on the general modular knapsack equation, but unlike the Merkle-Hellman scheme the knapsack components do not have to have a superincreasing structure.

Cryptographical Properties of Ising Spin Systems
, 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 ...

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

On a new fast public key cryptosystem [PDF]
, 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 : $F(x) =(a\times x)Mod(2^p)Div(2^q)$

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.Recent proposals by Mahmood et al., Braeken et al., and Chaudhry et al. aimed at establishing secure communication in AMI, asserting their methods fulfil the requisite security criteria. This paper, however, reveals that each of these proposals exhibits security vulnerabilities and lacks sufficient features for deployment.

RSA: A number of formulas to improve the search for p+qp+q
Journal of Mathematical Cryptology, 2017 Breaking RSA is one of the fundamental problems in cryptography. Due to its reliance on the difficulty of the integer factorization problem, no efficient solution has been found despite decades of extensive research. One of the possible ways to break RSA
