Poly-Dragon: An efficient Multivariate Public Key Cryptosystem [PDF]

open access: yes, 2009
In this paper we propose an efficient multivariate public key cryptosystem. Public key of our cryptosystem contains polynomials of total degree three in plaintext and ciphertext variables, two in plaintext variables and one in ciphertext variables ...

On Oleshchuk’s Public Key Cryptosystem

open access: yes, 2004
This paper revisits a public key cryptosystem which is based on finite Church-Rosser string-rewriting systems. We consider some ideas for cryptanalysis and discuss issues concerning practical usage.

Security of the cryptosystems based on ergodic matrices

open access: yesTongxin xuebao, 2015
The security of the public-key cryptosystems based on ergodicmatrices over finite field was analysed.According to the public key,a system of linear equations for the forged secret key bits is obtained by inverse matrix elimination method.It is proved ...

Research on McEliece and Niederreiter Public-key Cryptosystem Algorithm Based on Quantum BCH Codes

open access: yes工程科学与技术, 2018
In order to resist the security threat of quantum computing attacks to the traditional cryptosystem, a class of McEliece public-keycryptosystems was designed in this paper, based on the fact that no quantum computing algorithm can attack the McEliece ...

A Quantum Public-Key Cryptosystem with Reusable Keys Using Entangled States

open access: yesApplied Sciences
In most traditional quantum public-key cryptosystems, the public key held by the key management center (KMC) is a group of quantum systems. The public key is destroyed after a secret communication process, and so users must reconstruct the public key ...

Cryptanalysis of the Cai-Cusick Lattice-based Public-key Cryptosystem [PDF]

open access: yes, 2008
In 1998, Cai and Cusick proposed a lattice-based public-key cryptosystem based on the similar ideas of the Ajtai-Dwork cryptosystem, but with much less data expansion. However, they didn\u27t give any security proof. In our paper, we present an efficient

A random number generator based on NTRU cryptosystem [PDF]

open access: yesMaejo International Journal of Science and Technology, 2010
A random number generator based on the operation of the NTRU cryptosystem is proposed. By using the proposed generator together with the NTRU cryptosystem, we can save hardware and software components.
