Security of the cryptosystems based on ergodic matrices
Tongxin 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
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
Applied SciencesIn 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]
, 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

The Use of Fractions in Public-Key Cryptosystems [PDF]
, 2007 This paper discusses an asymmetric cryptosystem based on fractions, the Rk-system, which can be implemented fast using only additions and multiplications. Also it is very simple to initialize the system and to generate new keys. The Rk-system makes use of the difficulty to compute the numerator and the denumerator of a fraction only knowing the rounded

A random number generator based on NTRU cryptosystem [PDF]
Maejo 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.

An Efficient Public Key Encryption Scheme Based on QC-MDPC Lattices
IEEE Access, 2017 In this paper, we introduce a new family of lattices, namely QC-MDPC lattices, which are a special case of LDPC lattices, and an improved bit flipping algorithm for decoding of these lattices. Encoding and decoding implementations of QC-MDPC lattices are

Computation of private key for LUC cryptosystem [PDF]
, 2009 LUC cryptosystem is a public key cryptosystem based on Lucas functions. The encryption of this cryptosystem is relatively easy since we have the knowledge of public key e, two primes p and q and also the message M.
