On the security of the KMOV public key cryptosystem [PDF]

open access: yes, 1997
This paper analyzes the KMOV public key cryptosystem, which is an elliptic curve based analogue to RSA. It was believed that this cryptosystem is more secure against attacks without factoring such as the Hastad-attack in broadcast application. Some new attacks on KMOV are presented in this paper that show the converse.

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.

A Comment on Niederreiter’s Public Key Cryptosystem [PDF]

open access: yes, 2007
In this comment we show that a recently proposed public key cryptosystem is not safe for most of the practical cases. Furthermore, it is shown that the security of this system is closely connected with the problem of computing logarithms over a finite field.

Private Key Extension of Polly Cracker Cryptosystems [PDF]

open access: yesComputer Science Journal of Moldova, 2008
In 1993 Koblitz and Fellows proposed a public key cryptosystem, Polly Cracker, based on the problem of solving multivariate systems of polynomial equations, which was soon generalized to a Dröbner basis formulation.

Analysis of the MQQ Public Key Cryptosystem

open access: yes, 2010
MQQ is a multivariate cryptosystem based on multivariate quadratic quasigroups and the Dobbertin transformation [18]. The cryptosystem was broken both by Gröbner bases computation and MutantXL[27]. The complexity of Gröbner bases computation is exponential in the degree of regularity, which is the maximum degree of polynomials occurring during the ...

Further research on public-key cryptosystems based on third-order recurrence sequence

open access: yesTongxin xuebao, 2005
Properties of third-order recurrence sequences were investtgated and a new variant of GH public-key cryptosystem was proposed. It is further improved to be a probabilistic public-key cryptosystem.

On a new fast public key cryptosystem

open access: yesCoRR, 2014
This paper presents a new fast public key cryptosystem namel : a key exchange algorithm, a public key encryption algorithm and a digital signature algorithm, based on the difficulty to invert the following function: $$F(x) =(a\times x)Mod(2^p)Div(2^q).$$ Mod is modulo operation , Div is integer division operation , a , p and q are integers where $( p ...

Strongly Secure Certificate-based Blind Signature Scheme Without Pairings

open access: yes工程科学与技术, 2013
:Certificate-based Cryptosystem is the latest evolution of traditional public key cryptosystem, but most of existing certificate-based signature schemes were constructed by pairings, which led to low calculation efficiency.
