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

A tiny public key scheme based on Niederreiter Cryptosystem
, 2023 Due to the weakness of public key cryptosystems encounter of quantum computers, the need to provide a solution was emerged. The McEliece cryptosystem and its security equivalent, the Niederreiter cryptosystem, which are based on Goppa codes, are one of ...

On Oleshchuk\u27s Public Key Cryptosystem
, 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.

Improvement on the XTP public key cryptosystem and communication protocol of provable security
Tongxin xuebao, 2007 A new trace function was proposed,the XTP public key cryptosystem based on the 3-rd order LFSR se-quence（the so-called XTR3 system） was extended to the XTR4 system based on the 4-th order LFSR sequence.XTR4 key was shorter in length than that of the XTR3

Cryptanalysis of a divisor class group based Public-Key Cryptosystem
, 2014 We prove that the public-key cryptosystem proposed by H. Kim and S. Moon, in "New Public-Key Cryptosystem Using Divisor Class Groups", ACISP 2001 [1] is not secure by solving discrete logarithm problem for the divisor class groups used in the proposal ...

The Mathematics of the NTRU Public Key Cryptosystem
, 2015 International audienceThe NTRU cryptosystem is a fast public key cryptosystem presented in 1996 by Hoffstein, Pipher and Silverman. It is resistant to quantum attacks and is categorized as a post quantum cryptosystem.

Strongly Secure Certificate-based Blind Signature Scheme Without Pairings
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.
