A New Public Key Cryptosystem Based on Edwards Curves
Elliptic curves Twisted Edwards curves RSA cryptosystem
2019/9/19
The elliptic curve cryptography plays a central role in various cryptographic schemes and protocols. For efficiency reasons, Edwards curves and twisted Edwards curves have been introduced. In this pap...
Two-Face: New Public Key Multivariate Schemes
Multivariate Cryptography HFE Generalization new multivariate quadratic permutations
2017/12/19
We present here new multivariate schemes that can be seen as HFE generalization having a property called `Two-Face'. Particularly, we present five such families of algorithms named `Dob', `Simple Pat'...
A New Public-Key Cryptosystem via Mersenne Numbers
public-key cryptosystem Public-Key Cryptosystem via Mersenne Numbers
2017/5/31
In this work, we propose a new public-key cryptosystem whose security is based on the computational intractability of the following problem: Given a Mersenne number p = 2^n - 1, where n is a prime, a ...
A new public key system based on Polynomials over finite fields GF(2)
discrete logarithm problem public-key cryptography digital signatures
2016/1/8
In this paper a new public key system based on polynomials over fields GF(2) is developed.
The security of the system is based on the difficulty of finding discrete logarithms over GF(2k
)
with suf...
Attack on A New Public Key Cryptosystem from ISC'02
Public key cryptography Attack, Polynomial Matrix
2009/4/15
In ISC 2002, J. Zheng [8] proposed a new public key cryp-
tosystem whose security is based upon the algebraic problem of reducing
a high degree matrix to its canonical form by similarity transformat...
New Public Key Authentication Frameworks with Lite Certification Authority
Public Key Authentication Frameworks Lite Certification Authority
2008/11/19
Two variants of CA-based public key authentication frame-
work are proposed in this paper. The one is termed as public key cryp-
tosystem without certificate management center (PKCwCMC) and the
oth...
New Public Key Cryptosystems Using Polynomials over Non-commutative Rings
Public Key Cryptosystems Polynomials Non-commutative Rings
2008/9/22
In this paper, we propose a new method for designing public
key cryptosystems based on general non-commutative rings. The key idea
of our proposal is that for a given non-commutative ring, we can de...
