微纳复合表面HFE-7100/水的BRT现象及沸腾传热特性
微纳复合表面 沸腾传热特性 HFE-7100/水 BRT现象
2023/6/21
HFE-7100/water as a non-azeotropic and immiscible working medium can broaden the effective temperature range of nucleate boiling heat transfer. At present, it is not clear about its boiling heat trans...
Multivariate Public Key Cryptography (MPKC) has been
put forth as a possible post-quantum family of cryptographic schemes.
These schemes lack provable security in the reduction theoretic sense,
and...
Last fall degree, HFE, and Weil descent attacks on ECDLP
ECDLP Weil descent solving equations
2015/12/29
Weil descent methods have recently been applied to attack
the Hidden Field Equation (HFE) public key systems and solve the elliptic
curve discrete logarithm problem (ECDLP) in small characteristic.

MI-T-HFE, a New Multivariate Signature Scheme
post-quantum cryptography multivariate signature scheme QUARTZ
2015/12/23
In this paper, we propose a new multivariate signature scheme named
MI-T-HFE as a competitor of QUARTZ. The core map of MI-T-HFE is of an HFEv
type but more importantly has a specially designed trap...
Cryptanalysis of multi-HFE
multivariate public-key cryptosystems multi-HFE post-quantum cryptography
2015/12/18
Multi-HFE (Chen et al., 2009) is one of cryptosystems whose public key is a set of
multivariate quadratic forms over a finite field. Its quadratic forms are constructed by a set
of multivariate quad...
In this paper, we prove a closed formula for the degree of regularity of the family of HFE- (HFE Minus) multivariate public key cryptosystems over a finite field of size $q$. The degree of regularity ...
Cryptanalysis of HFE and Multi-HFE and Variants for Odd and Even Characteristic
public-key cryptography / HFE MinRank Gr鯾ner bases
2012/3/27
We investigate in this paper the security of HFE and Multi-HFE schemes as well as their minus and embedding variants. Multi-HFE is a generalization of the well-known HFE schemes. The idea is to use a ...
Prevalence of the HFE Gene Mutation in the Liver Trans-planted and Primary Hemochromatosis Patients in the Southern Iran
HFE gene Hemochromatosis Liver transplant
2015/9/22
Background: Primary hemochromatosis is an inherited disorder. Mutation in this gene is accompanied with iron overload in the body leading to organ failure that primarily affects liver. Individuals wi...
A Family of Weak Keys in HFE(and the Corresponding Practical Key-Recovery)
Cryptanalysis multivariate cryptography HFE
2009/12/29
The HFE (Hidden Field Equations) cryptosystem is one of the most interesting
public-key multivariate scheme. It has been proposed more than 10 years ago by
Patarin and seems to withstand the attacks...
Hereditary haemochromatosis is an iron-overload disease, which mainly induced by the hemochromatosis gene (HFE) mutation. Proximately 10% the whites have mutations in the HFE gene that has been identi...
基于ECC和HFE的纠错密码构造
纠错码 HFE密码 纠错密码
2009/7/21
纠错密码是一种利用纠错码体制来实现纠错和加密双重功能的一种密码体制。大部分已知的纠错密码从变换的角度看是一种对明文的线性变换。从密码分析的角度看，由于不具有非线性变换，密码的混淆能力不强，容易被攻击。利用纠错码 （Error-Correction Code，ECC） 改造基本HFE （Hidden Field Equations） 密码算法，所得的新密码算法具有纠错和加密功能，而且因其具有概率密码...
On the Security of HFE, HFEv- and Quartz
asymmetric cryptography finite fields multivariate cryptanalysis
2009/4/15
Quartz is a signature scheme based on an HFEv- trapdoor
function published at Eurocrypt 1996. In this paper we study ”inversion”
attacks for Quartz, i.e. attacks that solve the system of multivariat...

2009/4/3
In this article, we investigate the question of equivalent keys for two Multivariate Quadratic
public key schemes HFE and C*¡¡ and improve over a previously known result, to appear at

Short Signatures, Provable Security, Generic Attacks and Computational Security of Multivariate Polynomial Schemes such as HFE, Quartz and Sflash
Generic signature schemes short signatures provable security
2009/3/27
The object of this paper is the concrete security of recent
multivariate signature schemes. A major challenge is to reconcile some
”tricky” ad-hoc constructions that allow to make short signatures, ...
