Ghs attack elliptic thesis
Webthat the GHS attack does not apply to most deployed systems. However, there are a few deployed elliptic curve systems which use the fields F 2155 and F 2185 [18]. Hence … WebA main approach for analysis of the GHS attack until now is to investi-gate the genus g(C) of the covering curve Cas a function of the extension degree dof the definition field kd of C0.The genus g(C) of Cwas calcu- lated on definition finite fields of characteristic 2 for elliptic curves C0 using Artin-Schreier theory in [13] and generalized to arbitrary Artin …

Webto an isogenous elliptic curve vulnerable to the GHS method [6], and Hess generalized the GHS Weil descent attack from hyperelliptic H/Fq to possibly non-hyperelliptic C/Fq [7, 8]. … WebA relatively new attack called GHS attack, which is based on the idea of Weil descent suggested by Frey[5], was proposed by Gaudry, Hess, and Smart in 2000 [6]. The GHS attack transfer the discrete logarithm problem (DLP) in the group of rational points of an elliptic curve E over an extension kd of a finite field k to the DLP in the Jacobian
WebMeanwhile, a much more powerful attack is known as the GHS attack which makes use of certain internal structure of elliptic and hyperelliptic curves defined over extension fields. Weil descent was firstly introduced by Frey[13] to elliptic curve cryptosystems. The idea was developed to the GHS attack by Gaudry, Hess, Smart[19]. Webincreased the number of elliptic curves which succumb to the GHS attack for certain parameters. The GHS attack has also been generalised to hyperelliptic curves, in even characteristicby Galbraith [10] and odd characteristicby Diem [7]. Th´eriault[26] considers a special class of Artin-Schreier curves in any characteristic. In this paper we ...
WebFeb 1, 2010 · As an application, the number of elliptic curves that succumb to the basic GHS attack is considerably increased, thereby further weakening curves over GF 2 155. … WebThe major difficulty of cover attacks lies in constructing the curveC. A solution was first proposed by Gaudry, Hess and Smart [7] for elliptic curves over binary fields and further generalized by Diem [3] to odd characteristic. Both are now referred to as GHS attack. The construction is achieved by techniques from the theory of function ...
