WebIn this paper we extend the Weil descent attack due to Gaudry, Hess and Smart (GHS) to a much larger class of elliptic curves. This extended attack applies to fields of composite degree over F2. The principle behind the extended attack is to use isogenies to find an elliptic curve for which the GHS attack is effective.

WebThe GHS attack yields only degree 2 minimal elliptic subcovers of hyperelliptic curves of genus 3. In this paper, we study the properties of elliptic subcovers of genus 3 hyperelliptic curves. Using these properties, we find some minimal elliptic subcovers of degree 4, which can not be constructed by GHS attack. Keywords Elliptic Subcover Webare known for special classes of elliptic curves, including those for which the multiplicative order of q modulo d is small [7, 16], and for prime-ﬁeld anomalous curves [20, 21, 23].

WebIn this paper, we analyze the Gaudry-Hess-Smart (GHS) Weil descent attack on the elliptic curve discrete logarithm problem (ECDLP) for elliptic curves defined over characteristic two finite fields of composite extension degree. 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].
