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]. 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. 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].
