Introduction to Weil descent for (hyper)elliptic curves

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]. WebMay 13, 2003 · We generalize the Weil descent construction of the GHS attack to arbitrary Artin-Schreier extensions. We give a formula for the characteristic polynomial of … 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. handheld brush cutter / line trimmer
