WebLondon Mathematical Society ISSN 1461–1570 GENERALISING THE GHSATTACK ON THE ELLIPTIC CURVE DISCRETE LOGARITHM PROBLEM F. HESS Abstract ... Webthe Weil descent attacks are almost never computationally efficient and are slower than other known algorithms for the ECDLP. The remainder of this paper is organized as follows. The GHS attack and its general-ization by Hess are outlined in Section 2. The asymptotic effectiveness of the generalized GHS (gGHS) attack is examined in Section 3.

The GHS attack has been then extended and analyzed by many authors [3][10][16][17][18][24][25][26][35][36] and conceptually generalized to the cover attack by Frey and Diem[6]. The GHS attack, in terms of the cover attack, can be described as to map the snow in buffalo this weekend https://livingwelllifecoaching.com

WebAbstractIn this paper, the authors 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. For each such field F2N, where N is in [100,600], elliptic curve parameters are identified such that ...
