Title:
Generalising Fault Attacks to Genus Two Isogeny Cryptosystems
Authors: Ariana Goh, Chu-Wee Lim, Yan Bo Ti
Abstract:In this paper we generalise Ti’s fault attack and the loop abort fault attacks on supersingular isogeny cryptosystems (genus one) to genus two. Genus two isogeny based cryptosystems are generalisations of its genus one counterpart, as such, attacks on the the latter are believed to generalise to the former. Fault attacks on supersingular elliptic curve isogeny cryptography has been shown to be practical. We show in this paper that fault attacks continue to be practical in genus two, albeit with a few additional traces required.
