WebAs the latter, OSIDH relies on a cryptographic group action (also called e ective group action), as de ned in [10]. Namely, it means that we have a group Gacting faithfully and transitively on a set X with the following security property: if x2Xand g2G, it is computationally hard to recover gwith the knowledge of (x;gx) only1. WebThis work revisits the security of OSIDH by presenting a new attack, building upon previous work of Onuki, which has exponential complexity, but it practically breaks Colò and Kohel’s parameters unlike Onuki's attack.

WebAbstract. We present Séta, a new family of public-key encryption schemes with post-quantum security based on isogenies of supersingular elliptic curves. It is constructed from a new family of trapdoor one-way functions, where the inversion algorithm uses Petit's so called torsion attacks on SIDH to compute an isogeny between supersingular ...
