Webfor post-quantum cryptography: besides making OSIDH prohibitively expensive, it makes it at best as secure as lattice based schemes, without the e ciency, the versatility and … WebIn a sense, OSIDH uses class groups which are more structured than in CSIDH, creating a potential weakness that was already recognized by Colò and Kohel. To circumvent the weakness, they proposed an ingenious way to realize a key exchange by exchanging partial information on how the class group acts in the neighborhood of the public curves, and …

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 ... dystopian realityWeb4 de mar. de 2024 · Security: Directed by Alain Desrochers.
