CSIDH: an efficient Post-Quantum Commutative Group Action
TL;DR: The Diffie–Hellman scheme resulting from the group action allows for public-key validation at very little cost, runs reasonably fast in practice, and has public keys of only 64 bytes at a conjectured AES-128 security level, matching NIST’s post-quantum security category I.
Journal Article
An efficient key recovery attack on SIDH (preliminary version)
TL;DR: This work presents an efficient key recovery attack on the Supersingular Isogeny Diffie–Hellman protocol (SIDH), based on a “glue-and-split” theorem due to Kani, which breaks the instantiation SIKEp434 in about one hour on a single core.
Journal ArticleDOI
New equidistribution estimates of Zhang type

TL;DR: For arithmetic progressions to large smooth squarefree moduli, with respect to congruence classes obeying Chinese remainder theorem conditions, the authors obtained an exponent of distribution 1/2 + 7/300.
Journal ArticleDOI
Computing zeta functions of nondegenerate curves
TL;DR: A p-adic algorithm to compute the zeta function of a nondegenerate curve over a finite field using Monsky-Washnitzer cohomology, which works for almost all curves with given Newton polytope.
Journal ArticleDOI
Moving Out the Edges of a Lattice Polygon
TL;DR: The dual operations of taking the interior hull and moving out the edges of a two-dimensional lattice polygon are reviewed and it is shown how the latter operation naturally gives rise to an algorithm for enumerating lattice polygons by their genus.
