Description
n 2001 K. Kedlaya suggested an algorithm to compute the zeta function of a hyperelliptic curve over a finite field of small odd characteristic. The basic idea of his approach is to compute the explicit Frobenius action on the Monsky-Washniter cohomology in dimension one. Later his method was extended by P. Gaudry and N. Guerel to superelliptic curve and by J. Denef and F. Vercauteren to hyperelliptic curves in even characteristic.

MIKE: An efficient and compact NIKE Based on a Commutative Monoidal Action
Orateur : Jonathan Komada Eriksen - COSIC, KU Leuven
Robert recently described a powerful correspondence between certain (Hermitian) modules and (polarized) abelian varieties, which simultaneously generalizes both the class-group action underlying protocols such as CSIDH, and the Deuring correspondence, underlying protocols such as SQIsign. Using this correspondence, he also proposed how to construct a post-quantum NIKE, called MIKE, which, at a[…]-
