WebJun 20, 2024 · There are two classical NP-hard problems in lattice-based cryptography: Shortest Vector Problem (SVP): Given a lattice, to find the shortest non-zero vector in the lattice. In the graph, the vector s s is the shortest one. The SVP problem is NP-hard only under some assumptions. Closest Vector Problem (CVP). Webmap from a curve to another curve that preserves the group structure. The central objects of study in isogeny-based cryptography are isogeny graphs, i.e., graphs whose vertices represent elliptic curves, and whose edges represent isogenies between them. There is a large variety of isogeny graphs, depending on which kinds of curves and isogenies
