Title:
A note on the cost of computing odd degree isogenies
Authors: Daniel Cervantes-Vázquez, Francisco Rodríguez-Henríquez
Abstract:Finding an isogenous supersingular elliptic curve of a prescribed odd degree is an important building block for all the isogeny-based protocols proposed to date. In this note we present several strategies for the efficient construction of odd degree isogenies, which outperform previously reported methods when dealing with isogeny degrees in the range [7, 2^{20}].
