Improved Subfield Curve Search For Specific Field Characteristics
Abstract
Isogeny-based cryptography relies its security on the hardness of the supersingular isogeny problem: finding an isogeny between two supersingular curves defined over a quadratic field.
The Delfs-Galbraith algorithm is the most efficient procedure for solving the supersingular isogeny problem with a time complexity of
