ePrint Report: DEFEND: Verifiable Delay Functions from Endomorphism Rings

Knud Ahrens, Jens Zumbrägel

We present a verifiable delay function based on isogenies of supersingular elliptic curves, using Deuring correspondence and computation of endomorphism rings for the delay. For each input x a verifiable delay function has a unique output y and takes a predefined time to evaluate, even with parallel computing. Additionally, it generates a proof by which the output can efficiently be verified. In our approach the input is …
