Verifiable Delay Functions from Supersingular Isogenies and Pairings

Luca De Feo and Simon Masson and Christophe Petit and Antonio Sanso

Abstract: We present two new Verifiable Delay Functions (VDF) based on assumptions from elliptic curve cryptography. We discuss both the advantages and some drawbacks of our constructions, we study their security and we demonstrate their practicality with a proof-of-concept implementation.
