Title:
Towards a Quantum-resistant Weak Verifiable Delay Function
Authors: Thomas Decru, Luciano Maino, Antonio Sanso
Abstract:In this paper, we present a new quantum-resistant weak Verifiable Delay Function based on a purely algebraic construction. Its delay depends on computing a large-degree isogeny between elliptic curves, whereas its verification relies on the computation of isogenies between products of two elliptic curves. One of its major advantages is its expected fast verification time. However, it is important to note that the practical implementation of our theoretical framework poses significant challenges. We examine the strengths and weaknesses of our construction, analyze its security and provide a proof-of-concept implementation.
