Isogenies and Verifiable Delay Functions
This chapter examines the connection between isogeny-based cryptography and verifiable delay functions (VDFs), emphasizing the computational delay they introduce while ensuring security. It explains how isogenies operate within elliptic curves and their role in creating hard-to-speed-up computations, alongside a comparison of isogeny VDFs with traditional group-based VDFs. The discussion also touches on randomness generation and the practicality of signature schemes based on isogenies, highlighting both the theoretical and real-world implications.
