über das Thema:
As you read this text, your browser is tirelessly performing computations on an elliptic curve (the more third party trackers, the more computations, yay!). For 20 years now, elliptic curves have been the mainstay of public key cryptography, but the world is changing. As research on quantum computers slowly progresses, we are in desperate need of new forms of cryptography which, unlike elliptic curves, are not attacked by quantum algorithms.
Enter isogenies of elliptic curves (and higher dimensional abelian varieties). First proposed as a foundation for cryptography at the turn of the century, they have in recent times attracted a considerable amount of interest, thanks to their versatility, efficiency and, of course, quantum-resistance. In an interesting twist of events, possibly the most famous isogeny-based scheme, SIKE, fell victim to a devastating *classical* attack in the summer of 2022. Nevertheless the field of isogeny-based cryptography continues to expand, as the influx of researchers keeps growing.
In this talk I will introduce the may concepts of isogeny-based cryptography, and survey the most active topics currently researched.
