In this short note we try to find radical isogenies on twisted Edwards curves. We will do so by first looking at what radical isogenies are, and then look at how radical isogenies should work on twisted Edwards curves. Finally, by firing up a computer algebra system, we find the concrete radical isogeny formula forContinue reading “Radical isogenies on (twisted) Edwards curves”

Deepfakes and digital signatures
Our concept of trust is about to change. The recent rise of deepfakes, highly convincing fake audio or video files that are manipulated using machine learning techniques, is deeply disturbing and will have a high impact on what is meant by trust in the near future. How do we decide what is real and what is fake? WillContinue reading “Deepfakes and digital signatures”
