Postdoc @EPFL_en @EPFL 🇨🇭: Isogenies, Cryptography, and more ... @borisfouotsa.bsky.social (bluesky) @[email protected] (mastodon)
Lausanne, Switzerland
Joined November 2012
Main ingredient: orientations don't like inert primes because they (orientations) bring no advantage for computing isogenies with inert prime degree.

Quaternion signatures for isogeny group actions: showing how to adapt SQIsign and PRISM to the group actions setting, unleashing WaterSQI and PRISMO signatures that come with a tremendous speed-up over CSI-FiSh style signatures. https://t.co/piKscHIS5p

It saddens to spend time reviewing a paper, then to neither be able to see the other reviews nor take part in the discussion on that paper! Program Chairs should always enable this (and choose a reviewing platform that allows them to).

New paper with lots of my friends on computing isogeny-based hash functions using the theta model. Was fun to implement something which benchmarked at the micro rather than millisecond timescale for a change! 🍄 https://t.co/uwS5xATk5M

We provide explicit descriptions for radical 2-isogenies in dimensions one, two and three using theta coordinates. These formulas allow us to efficiently navigate in the corresponding isogeny graphs....
