[Insalate Di Matematica]

Dear all,

We remind you *today*'s appointment of the series of seminars "Insalate di
Matematica". Afterwards, we invite you all for a Christmas toast.
Here are the details:

*Speaker*: *Gioella Lorenzon* (Katholieke Universiteit Leuven)

*Date and time*: *17th of December 2025, 4:45 pm (CET)*

*Title*: "Post-quantum cryptography from elliptic-curve isogenies"

*Abstract*: How do we communicate securely in a digitised world, and with
quantum computers threatening to break many of today’s cryptographic
schemes? One promising answer comes from elliptic-curve isogenies.
In this talk we will introduce post-quantum cryptography, and focus on a
branch called isogeny-based cryptography, which relies on hard problems
related to maps between elliptic curves. In particular, we will delve
into cryptographic group actions and their instantiation via (oriented)
isogenies.

*Keywords:* post-quantum cryptography, elliptic-curve isogenies, group
actions, orientations.

*Information to attend in person*
The seminar will take place at the building U9-Koinè, Università degli
Studi di Milano Bicocca; room U9-09.
