About Gustavo Banegas

Currently, I am senior cryptographer working at Qualcomm France in Sophia Antipolis, France.

Previously, I was a Post-Doc working with Benjamin Smith at the GRACE Team at INRIA in France.

From November of 2019 until November of 2020, I was a Post-Doc Researcher at the Department of Computer Science and Engineering at Chalmers University of Technology in Sweden.

In the middle of November of 2019, I finished my PhD at the Eindhoven University of Technology under the supervision of Tanja Lange and Daniel J. Bernstein. In my PhD, I was a fellow of ECRYPT-NET, an EU-financed project within the “Horizon 2020” program, thanks to one of the Marie Skłodowska-Curie actions. You can find my PhD Thesis: “Selected constructive and destructive approaches to post-quantum cryptography” in this link.

In the beginning of October (2015), I defended my master thesis under the supervision of Ricardo Custódio and Daniel Panario.

In 2012, I finished my diplom in computer science at UFSC (Federal University of Santa Catarina) under the supervision of Ricardo Custódio.

Selected Publications





Jul 2022 – Present Sophia Antipolis
Develop secure solutions in cryptography to Qualcomm Snapdragon. The main point is to put Post-Quantum Cryptography (PQC) into embedded devices.



Dec 2020 – Jul 2022 Paris
In this PostDoc, the focus is to implement post-quantum cryptography into embedded devices. More precisely, implement post-quantum schemes (isogeny-based, lattice-based, and hash-based) into RIOT-OS.


Chalmers University of Technology

Nov 2019 – Nov 2020 Gothenburg
As a postdoc researcher I will continue researching about cryptography with focus in post-quantum cryptography and its applications. I will be part of the WASP Expedition project which is a multidisciplinary project for innovative approaches in technology.
