Jérôme Govinden
I’m a final‑year PhD candidate at TU Darmstadt (Germany), under the supervision of Jean Paul Degabriele. My research centers around symmetric-key cryptography, particularly on the efficient design, analysis, and implementation of provably secure schemes with real-world applications.
In Fall 2024, I visited the Cryptography Group at the University of Washington, hosted by Stefano Tessaro. Previously, I was a research intern in the Cryptography Research Center of TII (UAE) and in the LIP6 Computer Science Laboratory (France). I hold a Master degree in Mathematics (Paris Cité University) and Computer Science (Sorbonne University).

Latest News
(Oct. 2025) I have submitted my PhD thesis on Improving the Security and Efficiency of Symmetric Primitives in Cryptography, which I will defend in December. I will also start a new position as a Cryptography Researcher (Contractor) at TII.
(Jul. 2025) Jean Paul Degabriele presented our proposal (with Jan Gilcher and Kenneth G. Paterson) for an Improved ChaCha-based AEAD Scheme as a work item of the CFRG at the IETF 123 meeting.
(May 2025) Our paper Succinct PPRFs via Memory-Tight Reductions (with Joël Alwen, Chris Brzuska, Patrick Harasser, and Stefano Tessaro) was accepted to CRYPTO 2025.
