Jérôme Govinden

I’m a Cryptography Researcher (Contractor) at TII in the Protocols Team. My research centers around symmetric-key cryptography, particularly on the eﬃcient design, analysis, and implementation of provably secure schemes with real-world applications.

I obtained my PhD in Computer Science from TU Darmstadt in 2025, under the supervision of Jean Paul Degabriele. 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).
