I’m a cryptographer in the Security team (the “Donjon”) at Ledger, the leading manufacturer of hardware wallets. Previously, I have worked in the cryptography lab at ANSSI and at Orange Labs. I hold a Ph.D. in Computer Science from the University of Versailles Saint-Quentin-en-Yvelines supervised by Jacques Patarin and Henri Gilbert.
I have co-designed the block cipher PRESENT (an ISO standard), the authenticated encryption scheme Deoxys (included in the final portfolio of the CAESAR competition), and the MuSig2 multisignature scheme (Bitcoin Improvement Proposal BIP 327).
I’ve been a member of IACR since 2007.
