I am a cryptographer working within CryptoExperts, a solution provider in the area of cryptography.
Before joining CryptoExperts in 2010, I have been a cryptography engineer at Oberthur Technologies (smart card manufacturer, now Idemia) and PhD student at University of Luxembourg (2006-2009) focusing on cryptographic implementations and side-channel attacks.
This webpage contains information about my scientific activities, publications, PhD thesis, and talks.
Current projects:
- Pyjamask: a cipher submitted to NIST call for lightweight cryptography
- VERISICC: FUI funded project on formal verification of side-channel countermeasures
