CryptoExperts' Research Lab

CryptoExperts is a research group of well-recognized experts in cryptography and is connected to a network of over 60 technology partners from accross the globe. Research areas include provable security for security infrastructures and applications; the design and security evaluation of cryptographic functions, schemes and protocols; secure implementations and the physical security of embedded systems. Totaling more than 200 scientific publications and 100 invention patents, our research team, exclusively composed of industrial experts holding a PhD in cryptography, is proud to maintain a word-class expertise that simultaneously covers theoretical and practical aspects of cryptographic systems. Ranging from hardware cryptoprocessing to user-privacy, from lightweight encryption to white-box cryptography, here is a selection of our current project projects.


Ongoing Research Projects


We are already late, using cryptographic implementations in our daily life that are vulnerable to side-channel attacks. Provably secure cryptographic implementations are not practically secure and evaluations on concrete devices are not sufficient to achieve a reasonable security level. The...

A crypto-calculus platform for the Cloud.

The principle of cloud computing is to allow users to outsource computation resources to the cloud by allowing a remote service to execute, in their name, some procedures on their private data. While many commercial services are growing fast, to...

Formally proving that your crypto libs are side-channel resistant.

The PRINCE research project addresses the challenge of building leakage-resilient primitives and leakage-resilient implementations for standard algorithms. Through an appropriate security modelling, the embedded security industry has never been closer to fill in the gap between empirically secure cryptographic implementations...
