About the research centre or Inria department

The Inria Rennes - Bretagne Atlantique Centre is one of Inria's eight centres and has more than thirty research teams. The Inria Center is a major and recognized player in the field of digital sciences. It is at the heart of a rich R&D and innovation ecosystem: highly innovative PMEs, large industrial groups, competitiveness clusters, research and higher education players, laboratories of excellence, technological research institute, etc.


The selected applicant will work within the WIDE research team at Inria of the University of Rennes (https: // WIDE focuses on large- scale distributed systems and applications, as well as on privacy, and distributed machine learning.

This engineering position is funded by the SOTERIA H2020 project (https: // www. which aims to develop a user-centric, citizen-driven tool to help European citizens to manage their personal data. The project therefore involves close collaboration with French international partners such as AriadNext by IDNow, Idiap Switzerland, COSIC Team @ KU Leuven, a complete list is available at https: // www.

The successful applicant will have the opportunity to travel and collaborate with such international partners. All travel expenses will be covered by Inria.


The recruited engineer is expected to contribute to the implementation of a distributed data vault that can (i) store personal data while keeping it safe from third parties, (ii) support computation on encrypted or otherwise protected personal data to obtain aggregate statistics while respecting the privacy of the individual data items, (iii) provide means to remunerate users that enable computation on their personal data.

More specifically, the engineer will intially work on key management and distribution protocols. In particular, they will work on use of trusted execution environments like Intel SGX, ARM TrustZone and IOS's Secure Enclave, to store and process private information in the key-management process.

Later on they will contribute to the implementation of privacy-preserving machine-learning algorithms using TEEs, multiparty computation and other cryptographic techniques.

The engineer will work in close contact with the researchers involved in the project, both at Inria, and at KU Leuven. They will also have frequent interaction with other project partners across Europe.
