INRIA Cryptography Group is a research team operating within the French national research institute INRIA focused on cryptographic theory and practice. The group has contributed to public-key cryptography, symmetric cryptography, cryptanalysis, and applied cryptographic protocols, interacting with academic institutions such as École normale supérieure, Université Paris-Saclay, Sorbonne Université, and industrial partners including Thales Group, Airbus, and Gemalto. Its work connects to international standards bodies and conferences like IETF, NIST, RSA Conference, CRYPTO, and EU-funded Horizon 2020 initiatives.

History

The group's origins trace to early collaborations between researchers at INRIA, CNRS, and Université de Grenoble during the 1980s and 1990s, influenced by foundational results from figures associated with Diffie–Hellman key exchange, RSA (cryptosystem), and early work at Bell Labs. During the 2000s the team expanded through projects with CEA, École Polytechnique, and Collège de France, responding to cryptographic challenges posed by deployments in entities such as European Commission projects and national efforts like those of ANSSI. The mid-2010s brought collaborations with initiatives around post-quantum standards led by NIST and research networks including ECRYPT and Horizon Europe consortia.

Research Areas

The group's research spans theoretical and applied topics: post-quantum cryptography linked to lattices and isogenies studied alongside work from Mathematics Research Center collaborators and parallels to researchers at IBM Research and Google Research; symmetric-key design and analysis with relevance to ciphers evaluated at CRYPTO and Eurocrypt; zero-knowledge protocols connected to advances by teams at University of California, Berkeley and Massachusetts Institute of Technology; formal verification and provable security related to frameworks from Leiden University and ETH Zurich. Other areas include secure multiparty computation intersecting with projects at Microsoft Research and Zcash Company, homomorphic encryption with links to Microsoft Research and IBM Research, and side-channel analysis reflecting work at NXP Semiconductors and STMicroelectronics.

Projects and Collaborations

Notable collaborative projects have included EU-funded consortia involving INRIA, CNRS, Imperial College London, and KU Leuven; joint work with industry partners such as Orange S.A., Dassault Systèmes, and Capgemini; and participation in standardization efforts with ETSI, IETF, and NIST panels. The group has contributed to cross-disciplinary initiatives with CEA-Leti, CEA, and medical technology teams at INSERM for secure health-data protocols, and has engaged with blockchain and distributed ledger projects alongside Ethereum Foundation and Hyperledger contributors.

Notable Members and Alumni

Researchers and alumni have held positions at institutions like École normale supérieure, Université Paris-Saclay, Princeton University, Stanford University, ETH Zurich, University of Cambridge, University College London, Columbia University, Cornell University, and Max Planck Institute for Security and Privacy. Many alumni moved to industry roles at Google, Facebook (Meta), Amazon Web Services, IBM, Microsoft, Thales Group, and startups spun out to form companies similar to Cryptography Research, Inc. and Zama. The group’s personnel have served on program committees for CRYPTO, EUROCRYPT, ASIACRYPT, CHES, and editorial boards of journals like Journal of Cryptology and IEEE Transactions on Information Theory.

Publications and Software Contributions

The team has published in venues including CRYPTO, EUROCRYPT, ASIACRYPT, CHES, PKC, TCC, and journals such as Journal of Cryptology, IEEE Transactions on Information Theory, ACM Transactions on Information and System Security, and Mathematics of Computation. Software contributions include implementations and libraries used in evaluations at NIST competitions and by projects like OpenSSL-adjacent toolchains, reference implementations for post-quantum candidates evaluated alongside submissions from groups at Duke University and NTRU. The group has released tooling for formal verification with influences from projects at INRIA Saclay, UPenn, and University of Oxford.

Awards and Impact

Group members have received recognitions from organizations and awards such as fellowships at École Polytechnique, grants from European Research Council, distinctions connected to CNRS Silver Medal, and invitations to speak at major venues including IETF, RSA Conference, and Black Hat USA. Their cryptanalytic results have impacted standardization processes at NIST and policy discussions within European Commission cybersecurity programs, and have informed security engineering at firms like Airbus and Thales Group.

Facilities and Organization

The group operates across INRIA research centers including locations affiliated with INRIA Saclay, INRIA Grenoble Rhône-Alpes, and INRIA Paris. It is structured with principal investigators, postdoctoral researchers, PhD students funded via grants from Agence Nationale de la Recherche and European Research Council, and technical staff collaborating with laboratories of CNRS, École normale supérieure, and Université Paris-Saclay.
