What CryptoExperts does

CryptoExperts SAS is a Paris-based cryptography research and consulting firm founded in February 2009 by internationally recognized industrial and academic researchers in IT security and cryptography. The company operates with a small team (1-10 employees) composed exclusively of PhD-level cryptography experts, co-founded by Pascal Paillier and Louis Goubin, with Matthieu Rivain serving as CEO. Its mission is to bridge the gap between the scientific state-of-the-art in cryptography and the technology level found in commercial security products, offering both consulting services and business-driven innovation.

The firm's offering is organized around four technology practice areas (Cryptographic Libraries, Homomorphic Encryption, Post-Quantum Cryptography, and White-Box Cryptography) and five consulting service lines (Design, Implementation, Evaluation, Certification, and Training). Revenue is generated primarily through professional services engagements and licensing/royalties from innovation partnerships, with pricing undisclosed. CryptoExperts holds 100+ invention patents and has produced 200+ scientific publications, and co-founder Pascal Paillier serves as main editor of ISO/IEC 18033-6 (Homomorphic Encryption) and ISO/IEC 27551 (Attribute-based Entity Authentication).

The customer base consists of leading technology companies, government agencies, and academic institutions across defense, aerospace, telecommunications, semiconductors, identity, media security, and blockchain verticals. Named clients and partners include ANSSI, Thales Communications SA, Airbus, CEA List, Orange Labs, StarkWare, Idemia, Secure-IC, Viaccess-Orca, Inria, ENS, CNRS, Sorbonne Université, and University of Luxembourg. The firm participates in multiple French-funded collaborative research projects (RISQ, VERISICC, CRYPTOCOMP, SWITECH, KISS) and markets primarily through academic publications, conference presentations, and standardization participation rather than traditional sales channels.

Core offering

CryptoExperts provides expert cryptography consulting services spanning design, implementation, evaluation, certification, and training, organized around four technology practice areas: cryptographic libraries, homomorphic encryption, post-quantum cryptography, and white-box cryptography. The firm delivers highly-optimized cryptographic software and hardware implementations, security-by-design consulting, formal evaluation against common pitfalls, and support for security certifications for enterprise and government clients.

Product overview

CryptoExperts is a cryptography research and consulting company offering professional services rather than a traditional product suite. Their offering consists of four specialized technology practice areas (Cryptographic Libraries, Homomorphic Encryption, Post-Quantum Cryptography, and White-Box Cryptography) combined with five consulting service lines (Design, Implementation, Evaluation, Certification, and Training). The company operates a research laboratory contributing to international standardization (particularly ISO standards for Homomorphic Encryption and Attribute-based Entity Authentication) and maintains an extensive portfolio of collaborative research projects addressing side-channel security, formal verification, post-quantum migration, and secure implementations.

Products and services

• Cryptographic Libraries Cycle-accurate optimized cryptographic libraries developed and delivered for various hardware and software platforms, supporting standard and advanced cryptographic algorithms, drawing on more than 20 years of experience. Targeted at technology companies that need production-grade cryptographic primitives.
• Homomorphic Encryption Advanced cryptographic technology enabling processing of sensitive information while it remains encrypted, supporting privacy-preserving secure cloud computing. Targeted at organizations that need to compute on encrypted data without exposing plaintext.
• Post-Quantum Cryptography Secure cryptographic alternatives to RSA and Elliptic Curve cryptography designed to remain safe when quantum computers become capable of breaking current public-key schemes. Targeted at organizations preparing their security products for the post-quantum transition.
• White-Box Cryptography Transformation of keyed cryptographic algorithms into unintelligible programs that preserve the original functionality, enabling secure execution in untrusted environments without exposing underlying keys. Targeted at vendors deploying cryptography in hostile client-side or embedded environments.
• Design Services Security-by-design consulting to help clients build innovative products that require standard or advanced cryptographic tools such as elliptic curves, identity-based encryption, post-quantum signatures, and e-cash. Targeted at product teams designing new cryptography-dependent security products.
• Implementation Services Development and delivery of highly-optimized cryptographic software implementations on various software and hardware platforms, supporting standard and advanced cryptographic algorithms. Targeted at engineering teams that need high-assurance, platform-specific cryptographic code.
• Evaluation Services External expert review and security analysis of cryptographic designs at any development stage to help clients avoid common and uncommon pitfalls. Targeted at organizations seeking independent cryptographic assessment of in-progress or deployed designs.
• Certification Services Assistance in achieving security certifications through in-depth design and security analysis to identify cryptographic misconceptions and propose appropriate alternatives. Targeted at vendors preparing products for formal security certification (e.g., common criteria, ANSSI qualification).
• Training Services Professional training programs in cryptography covering cryptographic design, implementation, and security evaluation. Targeted at security engineers, developers, and researchers who need to deepen their practical and theoretical cryptography skills.
