Security & safety


The massification of exchanged data, the heterogeneity of storage and processing media and the diversification of uses induced by these data have triggered in recent years a multiplication of software and hardware attacks, affecting all types of media: connected objects deployed in homes and professional environments, critical systems and infrastructures, personal data, etc. Faced with this situation, cybersecurity has become a major issue to protect citizens and companies.

The activities of LIRMM researchers touch all aspects of cybersecurity: from IT aspects to hardware aspects. They are part of the national GDR security, IM, ISIS and SoC² and at the regional level in the recent Institute of Cybersecurity of Occitania. They give rise to numerous international academic and industrial collaborations. LIRMM innovations have led to the creation of two companies: Algodone and NinjaLab.

Themes and areas of activity

  • Multimedia data: image crypto-compression, securing 3D meshes, insertion of hidden data in the encrypted domain, steganography
  • Cryptography and its algorithmic foundations: design of advanced cryptographic protocols, algorithmic arithmetic, factorization and discrete logarithm algorithms
  • Post-quantum cryptography: design of post-quantum systems, mathematical foundations of the underlying objects, integration and hardware attacks of post-quantum algorithm implementations
  • Privacy protection: anonymity, differential privacy, anonymous data management
  • Secure distributed computing protocols: distributed cryptography, blockchain, secure database computing
  • Hardware-software interface: memory corruption, code-breaking, code injection
  • Hardware attacks and countermeasures: covert channel attacks, fault injection, micro-architectural (cache-based attacks, rowhammer and embedded test devices)
  • Integrity and authenticity of embedded systems: prevention and detection of hardware trojans, overproduction, IP protection and authentication.
  • Hardware design for security: processors, gas pedals, countermeasures.
  • Security: software security, dependability, formal methods, fault tolerance in various application domains (robotics, embedded systems, …)
