Managing increasingly complex systems effectively and securely

Complex systems are characterized by autonomy in decision and action to perform  tasks using high-performance computing, artificial intelligence, large data bases and global communication networks. 

Leti is proposing new solutions to address the following market requirements:

  • Innovative system architectures leveraging distributed functions like sensing, actuating, processing (locally or remotely), energy harvesting and storage, and communication

  • Innovative hardware (sensors, actuators, energy harvesters, communication circuits, antennas) and embedded low-power processing solutions. Their integration into objects or materials through extreme miniaturization or their distribution on thin, flexible and stretchable supports is also being addressed

  • Wireless communications with improved efficiency, reliability, latency for real-time applications

  • Securing individual circuits and communicating objects often exposed to attackers and/or severe environments. Innovative strategies are required to guarantee the integrity, authenticity and confidentiality of information in the devices, including cryptography and cryptosystems for long-term security
