Team presentation

The POPS research group investigates solutions to enhance programmability, adaptability and reachability of small objects designated by POPS (Portable Objects Proved to be Safe). The POPS set contains small devices like smart cards, RFID tags or personal digital assistant which are characterized by limited resources, high mobility and high security level in spite of untrusted environment. The development of applications integrating POPS suffers from lack of "reachability" of such platform. Indeed, most of POPS are not easy to program and high level of expertise is needed to produce software in such limited operating systems and devices. Moreover, POPS mobility induces sudden and frequent disconnection, long roundtrip times, high bit error rates and small bandwidth. Hence, POPS system has to adapt itself to application requirements or modification of its environment. In that context, we are conducting research in the connected areas of embedded systems and mobile networking.

Research themes

  • Embedded Operating Systems, focusing on operating systems and virtual machines scalability (in term of memory, microchip performance and energy) where smart cards are our reference target. Our main activities deal with the scalability of Java abstractions (the Java-In-The-Small sub-project) and efficient, extensible and safe hardware management (the Camille NG sub-project).
  • Mobile Networking, focusing on communication protocols on wireless network architectures, in ad hoc or wireless LAN mode, using or not fixed infrastructure. Our protocols aims to ensure secure connectivity of dense large networks which are constituted of small devices with high mobility.

International and industrial relations

  • Gemplus, smart card manufacturer.
  • TagSys, RFID tags manufacturer.
