Online pre-enrolment for our training programs is now open.
The research hub wishes to actively contribute to the development of efficient, autonomous, reconfigurable and intelligent communication systems.
ENSTA Bretagne researchers primarily contribute to the “Security, Intelligence and Integrity of Information” (SI3) team.
The team designs and develops methods, algorithms and solutions for securing the physical layer of future communications and transmission systems.
Its contributions also involve testing the deployed standards and systems or carrying out the corresponding “reverse engineering” for our institutional defense or national regulatory partners.
In this area, everything can be considered as a challenge, because most of the reception processing is generally performed blindly and/or with very severe operational constraints in terms of stealth, threshold of noise level, own or external interference, power consumption, spectral efficiency, security, etc.
These research topics are at the intersection of signal processing, mathematics, “classical” and quantum information theory, and require consideration of major criteria and constraints related to operational, confidential, secure and other hardware aspects of the considered applications.
The high potential of sensors is hampered by two major technological hurdles: the limited resources of their batteries and the difficulty collecting large datasets in real-time. This theme aims at outlining various mechanisms for collecting and analyzing data to overcome these challenges, on the basis of sensor network architecture (clustering).
The results obtained during testing have demonstrated the effectiveness of these mechanisms in terms of energy consumption, data precision and scope, and improve the performances of sensor networks.
The mechanisms proposed operate at three network levels. They aim at reducing the quantity of data disseminated through the network while protecting the integrity of information.
These programs are conducted with the military hospital and teaching hospital (CHRU) in Brest.
By estimating the characteristics of the transmission channel to improve information transmission and protection.
