Rapport et  Présentation de Mastère : Authentification de l'utilisateur dans les réseaux de capteurs sans fil de Amira Mnif 2010/2012
General Introduction :

The progress made in recent decades in the fields of microelectronics,

micromechanics, and wireless communication technologies have produced with a reasonable

cost and a few cubic millimeters in volume components named sensor nodes.

These small devices equipped with advanced sensing functionalities and a small processor

operate independently and communicate with each other via short-range transmissions in

order to build a global view of a monitored region. Thus, new areas of investigation have been

opened to provide remote monitoring and data processing in complex environments through

sensor nodes which form collectively a Wireless Sensor Network (WSN). The application

scenarios for WSNs are several, including military supervision, commercial, environmental,

medical, manufacturing and home automation, despite this advances, security continues to be

a main challenge that must be resolved.
