Low-Cost Secret-Sharing in Sensor Networks [PDF]
2010 IEEE 12th International Symposium on High Assurance Systems Engineering, 2010 Cet article présente un technique simple qui permet de sécuriser les communications dans un réseau de capteurs. Dans le contexte des réseaux de capteurs, la limitation au niveau des ressources (puissance de calcul, eńergie, communication) fait que l'usage de la cryptographie asymétrique classique n'est pas envisageable. La technique proposée repose sur

A low-cost CMOS neurological sensor array [PDF]
SPIE Proceedings, 2005 Current methods used to study neural communication have not been able to achieve both good spatial and temporal resolution of recordings. There are two ways to record synaptic potentials from nerve endings: recordings using single or dual intracellular or extra cellular metal electrodes give good temporal resolution but poor spatial resolution, and ...
