Collaborative authentication in unattended WSNs
Roberto Di Pietro, Claudio Soriente, Angelo Spognardi, Gene Tsudik · 2009
An unattended wireless sensor network (UWSN) might collect valuable data representing an attractive target for the adversary. Since a sink visits the network infrequently, unattended sensors cannot immediately off-load data to some safe external entity. With sufficient time between sink visits, a powerful mobile adversary can easily compromise sensor-collected data.
