Abstract:
Wireless sensor networks represent an interesting environment for a
number of problems related to distributed systems. They have got
specific restrictions (power consumption), unusual routing requirements
(nodes/motes have no idea about the network topology when deployed), and
the information produced by nodes gains value when aggregated, a space
for new security protocols exist. We have put some effort into
simulating security of key agreement protocols against an attacker
controlling only a fraction of the network (key infection, secrecy
amplification). The talk will briefly survey several existing key
management schemes and highlight some interesting results we have
obtained for key infection protocols.
