Title:
Secure Cooperative Channel Establishment in Wireless Sensor Networks

Speaker:
Mauro Conti

Abstract:
This talk presents the ECCE Protocol, a new distributed, probabilistic,
cooperative protocol to establish a secure pair-wise communication channel
between any pair of sensors in a Wireless Sensor Network (WSN).
The main contribution of the ECCE Protocol is to allow the set up of a
secure channel between two sensors (principals) that do not share any
pre-deployed key.
This feature is obtained involving a set of sensors (cooperators) in the
channel establishment protocol. Further, the security provided by the
protocol is adaptive with the level of threat in the WSN, that is, the
higher the security threat, the more cooperators can be involved to
enhance the resiliency of the channel.
We provide extensive simulations of the proposed scheme, which show that
ECCE increases both the probability of a secure channel set up and the
probability of channel resilience with respect to other protocols. ******
