Wireless sensor and actuator networks are
potentially useful building blocks for cyber-physical systems.
Those systems must typically guarantee high-confidence
operation, which induces strong requirements on the
dependability of their building blocks, including the wireless
sensor and actuator network. Dependability means resistance
against both accidental failures and intentional attacks, and it
should be addressed at all layers of the network architecture,
including the networking protocols and the distributed
services built on top of them, as well as the hardware and
software architecture of the sensor and actuator nodes
themselves. Within this context, in this paper, I focus on the
security aspects of aggregator node election and data
aggregation protocols in wireless sensor networks(WSN).

In this paper, I proposed two private aggregator node
election protocols for WSN that hide the elected
aggregator nodes from attacker, who, therefore, cannot
locate and disable them. My basic protocol provides fewer
guarantees than my advanced protocol. Advanced protocol
hides the identity of the elected aggregator nodes even
from insider attackers, thus it handles node compromise
attacks too. The aggregation protocol allows the
aggregator nodes to collect sensor readings & respond to
queries of the operator, respectively. In aggregation and
query protocols are resistant to both external
eavesdroppers and compromised nodes participating in the
protocol. The communication in the advanced protocol is
based on connected dominating set, which suits to WSN.
