Defending Sensor Networks Against Attacks
A wireless sensor network consists of a collection
of sensors, which have the capability of signal sensing,
data processing, and message communication. The sensor
network is highly constrained in resources. It is
used in many different kinds of applications, such
as monitoring the battlefield. Most of the applications
where different types of attacks occur are security-sensitive.
But traditional security protocols are designed for
resource rich machines to support large computation
and are not applicable to sensor networks due to resource
limitations, ad hoc nature and intermittent connectivity
in sensor networks. My research issues include:
• Study different types of attacks’ behavior
in sensor networks
• Secure routing in sensor networks against
different types of attacks
• Key management in sensor networks
• Secure data aggregation
