Sensor Network Security

In distributed sensor networks large numbers of tiny sensor nodes communicate among themselves remotely or locally. It has the potential to enable a wide range of applications, but they pose serious security design challenges due to ad hoc nature of the communication and constraints such as limited energy, processor speed and memory. To secure such a wireless network, efficient key management techniques are important. Existing techniques fail as they assume resource-equipped nodes. There are some recent security protocols that have been proposed for sensor networks and few of them have been implemented in a real environment.

We explored existing security protocols based on private/public key cryptography, Kerberos, Digital signatures and IP security. We also investegated the existing work on key management protocols for sensor networks. Now we are trying to develop new approaches for providing group key management, cluster head security and dynamic key computation.
