Abstract (Summary of the Work)

An Unattended Wireless Sensor Network (UWSN) is a type of sensor network where a trusted sink visits each node periodically to collect the data. Due to offline nature of this network, every node has to secure the sensed data until next visit of the sink i.e. until data is being sent to the sink.We will consider UWSNs operating in hostile environment where the goal of an attacker is to prevent targeted data from ever reaching the sink or to send corrupted data to the sink. So, in a UWSN data confidentiality and data authenticity are required. Besides we have to take care of survivability of sensed data.In this thesis we have presented a scheme that provides authenticity, confidentiality and survivability of sensed data in efficient manner. All these issues were not addressed together in any of the previous scheme for securing UWSNs. We analyse the security performance of scheme and show that it enjoys high survivability, authenticity and confidentiality.
