I am currently interested in Wireless Sensor Network research, specifically in “Participatory” Sensor Networks. This is an exciting new paradigm where people voluntarily collect information from their local environment using personal devices like mobile phones and then share this information using existing communication infrastructure (like the cellular network). Voluntary participation coupled with the use of personal mobile devices as sensors, opens up a whole new world of possibilities where it becomes easy for anyone to help in better understanding their environment. It would be like taking citizen science to the next level. However, this also makes it easy for anyone to abuse the system: such as deliberately sharing incorrect information.
My interest lies mainly in developing secure protocols specific to the needs of participatory sensing applications. The goal is to prevent or identify any fabrication of the data collected and hold the culprits accountable while protecting the privacy of honest participants.
We use a unique trusted-platform based approach to simplify the required security solutions and provide irrefutable guarantees about the integrity of the collected data.
