About Since september 2008, I have been working in Information Security and Privacy Lab, HYU. My research area is Information Security and Privacy. More precisely I have been working on VANET (Vehicular Ad Hoc NETwork) security. I have published papers on privacy issues in VANET, Attacks, Beaconing, Local and Extended views in VANET and more. Recently i have started to work on a new emerging field called VANET-based Clouds which is a bridge to combine VANET and Cloud Computing, and have published couple of papers in VANET Clouds while still working on others.
