Security and Privacy for Emerging Large-Scale Mobile Systems 

Versatile wireless networking and mobile computing platforms transform our environments and processes into intelligent ones. For example, vehicular communication (VC) systems can make transportation safer and more efficient. Or, participatory sensing (PS) systems, leveraging smartphones with increasingly rich sensing capabilities, can provide measurements practically from everywhere without dedicated sensor deployment. However, to reap the benefits of such systems, it is necessary to secure their operation and protect the privacy of their users. Security is necessary, for example, to control the access to PS tasks or to ensure the authenticity of VC messages. At the same time, submission of sensed data, frequent transmission of vehicle information, or location-based queries, they all reveal location and other sensitive PS or VC user information. In this seminar, we discuss how to address these concerns. We first discuss PS security and privacy, including how to ensure the PS-ed data trustworthiness. We then connect to related developments for VC systems, notably considering identity and credential management. Finally, we briefly link such a security infrastructure to decentralized privacy protection for location-based service (LBS) users.

Panagiotis (Panos) Papadimitratos earned his Ph.D. degree from Cornell University, Ithaca, NY, in 2005. He then held positions at Virginia Tech, EPFL and Politecnico of Torino. Panos is currently an Associate Professor at KTH, where he leads the Networked Systems Security group. His research agenda includes a gamut of security and privacy problems, with emphasis on wireless networks. Group web page: www.ee.kth.se/nss.
