Security and privacy for emerging large-scale mobile systems
Abstract: 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. Or, Location Based Services (LBS) can provide precise data that are most relevant to the user whereabouts. Nonetheless, 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, or to thwart LBS or PS data pollution. At the same time, submission of sensed data, frequent transmission of vehicle information, or location-based queries, they all reveal location and other sensitive user information. In this seminar, we discuss how to address these concerns, especially because both security and privacy protection are necessary; in fact, they can be prerequisites towards broad acceptance and deployment. We consider the threat landscape for such emerging mobile systems and discuss solutions to secure their operation and protect their users' privacy.
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 a tenured Associate Professor at KTH, Stockholm, Sweden, where he leads the Networked Systems Security group. His research agenda includes a gamut of security and privacy problems, with emphasis on wireless networks. At KTH, he is affiliated with the ACCESS center, leading its Security, Privacy, and Trust thematic area, as well as the ICES center, leading its Industrial Competence Group on Security. Panos is a Knut and Alice Wallenberg Academy Fellow and he received a Swedish Science Foundation Young Researcher Award. He has delivered numerous invited talks, keynotes, and panel addresses, as well as tutorials in flagship conferences. Panos currently serves as an Associate Editor of the IEEE Transactions on Mobile Computing and the ACM/IEEE Transactions on Networking. He has served in numerous program committees, with leading roles in numerous occasions; recently, recently, in 2016, as the program co-chair for the ACM WiSec and the TRUST conferences; he will serve as the general chair of the ACM WISec (2018) and PETS (2019) conferences. Panos is a member of the Young Academy of Europe. His group webpage is: www.ee.kth.se/nss.
