Recent technological advances have made it possible to develop distributed sensor networks consisting of a large number of low-cost, low-power, and multi-functional sensor nodes that communicate in short distances through wireless links. Such sensor networks are ideal candidates for a wide range of applications, such as monitoring of critical infrastructures and military operations. In hostile environments, the security and resiliency of such sensor networks become a critical issue. However, it is very challenging to build secure and resilient sensor networks due to several unique features of sensor networks, such as the resource constraints on sensor nodes and exposure to node captures and physical attacks. In this talk, I will present some recent results on mitigating Denial of Service (DoS) attacks against broadcast authentication in wireless sensor networks, as well as secure and DoS-resistant code dissemination, an application that requires broadcast authentication.
Peng Ning is an Associate Professor of Computer Science at NC State University. He was an Assistant Professor at NC State University from August 2001 to July 2006. He joined NC State University in August 2001 after graduating from George Mason University with a PhD degree in Information Technology. He received a BS degree in Information Science and an ME degree in Communication and Electronic System in 1994 and 1997, respectively, both from the University of Science and Technology of China. His research interests are mainly in computer and network security. He is the recipient of an NSF CAREER award. His research has been supported by the National Science Foundation (NSF), the Army Research Office (ARO), the Advanced Research and Development Activity (ARDA), SRI International, and the NCSU/Duke Center for Advanced Computing and Communication (CACC). He is on the editorial boards of the Journal of Computer Security, Ad-Hoc Networks, Ad-Hoc & Sensor Networks: an International Journal, and IET Proceedings Information Security. He served as the Program Chairs of ACM SASN '05 and ICICS '06, and the General Chair of ACM CCS '07. He is a founding Steering Committee member of ACM WiSec, which results from the merger of the ACM WiSe, ACM SASN, and ESAS workshops. He has also served on the organizing committees or program committees for over thirty technical conferences or workshops related to computer and network security. He is a member of the ACM, the ACM SIGSAC, the IEEE, and the IEEE Computer Society.
