A Distributed Authentication Scheme for a Wireless Sensing System

CENG SEMINAR SERIES"A Distributed Authentication Scheme for a Wireless Sensing System"Prof. Hyunyoung LeeDepartment of Computer ScienceUniversity of DenverAbstract:Wireless sensor technologies are becoming more efficient and smaller in size and as a result, they are becoming more widely used for a variety of applications. However, due to their limited computational, energy, and storage resources, these devices can only perform relatively simple tasks. Furthermore, implementing strong security in sensor networks has often been disregarded because most common cryptographic schemes are too expensive. Nonetheless, sensor networks may often relay critical data, thus, security must be a high priority. We propose a novel distributed authentication scheme that is efficient and robust using the well-known concepts of "secret sharing" cryptography and group "consensus." We prove that our scheme is well-suited to the resource-deprived nature of networked sensing systems and demonstrate that it requires a minimal message and bit complexity.Bio:Hyunyoung Lee received her Ph.D. degree from Texas A&M University, M.A. from Boston University, M.S. and B.S. from Ewha University in South Korea, in 2001, 1998, 1992, and 1987, respectively, all in Computer Science. She is currently an Assistant Professor of Computer Science at the University of Denver. She is a member of the IEEE and the ACM. She was a Member of Technical Staff at Korean Air, and a consultant at Bellcore (now Telcordia). Her areas of research include distributed systems and algorithms, wireless networks, mobile ad hoc networks, and fault-tolerant computing.Host: Prof. Michel Dubois, Ext. 04475
