Abstract

With the mature and popularity of P2P systems, there come out a lot of problems, such as selfish, dishonest, and malicious peer behaviors. So we need reputation systems to prevent a user’s bad behaviors and encourage a user’s good behaviors.

Professor Kai Hwang will share his experience with trust management and reputation systems for P2P computing, and his presentation will cover the evolution of Internet computing and Web services, trust integration and security binding issues, global peer reputation aggregation methods, the PowerTrust for DHT-based systems, the GossipTrust for unstructured P2P networks, relative performance of P2P reputation systems and some further research/development challenges.

Speaker’s bio:

Kai Hwang is a Professor of Electrical Engineering and Computer Science and Director of Internet and Grid Computing Laboratory at the University of Southern California. He received the Ph.D. in Electrical Engineering and Computer Science from the University of California, Berkeley in 1972. Prior to joining USC in 1985, he has taught at Purdue University for many years. He is the founding Editor-in-Chief of the Journal of Parallel and Distributed Computing. He is also an editor of IEEE Transactions on Parallel and Distributed Systems.

Dr. Hwang has authored or coauthored 4 books and 200 scientific papers in refereed Journals and conferences. He was elected an IEEE Fellow in 1986 for making significant contributions in computer architecture, digital arithmetic, and parallel processing. His work was ranked by the CiteSeer.Continuity in August 2006 among the top 0.25 % most cited authors in Computer Science out of 790,329 authors in the database.

Dr. Hwang has chaired numerous ACM/IEEE Conferences and presented over 20 keynote addresses in major international conferences. He has lectured worldwide and performed advisory work for IBM Fishkill, MIT Lincoln Lab., ETL in Japan, Academia Sinica in China, INRIA in France, and GMD in Germany. Presently, he leads the NSF-supported GridSec Project at USC. His group develops P2P trust models, DHT overlay networks, reputation systems, and distributed defense systems against Internet worm outbreaks and DDoS attacks.
