LERSAIS Speaker – April 20, 2007


SIS welcomes Dr. Feng Cao, Software Engineer at CISCO Systems, as the next speaker in the LERSAIS Seminar Series.  Dr. Cao will discuss “Providing Secure Services in Peer-to-Peer Communications Networks with Central Security Servers” on Friday, April 20 from 2:00 pm to 3:30 pm in Room 404 of the IS Building.  The series is hosted by the Laboratory of Education and Research on Security Assured Information Systems at the School of Information Sciences. 

Dr. Cao will examine how various applications based on Peer-to-Peer (P2P) technology have being gaining attention for their innovative approaches to providing value-added services. At the same time, the trend has introduced new research topics on how to provide the secure services inside new distributed P2P environments.

This talk outlines a generic architecture for providing secure information in P2P IP Networks. Some secure techniques and components are shown to guarantee privacy of various information sharing services. Session Initiation Protocol (SIP) is demonstrated to provide the basic operations for this architecture. Some open research topics are discussed for further studies.

Dr. Feng Cao received his Ph.D. degree in Computer Science from the University of Minnesota, Minneapolis, in 1997. He received his B.S. and M.S. in Applied Mathematics from Tsinghua University, Beijing, in 1990 and 1992.  He has been with several leading research institutions and industrial organizations, including SGI Cray Research, Honeywell Technology Center, NTT Labs, and Cisco Systems. He has led international teams on various research and development projects in network security, video conferencing, Voice-Over-IP, and Quality of Service. He has been involved in international standards activities as part of the Internet Engineer Task Force (IETF) and Telecommunication Industry Association (TIA).
