CERG Seminars are held in the Science and Technology II building on the GMU Fairfax campus unless noted otherwise. Parking is available in the Sandy Creek parking deck just to the side of Science and Technology II. Directions to the campus can be found here. The seminar talks are usually 45 to 60 minutes long and are open to the public. If you wish to be notified about future seminars, please send an e-mail to Jens-Peter Kaps.

Multi-user Broadcast Authentication in Wireless Sensor Networks

Dr. Kui Ren, Illinois Institute of Technology
Date: Tuesday, November 27th, 3 pm - 4 pm, Location: Science and Tech II, Room 230 A


A wireless sensor network (WSN) usually consists of a large number of ultra-small, lowcost devices that have limited energy supply, computation, memory, and communication capacities. WSNs have drawn a lot of attention recently due to their broad applications in both military and civilian domains. Security is essential to ensure the success of WSN applications, especially for those mission-critical applications working in unattended and even hostile environments. However, security design in WSNs has ever been a challenging task due to their open, distributed, compromise-prone, and resourceconstrained nature. In fact, security of WSNs is currently a very active topic and there are many interesting and challenging research issues. In this presentation, we will focus on multi-user broadcast authentication in WSNs, which is key to the security of broadcast/multicast communication in WSNs. Some other interesting security research topics we have worked on will also be briefly discussed as time permits. Finally, we will conclude the presentation by discussing some future research directions in the area of wireless network security.
