Achieving Secure Communication Over Wireless Channels
Mon, Mar 26, 2007 @ 10:45 AM - 11:45 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Yingbin Grace Liang,
Princeton UniversityAbstract: In this talk, I will begin with an overview of research in information theory for wireless communications, including a summary of my contributions to this area. The main focus of the talk will be on my recent work on information-theoretic security for wireless communication networks.Two basic wireless communication scenarios are broadcast communication from one transmitter to multiple receivers and multiple access communication from multiple transmitters to one receiver. While security issues were addressed for broadcast communication by Wyner, Csiszar and Korner in 70's, security issues in multiple access communication have been open for three decades. In this talk, I will present our work towards resolving these open problems.I will first introduce the channel that we have identified to model wireless multiple access communication, where security issues arise naturally. For this channel, we have developed novel techniques to characterize reliable communication rates under secrecy constraints (possibly perfect secrecy). I will also postulate the general coding design principles that are essential to achieve secure communication.Biography: Yingbin Liang received the Ph.D. degree in Electrical Engineering from the University of Illinois at Urbana-Champaign in 2005. Since September 2005, she has been working as a postdoctoral research associate at Princeton University. Her research interests include wireless communications and networks, information security, and information theory.Dr. Liang was a Vodafone Fellow at the University of Illinois at Urbana-Champaign during 2003-2005, and received the Vodafone-U.S. Foundation Fellows Initiative Research Merit Award in 2005. She also received the M. E. Van Valkenburg Graduate Research Award from the ECE department, University of Illinois at Urbana-Champaign, in 2005.Host: Giuseppe Caire, caire@usc.edu

An Overview of Research Activities of the Systems and Applied Mechanics.....
Mon, Mar 26, 2007 @ 02:00 PM - 03:00 PM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
An Overview of Research Activities of the Systems and Applied Mechanics Laboratory at Ecole Polytechnique de Tunisie:
Call for International CollaborationByDr. Slim Choura, s_choura@yahoo.comSystems and Applied Mechanics Laboratory
Ecole Polytechnique de Tunisie
La Marsa, 2078, TUNISIAABSTRACTAn overview of the research activities conducted by the members of the Systems and Applied Mechanics Laboratory (SAML) at Ecole Polytechnique de Tunisie, Tunisia, is first presented. Specific activities within the area of Civil Engineering are more emphasized. Second, a summary of the application of a rational methodology for the structural assessment of reinforced concrete bridges and historical buildings will be given. This methodology is based on ambient vibration measurement, identification modal signature and linear and nonlinear finite element model updating of these structures. Finally, SAML future research activities, which call for international collaboration, are presented.Location: Kaprielian Hall (KAP) - rielian Hall 203

Efficient and Private Distance Approximation
Mon, Mar 26, 2007 @ 03:30 PM - 05:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
David WoodruffMassachusetts Institute of TechnologyAbstract:I will cover two of my results in distance approximation. Consider the setting in which two parties want to approximate the distance between their input vectors.First I will consider l_2, the Euclidean distance. It is known how to approximate l_2 efficiently. However, if we require the protocol to be private, that is, neither party can learn more than what follows from the distance and his/her private input, much less is known. Feigenbaum, Ishai, Malkin, Nissim, Strauss, and Wright [FIMNSW] gave a protocol with O(sqrt{d}) communication for privately approximating the Hamming distance of two d-dimensional vectors. I will give a private protocol with polylog(d) communication for l_2. As a special case, this yields an exponential improvement over [FIMNSW] for the Hamming distance.Next I will consider the l_p distance, for p > 2. This problem is motivated by recent research in streaming algorithms, and has applications in database theory. I will give a 1-round protocol achieving optimal communication for this problem, up to logarithmic factors. It is easy to implement in the streaming model, and consequently resolves the main open question of a 1996 paper of Alon, Matias, and Szegedy.Joint work with Piotr Indyk (STOC 2005, TCC 2006).Biography: David Woodruff is a fifth-year PhD student at MIT. He received his master's in computer science, and B.S. degrees in both computer science and mathematics, all from MIT. He is interested in theoretical computer science, particularly algorithms, complexity theory, and cryptography.Hosted by David KempeRefreshments will be served.
