题 目：Toward Privacy-Assured Data Services in Cloud Computing
Cloud Computing has emerged as a new enterprise IT infrastructure, in which databases and applications are moved into the servers in the large data centers on the Internet (i.e. the cloud). External users can enjoy massively scalable and elastic data, software, and hardware capabilities as a service using Internet technology.
As more and more information of individuals and companies is placed in the cloud, data security and privacy becomes a critical concern. Traditional data security mechanisms, such as access control, place full trust on the servers and rely on the servers to enforce the security policies. However, in cloud computing, the cloud servers are not necessarily in the same trust domain as the cloud users and users would not want the servers to learn the sensitive information of theirs.
In this talk, we will go through several unique challenges of assuring user privacy in outsourced cloud data services. We will start with the secure data storage and sharing problem under a challenging multi-owner, multi-user, and semi-trusted server setting. Two more problems - public integrity verification/auditing of outsourced cloud data and privacy-preserving search over encrypted cloud data will also be addressed. We will point out some technical challenges and practical problems as well as discuss state-of-the-art solutions toward providing privacy-assured data services in cloud computing.
Wenjing Lou is an associate professor in the Computer Science department at Virginia Polytechnic Institute and State University, and a co-director of the Complex Networks and Security Research (CNSR) lab. Prior to joining Virginia Tech in 2011, she was on the faculty of Worcester Polytechnic Institute from 2003 to 2011.
She received a Ph.D. in Electrical and Computer Engineering from University of Florida. She received a B.S. and an M.S. in Computer Science and Engineering from Xi'an Jiaotong University.
She was named Joseph Samuel Satin Distinguished fellow in 2006 by WPI. She was a recipient of the U.S. National Science Foundation Faculty Early Career Development (CAREER) award in 2008. She received the Sigma Xi Junior Faculty Research Award at WPI in 2009.
Her current research interests include wireless network security and data security and privacy in cloud computing. She is currently serving on the editorial boards of IEEE Transactions on Parallel and Distributed Systems and IEEE Wireless Communications Letters. She is a past editor for IEEE Transactions on Wireless Communications, IEEE Transactions on Smart Grid, Elsevier Computer Networks, and Springer Wireless Networks. She has served as TPC co-chair for the security symposium of several IEEE conferences, including IEEE Globecom 2007, IEEE ICCCN 2009, IEEE ICC 2010, IEEE PIMRC 2011, and IEEE Globecom 2012. She is the TPC co-chair for SECRYPT 2012, the mini-conference co-chair for IEEE INFOCOM 2013, and the panel co-chair for IEEE INFOCOM 2014. She serves as TPC Area Chair for IEEE INFOCOM 2013&2014, and IEEE ICNP 2013. She serves as TPC member for many leading security and networking conferences, including IEEE INFOCOM, ACM WiSec, ACM MobiHoc, IEEE ICNP, ICDCS, ESORICS, IEEE PerCom. She is the lead co-founder and TPC co-chair for the First IEEE Conference on Communications and Network Security (IEEE CNS), to be held in Washington DC in October 2013.
