A Secure Data Sharing and Query Processing Framework via Federation of Cloud Computing
Prof. Sanjay K Madria,
Missouri University of Science and Technology –
Due to cost-efficiency and less hands-on management, data owners are outsourcing their data to the cloud, which can provide access to the data as a service. However, by outsourcing their data, the data owners lose control and privacy, as the cloud provider becomes a third party service provider. At first, encrypting the data by the owner and then exporting it to the cloud seems to be a good approach to preserve the privacy. However, there is a potential efficiency problem with the outsourced encrypted data when the data owner revokes some of the users’ access privileges. An existing solution to this problem is based on symmetric key encryption scheme but it is not secure when a revoked user rejoins the system with different access privileges for the same data record. In this talk, I will discuss an efficient and Secure Data Sharing (SDS) framework using a homomorphic encryption and proxy re-encryption scheme that prevents the leakage of unauthorized data when a revoked user rejoins the system. I will also discuss modification to the underlying SDS framework and present a new solution based on the data distribution technique to prevent the information leakage in the case of collusion between a revoked user and the cloud service provider. A comparison of the proposed solution with existing methods is provided in detail. Furthermore, I will demonstrate how the existing work can be utilized in the proposed framework to support secure query processing. I will provide a detailed experimental analysis of the proposed framework on Amazon EC2 and discuss its practical relevance.

He is a full professor in the Department of Computer Science at the Missouri University of Science and Technology (formerly, University of Missouri-Rolla, USA). He has published over 225 Journal and conference papers in the areas of mobile data management, XML Data Management, sensor computing, cloud and cyber security. He won five IEEE best papers awards including IEEE MDM 2011, IEEE MDM 2012 and IEEE SRDS 2015. He is the co-author of a book published by Springer in Nov 2003. He has served/serving in International conferences as a general co-chair, pc co-chair, and steering committee member (like for MDM, SRDS and others), and presented tutorials in the areas of mobile data management and sensor computing. He has also been awarded JSPS (Japanese Society for Promotion of Science) visiting scientist fellowship in 2006 and ASEE (American Society of Engineering Education) fellowship at AFRL from 2008 to 2016. In 2012, he was awarded NRC Fellowship by National Academies. He received faculty excellence and research awards in years 2007, 2009, 2011, 2013 and 2015 from his university for excellence in research, teaching and service. He served as an IEEE Distinguished Speaker, and currently, he is an ACM Distinguished Speaker and IEEE Senior Member as well as IEEE Golden Core Awardee.
