Flexible and Secure Cloud Computing: The FlexCloud Approach (Tentative)

Prof. Dr. Alexander Schill
Dresden University of Technology, Germany


Cloud computing is a very common trend and enables users to dynamically access server resources on demand in order to safe infrastructure costs and to shift responsibilities from the user client to a backend infrastructure provider. However, it also comes with many challenges due to proprietary solutions, due to issues of trust and reliability, and due to lack of control regarding the information flow.

The talks outlines the potential of cloud computing and also its challenges. It then presents a novel solution name FlexCloud that acts as a smart intermediary between the end user and different cloud providers in the internet or intranet. The main goal is to implement the vision of a so-called p-cloud (or personal cloud) that can be customized according to the user requirements and the given environment. Most importantly, confidentiality, integrity, and availability of processed information are addressed. In addition to the selective use of cryptographic mechanisms, systematic information dispersal algorithms are employed in order to make cloud storage more reliable.

Eventually, it is shown how the approach can be generalized towards a full cloud lifecycle vision with service-level agreements, dynamic cloud configuration, cloud monitoring at runtime, and cloud adaptation and optimization on demand. The results are backed by a prototype implementation of a secure cloud storage system within the FlexCloud project.


Alexander Schill is a professor for Computer Networks and Distributed Systems at Dresden University of Technology, Germany. His major research interests are service-oriented computing, quality of service, and cloud computing. Current projects focus on advanced software platforms and use cases for these areas together with several industry partners. He holds a M.Sc. and a Ph.D. in Computer Science from the University of Karlsruhe, Germany, and received a Dr.h.c. from Universidad Nacional de Asuncion, Paraguay. He is also a member of the advisory board of the MasterĀ“s Program on Information Technology at the Royal University of Phnom Penh.

From 2000 to 2006, he acted as dean of the Faculty for Informatics at his university in Dresden. Prof. Schill also worked with the IBM Thomas J. Watson Research Center, Yorktown Heights, New York, and has been involved in various industry projects. He is the author or co-author of a large number of publications on computer networking, including several books.

Keynote Speech II

Link Mining and Information Retrieval from Complex Networks (Tentative)

Prof. Ei-Ichi Osawa
Future University Hakodate, Japan


Search engines such as Google and Yahoo have been widely and commonly used to retrieve information from World Wide Web. These search engines work well when one has concrete and exact keywords to identify the related pages. However, there is a case that one cannot successfully find the exact keywords to retrieve information which he or she wants to find. Also, there will be a case that one wants to find related pages that does not necessarily contain the original keywords that is used to invoke the search. In these cases one sometimes needs to perform so called net surfing, which is usually a time consuming task, to find related information. In this talk, we present alternative approach for information retrieval to cope with these cases.

The recent study of networks in computer science, such as computer networks, the WWW, and social network services, shows that very large real-world networks are networks with non-trivial topological features (and are sometimes called complex network). These features include a heavy tail in the degree distribution, a high clustering coefficient, and hierarchical structures. Among these features, we are especially interested in community structure of complex network. A network is said to have community structure if the nodes of the network can be grouped into sets of nodes such that each set of nodes is densely connected internally. In WWW, if we can find a community of pages that includes the page one is initially interested in, one might successfully be able to get access to other highly related pages that don't necessarily include the keywords.

Several efficient community detection algorithms have been proposed. However, these algorithms tend to detect a excessive community that includes pages that are less related. We have devised a couple of methods to improve precision and recall of community detection. These methods and some empirical results obtained from experiments based on the Wikipedia are presented.


Dr. Ei-Ichi Osawa received a B.S. in mathematics from Tokyo Institute of Technology in 1982 and Ph.D. in computer science from Keio University in 1996. After he completed his undergraduate study, he joined Sony Corporation, and later Sony Computer Science Laboratories, Inc. Since the year 2000, he has been a professor in artificial intelligence at Future University Hakodate (FUN), and was the dean of the Graduate School of Systems Information Science at FUN. His general research interests include open distributed computing systems, multiagent organization, massively multiagent systems, multi robot coordination, interface agent, and complex networks. He received several awards from IPSJ (Information Processing Society of Japan) and JSAI (Japan Society for Artificial Intelligence) for his research achievements in these research areas. He has long been served for many international conference including IJCAI (International Joint Conference on Artificial Intelligence), ICMAS (International Conference on Multi Agent Systems), and AAMAS (International Conference on Autonomous Agents and Multiagent Systems) as a program committee member and/or a reviewer. Also, he served for AAMAS-06 as the local organization chair. Additionally, he was a member of the board of trustees of JSST from 2006 to 2010.
