Data and knowledge play a key role in both current and future GRIDs. The issues concerning representation, discovery, and integration of data and knowledge in dynamic distributed environments can be addressed by exploiting features offered by GRID Technologies. Current research activities are leveraging the GRID for the provision of generic- and domain-specific solutions and services for data management and knowledge discovery.Knowledge and Data Management in GRIDs is the third volume of the CoreGRID series and brings together scientific contributions by researchers and scientists working on storage, data, and knowledge management in GRID and Peer-to-Peer systems. This volume presents the latest GRID solutions and research results in key areas of knowledge and data management such as distributed storage management, GRID databases, Semantic GRID and GRID-aware data mining.Knowledge and Data Management in GRIDs is designed for a professional audience, composed of researchers and practitioners in industry. This book is also suitable for graduate-level students in computer science.

In additiontheworkshopaimsto bringtogetherresearchersandpractitionersin- lated disciplines and encourage interchange and practical co-operation between academia and industry. Although this is the ?rst ever WISTP event, the response from researchers wassuperbwithover68paperssubmittedforpotentialinclusionintheworkshop and proceedings. The submissions were reviewed by at least three reviewers, in most cases by four, and for program committee (PC) papers at least ?ve reviewers. This long and rigorous process was only possible thanks to the hard work of the PC members and additional reviewers, listed in the following pages. We would like to express our gratitude to the PC members, who were very supportive from the very beginning of this project. Thanks are also due to the additional expert reviewers who helped the PC to select the ?nal 20 workshop papers for publication in the proceedings. Of course we highly appreciate the e?orts of all the authors who submitted papers to WISTP 2007. We hope they will contribute again to a future edition and encourage others to do so.

This volume contains the 12 papers presented at the WISTP 2009 conference, held in Brussels, Belgium in September 2009. WISTP 2009 was the third int- national workshop devoted to information security theory and practice. WISTP 2009 built on the successful WISTP 2007 and 2008 conferences, held in Heraklion, Crete, Greece and Seville, Spain in May 2007 and May 2008, - spectively. The proceedings of WISTP 2007 and WISTP 2008 were published as volumes 4462 and 5019 of the Lecture Notes in Computer Science series. This workshop received the following support: – Co-sponsored by IFIP WG 11. 2 Small System Security – Co-sponsored by VDE ITG – Technical sponsorship of the IEEE Systems, Man & Cybernetics Society – Supported by the Technical Committee on Systems Safety and Security – Organized in cooperation with the ACM SIGSAC – Supported by ENISA – Supported by the Institute for Systems and Technologies of Information, Control and Communication (INSTICC) These proceedings contain 12 original papers covering a range of theoretical and practical topics in information security. For the purposes of the organi- tion of the WISTP program, the papers were divided into four main categories, namely: – Mobility – Attacks and Secure Implementations – Performance and Security – Cryptography The12papersincludedherewereselectedfromatotalof27submissions. The refereeing process was rigorous,involving at least three (and mostly four or ?ve) independent reports being prepared for each submission.
