In conjunctionwithSTA2011,aseriesofworkshopswereheld.Theyweremeantto facilitate the exchange of ideas and experiences between active researchers,and to stimulate discussions on new and emerging topics in line with the conference topics. We see the workshops as a necessary extension of the main conference. STAhasestablisheditselfrapidlyasahigh-qualityconferencewithahighlycom- petitive selectionprocess.The following workshopswere approvedandaccepted for inclusion in the STA 2011 program: – InternationalWorkshoponConvergenceSecurityinPervasiveEnvironments, (IWCS 2011) – InternationalWorkshoponSecurityandTrustforApplicationsinVirtualized Environments, (STAVE 2011) The programof eachof these workshopswas developed by a separate dedicated organizingteam and ProgramCommittee. The organizationof these workshops was made possible by the voluntary dedicated efforts of many individuals. We thank all the workshop organizers, the members of the Program Committees, and the additional reviewers for their excellent service to the community. We thank the authors for submitting papers to these workshops. June 2011 Changhoon Lee Jean-Marc Seigneur James J. (Jong Hyuk) Park Roland R. Wagner International Workshop on Convergence Security in Pervasive Environments (IWCS 2011) Preface On behalf of the Organizing Committees, it is our pleasure to welcome you to the first FTRA International Workshop on Convergence Security in Pervasive Environments (IWCS 2011), which was held in Loutraki, Greece, June 28–30, 2011. A recent emerging issue in information technology is the convergence of dif- ferent kinds of applications. Convergence brings a user-centric environment to provide computing and communication services. In order to realize IT advan- tages,weneedtheintegrationofsecurityanddatamanagementtobesuitablefor pervasive computing environments.However,there are still many problems and majorchallengeswaitingforustosolvesuchasthesecurityrisksinconvergence applications, which could appear when devices interact with different kinds of applications. Therefore, we need to explore convergence security in pervasive environments. IWCS 2011 addressedthe various theories and practical applications of con- vergence security in pervasive environments. It presented important results for improving application services and solving various problems within the scope of IWCS 2011. In addition, we believe it triggered further related research and technology developments that will improve our lives in the future. We sincerely thank all our Chairs and Committees that are listed on the following pages. Without theirhard work, the success of IWCS 2011 would not have been possible.We hope you find the proceedings of IWCS 2011 enjoyable and we would welcome any suggestions for improvement. Jose A.

These technologies allow organisations to increase the utilisa- tion of their IT infrastructure while lowering the overallcosts of ownership and accelerating the return on investment. Asvirtualisationincreasesthesharingofcompute,networkandI/Oresources with multiple users and applications in order to drive higher utilisation rates, it replaces the traditional physical isolation boundaries with virtual ones. This fundamentalchangeinisolationboundariesintroduces new riskvectorsfordata leakage, cross-contamination as well as new requirements for the auditing and monitoring of such virtualised systems. In order to allow the deployment of e-Government, e-Health or other ap- plication services that use, store, and process highly sensitive data, there are a number of significant, common, complex issues which must be addressed by virtualisation technologies and solutions which have particular relevance: (cid:129) Compliance with legal frameworks for data protection and privacy (cid:129) Identity management between different governmentalservices (cid:129) Security and trust aspects of using virtualisation in a distributed environment (cid:129) Policy mapping (existing security and trust systems with virtualisation solutions) (cid:129) Management of risks and policy compliance verification. The First International Workshop on Security and Trust for Applications in Virtualised Environments (STAVE 2011) brought together industry executives, seasoned managers, agency representatives, expert researchers and senior sub- ject matter experts from a broad array of application and technical areas, as well as government officials who are concerned with security and trust in virtu- alised environments. It drew out common themes, problems and issues that are encountered,andthesolutionsthathavebeendevisedtodealwiththeproblems of securing virtualised environments and compliance with government regula- tions. It aimed to provide the basis for a common understanding and common approaches to security and trust that synthesises the insights and best of breed solutions being developed in the diverse areas in which these problems are en- countered.
