2009 ACM Workshop on Secure Web Services (SWS) http://sesar.dti.unimi.it/SWS09/ November 13, 2009 Hyatt Regency, Chicago, USA. Held in conjunction with the 16th ACM Conference on Computer and Communications Security (CCS 2009) Call for Papers Basic security protocols for Web Services, such as XML Security, the WS-* series of proposals, SAML, and XACML are the basic set of building blocks enabling Web Services and the nodes of GRID architectures to interoperate securely. While these building blocks are now firmly in place, a number of challenges are still to be met for Web services and GRID nodes to be fully secured and trusted, providing for secure communications between cross-platform and cross-language Web services. Also, the current trend toward representing Web services orchestration and choreography via advanced business process metadata is fostering a further evolution of current security models and languages, whose key issues include setting and managing security policies, inter-organizational (trusted partner) security issues and the implementation of high level business policies in a Web services environment. The SWS workshop explores these challenges, ranging from the advancement and best practices of building block technologies such as XML and Web services security protocols to higher level issues such as advanced metadata, general security policies, trust establishment, risk management, and service assurance. The workshop provides a forum for presenting research results, practical experiences, and innovative ideas in web services security. Topics of interest include, but are not limited to, the following: * Web services and GRID computing security * Authentication and authorization * Frameworks for managing, establishing and assessing inter-organizational trust relationships * Web services exploitation of Trusted Computing * Semantics-aware Web service security and Semantic Web Secure orchestration of Web services * Privacy and digital identities support Important Dates * Paper submissions due: June 12th, 2009. * Acceptance notifications: August 16th, 2009. * Camera-ready papers due: August 25th, 2009. Submitted papers must not substantially overlap papers that have been published or that are simultaneously submitted to a journal or a conference with proceedings. Submissions must be at most ten pages in double-column ACM format (note: pages must be numbered), excluding the bibliography and well-marked appendices and at most 12 pages overall. Committee members are not required to read appendices, so the paper should be intelligible without them. All submissions must be anonymized (an author's name should only occur in references to that author's related work, which should be referenced in the third person and not overtly distinguishable from the referenced work of others). Submissions should be made electronically in PDF or portable Postscript format using the SWS09 Submission System at https://www.easychair.org/login.cgi?conf=sws09 *CCS General Chair Ehab Al-Shaer, DePaul University, USA. *SWS Program co-Chairs Ernesto Damiani, Information Technology Department, Università degli Studi di Milano, Italy.
