The 16th ACM Symposium on Access Control Models and Technologies (SACMAT) June 15-17, 2011 Innsbruck, Austria Call for Papers, Panel Proposals and System Demonstrations Due dates for submissions: Abstract: Jan 7, 2011 Paper, panel proposal, demo proposal: Jan 14, 2011 ACM SACMAT is the premier forum for the presentation of research results and experience reports on leading edge issues of access control, including models, systems, applications, and theory. The aims of the symposium are to share novel access control solutions that fulfil the needs of heterogeneous applications and environments, and to identify new directions for future research and development. SACMAT provides researchers and practitioners with a unique opportunity to share their perspectives with others interested in the various aspects of access control. Papers offering novel research contributions in all aspects of access control are solicited. Accepted papers will be presented at the symposium and published by the ACM in the symposium proceedings. We solicit proposals for panels and systems demonstrations as well. Topics of Interest * Access control models and extensions * Access control requirements * Access control design methodology * Access control mechanisms, systems, and tools * Access control in distributed and mobile systems * Access control for innovative applications * Administration of access control policies * Delegation * Identity management * Policy/Role engineering * Safety analysis and enforcement * Standards for access control * Trust management * Trust and risk models in access control * Theoretical foundations for access control models * Usability in access control systems * Usage control Please visit http://sacmat.org/ for more information and instructions for submission.
