Call for Papers Papers offering novel research contributions in all aspects of access control are solicited for submission to the 19th ACM Symposium on Access Control Models and Technologies (SACMAT 2014, http://www.sacmat.org). Accepted papers will be presented at the symposium and published by the ACM in the symposium proceedings. June 25-27, 2014 London, Ontario, Canada *New for 2014* We have expanded the scope to include several new topics that have relevance to access control. These include cyber-physical systems, applications, systems, hardware, cloud computing, and usability. The Program Committee for this year reflects this expanded scope. Important DatesPaper, Demonstration and Panel proposal submissions due: February 13, 2014 (23:59 Pacific Time) (no extensions) Notification to authors: April 7, 2014 Camera-ready submission due: May 4, 2014 Conference: June 25-27, 2014 Topics of Interest related to Access Control Administration Applications Attribute-based systems Authentication Biometrics Cryptographic approaches Cyber-physical systems Design methodology Distributed, cloud, and mobile systems Economic models and game theory Enforcement Hardware enhanced Identity management Mechanisms, systems, and tools Models and extensions Obligations Policy engineering and analysis Requirements Risk Safety analysis Standards Theoretical foundations Trust management Usability Paper Submission and FormatPapers are to be submitted electronically using the EasyChair conference management system (https://www.easychair.org/conferences/?conf=acmsacmat14). Papers must be submitted as a single PDF file, formatted for 8.5" X 11" paper, and be no more than 5MB in size. It is the responsibility of the authors to ensure that their submission will print easily on simple default configurations. Papers must be written in English. Authors are required to use the ACM format for papers, using one of the ACM SIG Proceedings Templates (http://www.acm.org/sigs/pubs/proceed/template.html). The length of the paper (in the proceedings format) must not exceed ten US letter pages, excluding well-marked appendices, and no more than twelve pages in total. Committee members are not required to read the appendices, so papers must be intelligible without them. The submission must be anonymous, so information that might identify the authors - including author names, affiliations, acknowledgements, or obvious self-citations - must be excluded. It is the authors' responsibility to ensure that their anonymity is preserved when citing their own work. All submissions must contain a significant original contribution. That is, submitted papers must not substantially overlap papers that have been published or that are simultaneously submitted to a journal, conference or workshop. In particular, simultaneous submission of the same work is not allowed. Where appropriate, relevant related work, including that of the authors, must be cited. Panel Proposal Submission Panel proposals should be no longer than two pages, and should identify potential panelists, indicating those who have confirmed their willingness to participate. We especially solicit panels with participants from industry and/or government. Proposals can be e-mailed to the Panels Chairs, Florian Kerschbaum (florian.kerschbaum@sap.com) and Lujo Bauer (lbauer@cmu.edu). System Demonstration Submission Since 2011, SACMAT has included system demonstration sessions during the symposium. To be considered for presentation, authors should submit a *four-page* demonstration proposal prepared according to the formatting guidelines described above for regular papers. However, demonstration proposals are *not* subject to double-blind review, hence author name(s) and affiliation(s) should be included in the submission. Demonstration proposals will be included in the final proceedings. Demonstration proposals should clearly describe (1) the overall architecture of the system or technology demonstrated, and (2) one or more demonstration scenarios that describe how the audience, interacting with the demonstration system or the demonstrator, will gain an understanding of the underlying technology. Submissions will be evaluated based on the motivation of the work behind the use of the system or technology to be demonstrated and its novelty. Authors can submit their four-page proposals via EasyChair (https://www.easychair.org/conferences/?conf=acmsacmat14). Questions about the system demonstration session or demonstration proposals can be emailed to the demonstrations chair, Adam J. Lee (adamlee@cs.pitt.edu).
