============================================================

The organizing committee of the 25th ACM Symposium on Access Control Models and Technologies (SACMAT 2020) invites contributions on all aspects of access control. The symposium will provide participants the opportunity to present work at different levels of development, from early work on promising ideas to fully developed technical results as well as system demonstrations. The symposium will feature a Best Paper Award. The program will include keynote talks, research paper presentations, demos, a panel, and a poster session.

CALL FOR RESEARCH PAPERS
========================

Papers offering novel research contributions are solicited for submission. Accepted papers will be presented at the symposium and published by the ACM in the symposium proceedings. In addition to the regular research track, this year SACMAT will again host a special track: Blue Sky/Vision Track. Researchers are invited to submit papers describing promising new ideas and challenges of interest to the community as well as access control needs emerging from other fields. We are particularly looking for potentially disruptive and new ideas which can shape the research agenda for the next 10 years. We encourage submissions that present ideas that may have not been completely developed and experimentally evaluated. Submissions to the regular track covering any relevant area of access control are welcomed. Areas include, but are not limited to, the following:

- Applications
- Authentication
- Big data
- Biometrics
- Blockchain
- Cloud computing and edge computing
- Cryptographic approaches
- Cyber-physical systems and Internet of Things (IoT)
- Databases and data management
- Data leakage prevention
- Data protection on untrusted infrastructure
- Distributed and mobile systems
- Economic models and game theory
- Enforcement
- Hardware enhanced security, trusted execution environments
- Identity management
- Machine learning
- Mechanisms, systems, and tools
- Models and extensions
- Multimedia
- Network access control
- Obligations
- Privacy
- Policy engineering and policy mining
- Policy analysis and policy verification
- Requirements
- Risk and uncertainty
- Theoretical foundations
- Trust management
- Usability

REGULAR TRACK PAPER SUBMISSION AND FORMAT
=========================================

Papers must be written in English. Authors are required to use the ACM format for papers, using the two-column SIG Proceedings Template (the sigconf template for LaTex) in the following link:
https://www.acm.org/publications/authors/submissions
The length of the paper in the proceedings format must not exceed twelve US letter pages formatted for 8.5" x 11" paper. The file should be in PDF format and 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. 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. Submissions should be made to the EasyChair conference management system by the paper submission deadline of February 10, 2020, at this URL:
https://easychair.org/conferences/?conf=sacmat20

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. Wherever appropriate, relevant related work, including that of the authors, must be cited. Submissions that are not accepted as full papers may be invited to appear as short papers. At least one author of each accepted paper much register for the conference prior to the camera-ready deadline.

BLUE SKY/VISION TRACK PAPER SUBMISSION AND FORMAT
=================================================

All submissions to this track should be in the same format as for the regular track, but the length must not exceed ten US letter pages, and the submission should not be anonymized. Submissions to this track should be submitted to the EasyChair conference management system by the same deadline as for the regular track.

CALL FOR POSTERS
================

SACMAT 2020 will include a poster session to promote discussion of ongoing projects among researchers in the access control field. Posters can cover preliminary or exploratory work with interesting ideas, or research projects in early stages with promising results in all aspects of access control. Authors interested in displaying a poster must submit a poster abstract in the same format as for the regular track, but the length must not exceed three US letter pages, and the submission should not be anonymized. The title should start with "Poster:". Accepted poster abstracts will be included in the conference proceedings. Submissions should be emailed to the poster chair, Edelmira Pasarella (edelmira@cs.upc.edu), by Apr 1, 2020, 5PM PDT. The subject line should include "SACMAT 2020 Poster:" and the poster title.

CALL FOR DEMOS
==============

A demonstration proposal should clearly describe (1) the overall architecture of the system or technology to be 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.

Demonstration proposals should be in the same format as for the regular track, but the length must not exceed four US letter pages, and the submission should not be anonymized. A two-page description of the demonstration will be included in the conference proceedings. Submissions should be emailed to the Demonstrations Chair, Edelmira Pasarella (edelmira@cs.upc.edu), by Apr 1, 2020, 5pm PDT. The subject line should include "SACMAT 2020 Demo:" and the demo title.
