Workshop on Security in Communications Networks Held in Conjunction with IEEE LCN 2012 Clearwater, FL October 22-25, 2012 Secure Group Communications Recent years have seen growth in the number of services and applications that enable groups of people and/or devices to communicate and collaborate in real-time. Oftentimes, these groups are spontaneously formed based on a common interest or objective, have a limited life span and use one or more network technologies to connect group members with available resources and each other. Examples range from multi-player online games and video conferencing to the coordination of first responders at a crime scene or troops in a battlefield. Secure group communication is a difficult problem that needs to be addressed to guarantee the confidentiality, integrity, and availability of these applications. Challenges include user mobility, device heterogeneity, lack of infrastructure, cross domain interactions, as well as dynamic memberships without pre-configuration. The main purpose of this workshop is to promote further research interests and activities on Secure Group Communication. This workshop aims to increase the synergy between academic and industrial researchers working in this area. We are interested in experimental, systems-related, and work-in-progress papers in all aspects of Secure Group Communications. The topics of interest include (but are not limited to): * Novel and emerging secure architectures * Study of attack strategies, attack modeling * Case studies and analysis of actual attacks * Group key management (incl. dynamic key generation, distribution, update and revocation) * Context/capability/situational-aware group memberships * Identity management * Protection of video and multimedia content * Secure multicast * Secure collaborative services * Secure data accumulation, storage and access control * Tradeoffs between security vs. performance vs. usability * Secure group communications in mobile ad hoc, mesh, vehicular and incident area networks, etc. Dates: Submission: May 12, 2012 Notification: June 30, 2012 Camera Ready: July 28, 2012 Workshop: October 22-25, 2012 http://www.sick-workshop.org/
