INTRICATE-SEC 2016: http://infosec.cs.uct.ac.za/INTRICATE-SEC/ Fourth International Workshop on Security Intricacies in Cyber-Physical Systems and Services(INTRICATE-SEC 2016) held in conjunction with the 30th International Conference on Advanced Information Networking and Applications (AINA-2016) Crans-Montana, Switzerland, March 23-25, 2016. For INTRICATE-SEC 2016 we are expanding our scope from a focus on security intricacies in designing/modelling service oriented architectures to the broader field of secure cyber physical systems (CPS) and services. Of particular interest are ideas and solutions on provisioning secure CPS and services over resource constrained and low power lossy networks. In addition to invited talks, we welcome papers with novel theoretical and application-centered contributions focused on (but not restricted to) the following topics: - Security and Privacy for CPS - Anonymity and Pseudonymity - Authentication and Authorization - Trust & Identity Management - Privacy - Malware - Secure Service Platforms for CPS - Smart Grids - Demand Management - Scheduling - Energy Management Models - Mobile Web Services and Middleware - Secure Architectures for CPS - Data Modeling - Home Energy Management - Scalability, Reliability, and Safety - Resource Constrained and Low Power Lossy Networks - Unconventional/Biologically Inspired Models Submission Deadline: Oct. 3, 2015 Author Notification: Dec. 20, 2015 Final Manuscript: Jan. 20, 2016 Author Registration: Jan. 20, 2016 For more information, please see http://infosec.cs.uct.ac.za/INTRICATE-SEC/
