There has recently been a major shift in news related media consumption trends and readers are increasingly relying on just-in-time news feeds versus the traditional newspaper print medium. Cloud-networked infrastructures are being setup by the media companies to aggregate news feeds from affiliates, and to meet the elastic demands of Internet-scale users accessing news feeds. However, cyber attacks...
Information flow typically refers to the explicit as well as implicit information resulting from the interaction of cyber processes constituting a system. Information flow also occurs in cyber-physical systems (CPSs). Information flow is difficult to detect in CPSs, due to their physical nature and complex interactions among various computational and physical components. In this work, formal methods...
Information flow is a fundamental concept underlying the security of a system. Confidentiality of information in a system can be breached through unrestricted information flow. Physical components added to a cyber system considerably increase the difficulty of determining information flow and the difficulty of mitigating the corresponding confidentiality problem. Fundamentally, physical actions inherently...
The FREEDM microgrid is a test bed for a smart grid integrated with Distributed Grid Intelligence (DGI) to efficiently manage the distribution and storage of renewable energy. Within the FREEDM system, DGI applies distributed algorithms in a unique way to achieve economically feasible utilization and storage of alternative energy sources in a distributed fashion. The FREEDM microgrid consists of residential...
The FREEDM microgrid is a smart grid solution with Distributed Grid Intelligence (DGI) to efficiently manage the power distribution and storage of renewable energy. Within the FREEDM system, DGI applies distributed control method in a unique way to achieve feasible load balancing in microgrid by migrating power between renewable energy generation and storage at each node. This paper presents the key...
