The Smart Energy Grid Security (SEGS) Workshop aims to foster innovative research and discussion about smart energy grid security and privacy challenges, issues, approaches, and solutions. SEGS’13 takes places on November 8, 2013 in Berlin, Germany in conjunction with ACM CCS 2013. SEGS seeks paper submissions from academia, industry, and government institutions presenting novel research on all theoretical and practical aspects of smart grid security and privacy, including design, analysis, experimentation, and fielded systems. We encourage submissions from other communities, such as law, economics, and HCI, that present these communities’ perspectives on technological issues. The scope of the workshop encompasses all aspects of the smart grid, including distribution, transmission, generation, metering, e-mobility, and integration of distributed energy resources.
