Joint Cyber and Physical Attacks on Power Grids: Graph Theoretical Approaches for Information Recovery
"... Recent events demonstrated the vulnerability of power grids to cyber attacks and to physical attacks. Therefore, we focus on joint cyber and physical attacks and develop methods to retrieve the grid state information following such an attack. We consider a model in which an adversary attacks a zone ..."

Seminar in Identity, Privacy and Security: Cyber-Physical Security of the Smart Grid
"... Information technology facilitates greater efficiency, cost effectiveness and timeliness of data thus driving cyber-enabled innovation. The higher granularity and accessibility to personal and sensitive data in our information-driven world, however, brings forth natural challenges in addressing iden ..."

and complexity of the smart grid provides a natural framework to discuss diverse threats and attacks, and multidisciplinary mitigation approaches. Moreover, the smart grid also represents a prototypical cyber-physical system requiring a recasting of the classical definitions for security to include a cyber-physical
On the Use of Cyber-Physical Hierarchy for Smart Grid Security and Efficient Control
- in IEEE Canadian Conference on Electrical and Computer Engineering (CCECE
, 2012
"... We study the application of cyber-physical hierarchy on a class of smart grid systems to improve scalability. Our framework employs a multi-agent flocking-based approach to study the transient stability problem in emerging power systems. An agent in this context em-bodies a coherent group of system ..."

improves communications and energy overhead by introducing cyber couplings only within components of the smart grid where physical relationships are insufficient for transient stability in the face of a incidental fault or intentional at-tack. We demonstrate the performance of our approach on the 9-bus
Detection of Faults and Attacks Including False Data Injection Attack in Smart Grid Using Kalman Filter
"... Abstract—By exploiting the communication infrastructure among the sensors, actuators, and control systems, attackers may compromise the security of smart-grid systems, with tech-niques such as denial-of-service (DoS) attack, random attack, and data-injection attack. In this paper, we present a mathe ..."

Modeling and Recognition of Smart Grid Faults by a Combined Approach of Dissimilarity Measures and One-Class Classification
, 2014
"... Detecting faults in electrical power grids is of paramount importance, either from the electricity operator and consumer viewpoints. Modern electric power grids (smart grids) are equipped with smart sensors that allow to gather real-time information regarding the physical condition of the elements f ..."

Cyber Security for Power Grids
, 2009
"... Power grids worldwide are undergoing a revolutionary transition as so-called “smart grids” that exploit renewable energy sources are emerging. As such distributed power generation requires networked control, future power systems will become more exposed to cyber attacks. This paper discusses cyber s ..."

A Flocking-Based Paradigm for Hierarchical Cyber-Physical Smart Grid Modeling and Control
"... Abstract—It is well known that information will play an impor-tant role in enhancing emerging smart grid system operation. Therefore, questions naturally arise as to when the increased data-dependence may be considered excessive. Two practical considerations emerge: 1) communications and computation ..."

A Smart Grid Vulnerability Analysis Framework for Coordinated Variable Structure Switching Attacks
"... Abstract—In this paper we have proposed an approach for vulnerability analysis of a class of cyber-physical reconfiguration attacks called coordinated variable structure switching. In such an attack, an opponent who gains control over a target circuit breaker, relay or switch can apply a given switc ..."
