Visible to the public CPS: Synergy: High-Fidelity, Scalable, Open-Access Cyber Security Testbed for Accelerating Smart Grid Innovations & Deployments

Submitted by Mani Govin on Mon, 02/01/2016 - 1:26pm. Contributors:

Cybersecurity and resiliency of the power grid is of paramount importance to national security and economic well-being. CPS security testbeds are enabling technologies that provide realistic experimental platforms for the evaluation and validation of security technologies within controlled environments. In this regard, the following are the key objectives of the project:

Visible to the public CPS: Breakthrough: Distributed Computing under Uncertainty: A New Paradigm for Cooperative Cyber-Physical Systems

Submitted by Nicola Elia on Mon, 02/01/2016 - 5:36am. Contributor:

Abstract:

This project is to develop dynamical models of distributed computation systems that are resilient to noise, unreliable communication and other source uncertainty. The key idea is centered on the development of optimization systems. These are dynamical systems that (solve) stabilize around the optimal solution of a (static) convex optimization problem. If the optimization problem is separable, then the designed dynamic system decomposes into a set of locally interacting dynamic systems.

Visible to the public A Unified System Theoretic Framework for Cyber Attack-Resilient Power Grid

Submitted by Umesh Vaidya on Mon, 02/01/2016 - 5:36am. Contributors:

Abstract:

We developed a systematic analytical and computational framework for the vulnerability analysis and mitigation of data integrity attacks on Phasor Measurement Units (PMUs) employed for wide area monitoring and control of power system. The analytical framework is based on the stability theory of stochastic dynamical system and it allows one to systematically determine the PMUs most critical to power network security.

Visible to the public A Knowledge Representation and Information Fusion Framework for Decision Making in Complex Cyber-Physical Systems

Submitted by Soumik Sarkar on Mon, 02/01/2016 - 5:36am. Contributor:

Abstract:

Modern distributed cyber-physical systems (CPSs) encounter a large variety of physical faults and cyber anomalies and in many cases, they are vulnerable to catastrophic fault propagation scenarios due to strong connectivity among the sub-systems.

Visible to the public Detecting and Recovering from Faults in Programmed Molecular Systems

Submitted by Robyn.Lutz on Wed, 12/23/2015 - 4:12pm. Contributors:

Abstract:

For reliable operation of programmed molecular systems, the capability to detect faults when they occur and to initiate recovery is essential. Since a faulty system cannot be depended upon to report its own failure, a monitoring device is needed. The work presented here describes the design of one such fault protection device, called a molecular watchdog timer.
