An Integrated Detection System Against False Data Injection Attacks in the Smart Grid

March 4, 2014
Author(s)
Wei Yu, David W. Griffith, Linqiang Ge, Sulabh Bhattarai, Nada T. Golmie
The smart grid is a new type of power grid that will use the advanced communication network technologies to support more efficient energy transmission and distribution. The grid infrastructure was designed for reliability; but security, especially against

Trust Issues with Opportunistic Encryption

February 28, 2014
Author(s)
Scott W. Rose
Recent revelations have shed light on the scale of eavesdropping on Internet traffic; violating the privacy of almost every Internet user. In response, protocol designers, engineers and service operators have begun deploying encryption (often opportunistic

A Spectral Analytic Method for Fingerprint Image Sample Rate Estimation

February 25, 2014
Author(s)
John M. Libert, Shahram Orandi, John D. Grantham, Michael D. Garris
This study examines the use of the NIST Spectral Image Validation and Verification (SIVV) metric for the application of detecting the sample rate of a given fingerprint digital image. SIVV operates by reducing an input image to a 1-dimensional power

Framework for Improving Critical Infrastructure Cybersecurity

February 19, 2014
Author(s)
Kevin M. Stine, Kim Quill, Gregory A. Witte
Recognizing that the national and economic security of the United States depends on the resilience of critical infrastructure, President Obama issued Executive Order (EO) 13636, Improving Critical Infrastructure Cybersecurity, in February 2013. It directed

Framework for Improving Critical Infrastructure Cybersecurity, Version 1.0

February 12, 2014
Author(s)
Adam Sedgewick
The national and economic security of the United States depends on the reliable functioning of critical infrastructure. Cybersecurity threats take advantage of the increased complexity and connectivity of critical infrastructure systems, placing the Nation

Estimation of uncertainty in application profiles

February 3, 2014
Author(s)
David W. Flater
Application profiling tools are the instruments used to measure software performance at the function and application levels. The most powerful measurement method available in application profiling tools today is sampling-based profiling, where a

IT Risks

February 3, 2014
Author(s)
Linda Wilbanks, D. Richard Kuhn, Wes Chou
Risk management is a common phrase when managing information, from the CISO to the programmer. We acknowledge that risk management is the identification, assessment and prioritization of risks and reflects how we manage uncertainty. These are some areas of

Dynamic Spectrum Access: Current State of the Art and Future Challenges

February 2, 2014
Author(s)
Anirudha Sahoo, Michael R. Souryal
Dynamic Spectrum Access (DSA) is emerging as a promising technology to mitigate the spectrum scarcity caused by static frequency allocations. Despite the clear need for more efficient allocation, however, DSA faces a number of challenges, chief among them

The neural representation of faces and bodies in motion and at rest

January 29, 2014
Author(s)
P J. Phillips, Alice O'Toole, Vaidehi Natu, Xiaobo An, Rice Allyson, James Ryland
The neural organization of person processing relies on brain regions functionally selective for faces or bodies, with a subset of these regions preferring moving stimuli. Although the response properties of the individual areas are well established, less

Optimal Spread in Network Consensus Models

January 27, 2014
Author(s)
Fern Y. Hunt
Suppose we seek a set of nodes in a network that will enable the fastest spread of information in a decentralized communication environment. If communication resources are limited there are constraints on the number of nodes that can be selected. In this
