This document is the action plan to improve the suitability of ASTM Continuity of Care Record (CCR) to support the Department of Health and Human Services’ Stage 1 Meaningful Use. Lantana Consulting Group prepared this report for the National Institute of

An IEEE 1588 Performance Testing Dashboard for Power Industry Requirements

September 12, 2011
Author(s)
Julien M. Amelot, Ya-Shian Li-Baboud, Clement Vasseur, Jeffrey Fletcher, Dhananjay Anand, James Moyne
The numerous time synchronization performance requirements in the Smart Grid entails the need for a set of common metrics and test methods to verify the ability of the network system and its components to meet the power industry's accuracy, reliability and

Interference Mitigation for Body Area Networks

September 12, 2011
Author(s)
Wen-Bin Yang, Kamran Sayrafian
Due to ultra-low power communication, BAN is most likely a victim system. Interference from other BANs or other coexisting wireless communication systems may be significant. Power control is usually inefficient and may even cause more interference in an

Defining AFIS Latent Print "Lights-Out"

September 8, 2011
Author(s)
Stephen Meagher, Vladimir N. Dvornychenko
The term "lights-out" for AFIS ten-print fingerprint operations has been around for many years and is generally understood to mean "no human intervention is involved." But is this term appropriate for AFIS latent print operations? This IR examines seven

NIST Cloud Computing Reference Architecture

September 8, 2011
Author(s)
Fang Liu, Jin Tong, Jian Mao, Robert B. Bohn, John V. Messina, Mark L. Badger, Dawn M. Leaf
The adoption of cloud computing into the Federal Government and its implementation depend upon a variety of technical and non-technical factors. A fundamental reference point, based on the NIST definition of Cloud Computing, is needed to describe an

Cost-Efficient Routing with Controlled Node Mobility in Sensor Networks

September 1, 2011
Author(s)
Kamran Sayrafian
In this paper, an energy-efficient strategy is proposed for tracking a moving target in a mobile sensor network. The energy expenditure of the sensors in the network is assumed to be due to communication, sensing and movement. First, the target area is

NIST NCPDP Analysis - Suitability Assessment

August 31, 2011
Author(s)
Frank McKinney
This document completes the review of the NCPDP SCRIPT standard by reporting on several aspects related to its suitability as a standard to support Meaningful Use, including: completeness, correctness and internal consistency of the standard, ease of

Testability Report for SCRIPT

August 31, 2011
Author(s)
Ioana Singureanu
This document summarizes the major testability issues raised by the NCPDP SCRIPT Implementation Guide Version 10.6. The ELR Implementation Guide is intended as a means of testing and certifying Electronic Health System (EHRS) for Meaningful Use.

An Empirical Study of a Vulnerability Metric Aggregation Method

August 18, 2011
Author(s)
Su Zhang, Xinming Ou, Anoop Singhal, John Homer
Quantifying security risk is an important and yet difficult task in enterprise network risk management, critical for proactive mission assurance. Even though metrics exist for individual vulnerabilities, there is currently no standard way of aggregating

NIST-SP 500-291, NIST Cloud Computing Standards Roadmap

August 10, 2011
Author(s)
Michael D. Hogan, Fang Liu, Annie W. Sokol, Tong Jin
The NIST Cloud Computing Standards Roadmap Working Group has surveyed the existing standards landscape for security, portability, and interoperability standards/models/studies/use cases, etc., relevant to cloud computing. Using this available information

Smart Clocks Have a Hand in the Smart Grid

July 29, 2011
Author(s)
Jeffrey Fletcher, Dhananjay Anand, Maruthi Chaluvadi, Julien M. Amelot, Ya-Shian Li-Baboud, James Moyne
Clock synchronization is becoming an increasingly important characteristic of modern wide area monitoring and control systems such as the power grid. It provides an opportunity to coordinate control actions and measurement instants across hundreds of miles

A public randomness service

July 21, 2011
Author(s)
Michael J. Fischer, Michaela Iorga, Rene Peralta
We argue for the deployment of sources of randomness on the Internet for promoting and enhancing electronic commerce. We describe, in rough detail, our planned implementation of such a source.

Predicting Failure in Complex Systems by Perturbing Markov Chain Models

July 21, 2011
Author(s)
Christopher E. Dabrowski, Fern Y. Hunt
In recent years, substantial research has been devoted to monitoring and predicting performance degradations in real-world complex systems within large entities such as nuclear power plants, electrical grids, and distributed computing systems. Special

Predicting Macroscopic Dynamics in Large Distributed Systems

July 18, 2011
Author(s)
Kevin L. Mills, James J. Filliben
In this paper, we outline an approach that can be used to predict macroscopic dynamics when new components are deployed in a large distributed system. Our approach combines two main methods: scale reduction and multidimensional data analysis techniques

On the Security of Hash Functions Employing Blockcipher Postprocessing

July 14, 2011
Author(s)
Dong H. Chang, Mridul Nandi, Moti Yung
Analyzing desired generic properties of hash functions is an important current area in cryptography. For example, in Eurocrypt 2009, Dodis, Ristenpart and Shrimpton introduced the elegant notion of "Preimage Awareness" (PrA) of a hash function H^P , and

USABILITY STANDARDS ACROSS THE DEVELOPMENT LIFECYCLE
